EXTRA FEATURE - REPORT ON SEVERE SOUTH AMERICAN EXTRATROPICAL CYCLONES
----------------------------------------------------------------------
The following report is based on information sent to the author by
Alexandre Aguiar and Eugenio Hackbart of the Metsul Climatologia Urbana
Weather Center in Porto Alegre, Brazil. A special thanks to these
fellows for sending the information (as well as damage photos, which
unfortunately can't be included here in a strictly text file) on these
unusually intense extratropical cyclones which affected their corner of
the world during August and early September.
A. Storm #1
-----------
On August 9 an extratropical cyclone affected Florianopolis, the
capital of the state of Santa Catarina in Brazil. One weather station
in the Arvoredo Island, right off the coast, registered gusts of 140 kph
(76 kts). In the Florianopolis Hercilio Luz Airport the wind gusted to
90 kph (49 kts) and was strong enough to move airplanes. Large areas of
the city remained without power for up to two days and many trees were
blown down.
B. Storm #2
-----------
The most astonishing event took place on the night of August 23rd in
Uruguay. The national capital, Montevideo, was hit by winds of almost
200 km/h (109 kts) due to another extratropical cyclone. It was the
worst storm to affect Brazil's neighboring country since 1966. Following
is a wire from the Associated Press:
"In Uruguay, a powerful storm system on the 23rd-24th produced
strong winds in excess of 160 km/hr (87 kts) in the departments
of Canelones, Montevideo, San Jose, Colonia and Maldonado, where
nearly 70 percent of the country's population live. Thousands of
homes were damaged and around 20,000 people lost electricity and
telephone service. Montevideo's international airport was
temporarily shut down late on the 23rd due to the high winds and
heavy rainfall. There were seven people killed and dozens injured
(Associated Press/OCHA)."
A station located on the Harbor of Montevideo registered a gust of
187 kph (102 kts). Very similar wind gusts were also observed at
Montevideo's Carrasco International Airport with one gust reaching
173 kph (94 kts). Montevideo was affected by tropical storm-force
winds for over 12 hours and by hurricane-force winds for nearly
four hours.
Local officials and private weather services were plunged into
a crisis after the storm because just three hours before the high
winds a storm advisory pointed to winds of a maximum of 60 kph. We
here in Brazil had issued an warning of 100+ kph winds for southern
Uruguay, but the warning never arrived to our Uruguayan pals as it
was published in Portuguese in a private weather institution in
another country. Days after the storm we decided to contact local
weather services in Uruguay and initiate permanent cooperation for
the weather systems that affect Rio Grande do Sul, the southernmost
state in Brazil, since they normally pass first through Uruguay. In
those contacts, Uruguayan meteorologists made dramatic descriptions of
the storm.
More than three thousand trees fell in the city of 1.5 million
people and 10 people died. Two died when a 100-meter FM radio station
tower collapsed onto houses and buildings. Downtown high-rise buildings
were shaking during the storm and some news stands rolled over four
blocks. In ANTEL's Tower, the building that hosts the national phone
company, a car was thrown by the winds into the front entrance.
The low pressure system migrated from northern Argentina, crossed
through southwest Rio Grande do Sul (Brazil) and literally exploded
in intensity over the waters of Rio de la Plata. The lowest reported
pressure was 991.7 hPa. (Note: Extratropical cyclones in this part of
the globe are common during fall, winter and spring months. The winds
usually peak to 80-110 kph (43-60 kts), but winds of 187 kph are very
unusual.)

C. Storm #3
-----------
On September 2nd another extratropical cyclone affected South
America's South Cone. This time our city and state were punished by
the winds. In the metropolitan area of Porto Alegre power outages
left many thousands of people without power. Windows were blown in,
and roughly 300 trees fell down. In the coastal areas many homes were
de-roofed and some injuries were reported. The highest wind gust was
observed in the weather station located in the harbor of Rio Grande, in
the southern coast of the state: 111 kph (60 kts). Near downtown Porto
Alegre winds peaked at 100 kph (54 kts).

Sources of Information
----------------------
Most of the information presented below is based upon tropical
cyclone warnings and significant tropical weather outlooks issued
by the Joint Typhoon Warning Center of the U. S. Air Force and
Navy (JTWC), located at Pearl Harbor, Hawaii. In the companion
tropical cyclone tracks file, I normally annotate track coordinates
from some of the various Asian warning centers when their center
positions differ from JTWC's by usually 40-50 nm or more. All
references to sustained winds imply a 1-minute averaging period
unless otherwise noted.
Michael V. Padua of Naga City in the Philippines, owner of the
Typhoon 2000 website, normally sends me cyclone tracks based upon
warnings issued by the Japanese Meteorological Agency (JMA) and the
Philippine Atmospheric, Geophysical & Astronomical Services
Administration (PAGASA). Also, Huang Chunliang of Fuzhou City, China,
sends data taken from synoptic observations around the Northwest
Pacific basin. A very special thanks to Michael and Chunliang for
the assistance they so reliably provide.
In the title line for each storm I have referenced all the cyclone
names/numbers I have available: JTWC's depression number, the
JMA-assigned name (if any), JMA's tropical storm numeric designator,
and PAGASA's name for systems forming in or passing through their
area of warning responsibility.
Northwest Pacific Tropical Activity for August
----------------------------------------------
The Northwest Pacific basin was very active during the month of
August. Six tropical cyclones became named tropical storms with five
reaching typhoon intensity, and of these, two were declared super
typhoons per JTWC's analysis. In addition to the six named storms,
three systems were treated as tropical depressions by JMA and some of
the other Asian TCWCs, but not by JTWC. Of these three tropical
depressions, the first was a weak system mentioned only by JMA in their
High Seas Bulletins, and only on 3 August. On that day the depression
was located well in the subtropics, near 30N/151E, and appeared to be
quasi-stationary. No winds were given, and likely the MSW did not
exceed 20 or 25 kts. This depression was not referenced at all in the
STWOs issued by JTWC, and given the latitude, was likely hybrid in
nature. The other two non-developing tropical depressions were both
spawned in the South China Sea, and while following different tracks,
both ultimately entered the Gulf of Tonkin and made landfall in Vietnam.
Short reports sent by Huang Chunliang containing rainfall observations
for these systems follow.
Except for Tropical Storm Guchol, which recurved well south and east
of Japan, all the remaining named cyclones made landfall in various
Western Pacific rim nations, some with disastrous results. Japan was
struck by Typhoons Mawar and Nabi, the latter also passing through the
Mariana Islands at typhoon strength. Typhoons Matsa, Sanvu and Talim all
ultimately made landfall on the Chinese mainland with Sanvu and Talim
also striking Luzon and Taiwan, respectively. Reports on all the named
tropical cyclones follow, authored by Kevin Boyle with additional data
sent by Huang Chunliang.
NOTE: I have not yet received Huang Chunliang's reports of meteorological
observations and storm effects in China from Tropical Storm Sanvu and
Typhoon Talim. When these become available I will include them as
addenda to a future summary.

TYPHOON MATSA
(TC-09W / TY 0509 / GORIO)
30 July - 8 August
----------------------------------------------
Matsa: contributed by Laos, means 'lady fish'
A. Storm Origins
----------------
On 30 July an area of convection developed approximately 100 nm east
of Yap. It was included in JTWC's STWO at 0300 UTC 30 July when
animated multi-spectral satellite imagery revealed consolidating deep
convection over a weak LLCC. An upper-level analysis indicated that
the disturbance was embedded in a moderate wind shear environment with
favourable diffluence aloft. Based on improved organization, JTWC
issued a TCFA at 30/1430 UTC followed by the first warning at 31/0000
UTC. TD-09W was quickly upgraded to a 35-kt tropical storm by JTWC at
31/0600 UTC, and named Matsa after JMA raised their 10-min avg MSW to
35 kts at 31/1200 UTC. Also, at 31/1200 UTC PAGASA assigned the name
Gorio after the system had drifted into their AOR.
B. Track and Intensity History
------------------------------
Initially moving west to west-northwestward, Tropical Storm Matsa
changed onto a northwesterly heading on 31 July under the steering
influence of a mid-level ridge to the east. Continuing northwestwards,
Matsa slowly strengthened and reached typhoon intensity at 0000 UTC on
2 August when it was located approximately 565 nm south of Okinawa.
Intensification continued to be rather slow on 2 August and satellite
imagery depictions were of limited deep convection in the northern
semicircle and inhibited poleward outflow. There was little change on
3 August and the MSW hovered at 75 kts for the majority of the day.
However, on 4 August, things improved and Typhoon Matsa became
better organized, reaching its peak intensity of 90 kts and 950 hPa at
04/1200 UTC when it was passing approximately 200 nm west-southwest of
Okinawa, Japan. On 5 August Typhoon Matsa began to weaken as it headed
northwestwards, lashing northern parts of Taiwan with torrential rains
and gale-force winds as the storm passed by to the north. Continuing
northwestward, Matsa made landfall near Wenling, China, as a minimal
typhoon around 05/1800 UTC, the second tropical cyclone to affect the
Chinese mainland in nearly two weeks. Once inland, Matsa was
downgraded to a tropical storm at 06/0000 UTC, and JTWC issued the
final warning at this time. JMA kept Matsa at tropical storm intensity
as the cyclone turned northward over eastern China until 07/1200 UTC,
when that agency released the last statement on this system.
NMCC estimated a peak intensity of 90-kts while all other Asian
agencies estimated peak MSW of 80 kts.

WEST/2005_09W_MATSA.gif>
C. Damage and Casualties
------------------------
Ten deaths were reported by the Chinese media. More than 1.24 million
people were evacuated ahead of the storm. Matsa caused extensive damage
to property and agriculture in mainland China with monetary figures
estimated at 14.5 million yuan (1.7 billion US dollars). Matsa also
affected Taiwan. Rainfall totals of nearly 50 inches (1270 mm) fell in
30 hours over the northern part of the island, causing landslides and
widespread flooding. Damages to agriculture were estimated at
T$47 million (1.5 million US dollars). No deaths were reported in
Taiwan.

D. Huang Chunliang Report from China
------------------------------------
{Part I} Landfalls
==================
According to the NMCC warnings, Typhoon 0509 (MATSA) made its first
landfall near Ganjiang Town, Yuhuan County, Taizhou City, Zhejiang
Province, around 05/1940 UTC (August) with a MSW of 45 m/s (90 kts) and
a CP of 950 hPa. Crossing the Gulf of Yueqing, the typhoon made a second
landfall near Qingjiang Town, Yueqing City (a sub-city of Wenzhou City),
Zhejiang Province, around 05/2020 UTC with the MSW and CP unchanged. The
weakening tropical cyclone then passed through Zhejiang, Anhui, Jiangsu
and Shandong Provinces successively before the center of Tropical Storm
Matsa entered the waters of the Bohai Sea from Shandong Peninsula around
08/0600 UTC. After fading into a tropical depression, Matsa made its
final landfall near Longwangtang Town (38.8 N, 121.4 E), Lvshunkou
District, Dalian City, Liaoning Province, around 08/2310 UTC with a MSW
of 12 m/s (25 kts) and a CP of 995 hPa. Eventually, NMCC declared Matsa
extratropical shortly after the final landfall.

TYPHOON SANVU
(TC-10W / TY 0510 / HUANING)
9 - 14 August
------------------------------------------------
Sanvu: contributed by Macao, is the Macanese word for coral, a hard
substance often used for making jewelry, formed by the skeletons
of tiny sea animals, massed together in great numbers. Many
Macao souvenirs are made of it.
A. Storm Origins
----------------
At 1430 UTC 8 August, an area of convection, located approximately
365 nm northwest of Palau, was first mentioned as a suspect area in a
STWO issued by JTWC. A 08/0904 UTC QuikScat pass indicated an elongated
LLCC while animated enhanced infrared imagery depicted cycling
convection on the periphery of this circulation. An upper-level analysis
revealed a moderate vertical wind shear environment, weak divergence, and
increasing 850-mb vorticity. The system gradually consolidated and a
TCFA was issued at 10/0000 UTC. The first warning on Tropical
Depression 10W was released at 10/1200 UTC, the centre being located
approximately 500 nm east of Manila, Philippines. At this time TD-10W
was well within PAGASA's AOR, that agency having already assigned the
name Huaning from their internal naming list. Moving west-northwestward
along the southern periphery of the subtropical ridge, TD-10W was
upgraded to a tropical storm at 11/0000 UTC. Following JMA's upgrade to
tropical storm intensity at 11/1200 UTC, the tropical cyclone was named
Sanvu.
B. Track and Intensity History
------------------------------
With the subtropical ridge firmly in place across the northwest
Pacific into eastern China, Tropical Storm Sanvu was foreordained to
track on a predominantly west-northwesterly track. Sanvu/Huaning
remained a weak tropical storm through 11 August while clipping the
northeastern corner of Luzon, Philippines. Satellite images showed
that the poleward outflow was being restricted due to subsidence
associated with the ridging to the north. However, on 12 August Sanvu
began to intensify and was upgraded to a 65-kt typhoon--its peak
intensity--at 0000 UTC 13 August while located approximately 165 nm
east of Hong Kong, China. By the time Sanvu made landfall near
Shantou, China, at around 13/0600 UTC, it had weakened to a 55-kt
tropical storm. As it was dissipating as a significant tropical
cyclone over land, the final warning was issued by JTWC. JMA
maintained Sanvu as a tropical storm until 14/0000 UTC when that agency
also released the final statement.
A peak intensity of 60 kts was estimated by both NMCC and HKO while
JMA and the Meteorological Department of Thailand estimated a MSW of 55
kts. The minimum CP estimated by JMA was 985 mb. The peak intensity
estimated by the CWB of Taiwan was 50 kts, which was also the highest
MSW per PAGASA's warnings while the storm was moving through their AOR.

WEST/2005_10W_SANVU.gif>
C. Damage and Casualties
------------------------
Typhoon Sanvu brought strong winds and torrential rains to southern
China. The winds brought down trees and sent billboards and telephone
boxes flying while torrential rains brought tremendous flooding. The
floodwaters destroyed more than 2,500 houses, many bridges, and damaged
60,000 hectares (148,000 acres) of crops. Two people were killed when
a two-metre wall at a construction site collapsed.

SUPER TYPHOON MAWAR
(TC-11W / TY 0511)
19 - 29 August
---------------------------------------
Mawar: contributed by Malaysia, is the rose--a common flowering garden
plant with bigger-sized varieties found in the highlands of
Malaysia
A. Introduction and Storm Origins
---------------------------------
Super Typhoon Mawar formed on 19 August, the same day that warnings
were first issued on Tropical Storm Guchol centred roughly 600 nm to
the east. There was no evidence of any interaction between these two
systems, largely due to their small size. Whereas the upper-level
outflow from Mawar interfered with the development of Tropical Storm
Guchol, Mawar rapidly intensified, briefly attaining super typhoon
intensity on 22 August. Mawar went on to become the first typhoon to
affect Japan in 2005.
On 18 August an area of convection persisted approximately 170 nm
southeast of Iwo Jima. It was included in JTWC's STWO, along with the
pre-Guchol disturbance, at 18/0600 UTC, when animated multi-spectral
satellite imagery depicted improving convection around a possible LLCC.
An upper-air analysis indicated that the system was located in a low to
moderate wind shear environment. Further development led to the
issuance of a TCFA at 19/0530 UTC. The first warning was issued at
19/1200 UTC on Tropical Depression 11W, located approximately 250 nm
south-southeast of Iwo Jima. The system quickly strengthened and was
soon upgraded to a 45-kt tropical storm at 19/1800 UTC. At the same
time JMA christened the tropical cyclone Mawar when their estimated MSW
(10-min avg) reached 35 kts.
B. Track and Intensity History
------------------------------
Initially embedded in a weak steering environment, Tropical Storm
Mawar began a slow northwest drift on 20 August, influenced by a
subtropical ridge situated to the northeast. Mawar rapidly intensified
into an 80-kt typhoon at 0000 UTC 21 August while passing approximately
165 nm south of Iwo Jima. Continuing slowly northwestwards, Mawar
continued to strengthen quickly, reaching a peak intensity of 130 kts at
22/0000 UTC. Mawar was a super typhoon for only six hours before a
steady weakening trend began on 22 August. However, the system remained
a major typhoon with MSW of 100-105 kts for the next two days, turning
northwards early on 24 August. Typhoon Mawar recurved northeastwards
on 25 August as it was approaching the Japanese island of Honshu and
made landfall near Tokyo, Japan, at 25/1800 UTC with MSW of 85 kts.
Moving back out to sea, the tropical cyclone weakened to below typhoon
intensity at 26/1200 UTC and transitioned into an extratropical LOW at
27/0000 UTC, the time that JTWC issued the final warning. JMA released
the last bulletin at 28/0000 UTC. The extratropical gale had weakened
into a 25-kt LOW near 38N/154W by 29/0600 UTC.
NMCC estimated a peak intensity of 110 kts while JMA and the CWB of
Taiwan estimated a maximum strength of 95 kts (all 10-min averages). A
minimum CP of 930 hPa was estimated by JMA.

WEST/2005_11W_MAWAR.gif>
C. Damage and Casualties
------------------------
Typhoon Mawar had a significant impact on Japan. Press reports
indicate that one person was killed and seven injured after the storm
came ashore on 25 August. News sources indicate that Shizuoka and
Chiba Prefectures were particularly hard hit. Thousands of households
were left without power and hundreds of families were forced to
evacuate their homes after heavy rains, up to 610 mm in some areas,
triggered flooding and landslides. Transportation was also badly
disrupted. A total of 89 flights were cancelled while Japan's bullet
train service was suspended. Offshore, Mawar temporarily forced the
suspension of vessel berthing operations at a number of oil refineries
in eastern Japan.

TROPICAL STORM GUCHOL
(TC-12W / STS 0512)
19 - 26 August
-----------------------------------------
Guchol: contributed by Micronesia, is the Yapese word for the spice
turmeric
A. Storm Origins
----------------
The disturbance which eventually developed into Tropical Storm Guchol
began as an area of convection approximately 870 nm east of Iwo Jima.
It was first mentioned in JTWC's STWO at 0930 UTC 17 August when animated
multi-spectral satellite imagery revealed increasing deep convection in
association with a weak LLCC. An upper-level analysis indicated that the
suspect area was located within a favourable low wind shear environment.
However, the deep convection remained cyclic in nature before properly
consolidating on 19 August. This development prompted the issuance of a
TCFA at 19/2130 UTC. Shortly afterward, the first warning was released
at 20/0000 UTC, locating the centre of the newly formed Tropical
Depression 12W approximately 540 nm east of Iwo Jima. Drifting slowly
westwards, the system maintained MSW of 25 to 30 kts on 20 August. It
was upgraded to a 40-kt tropical storm at 21/0000 UTC, and named Guchol
six hours later when JMA raised their MSW to 35 kts.
B. Track and Intensity History
------------------------------
On 21 August Tropical Storm Guchol turned towards the north-northwest
as it tracked along the southwest periphery of the subtropical ridge.
Animated multi-spectral satellite imagery depicted a fully-exposed LLCC
with the deep convection located to the south as a consequence of
shearing associated with the upper-level outflow from the nearby Typhoon
Mawar, located roughly 600 nm to the west. Despite this negating factor,
Guchol gradually intensified and reached its peak intensity of 60 kts,
the storm's first maximum, at 0000 UTC 22 August while located
approximately 330 nm east-northeast of Iwo Jima. Tracking north-
northwestward, Guchol began to weaken, the MSW leveling out at 50-kts
at 22/1800 UTC. Recurving sharply northeastwards, Tropical Storm Guchol
began to pull away from Typhoon Mawar on 23 August. Accelerating, the
storm slowly re-intensified, arriving at its maximum strength of 60 kts
for the second time at 24/0600 UTC. Continuing northeastward, Guchol
weakened and transformed into an extratropical cyclone at 25/0000 UTC,
JTWC issuing the last warning at this time. JMA released their final
bulletin at 25/1200 UTC. The LOW continued east-northeastward,
weakening to 25 kts by 26/1800.
Both JMA and the CWB of Taiwan estimated a peak intensity of 55 kts
while the highest MSW estimated by NMCC was 50 kts. (This is a rare
example of a case where NMCC's peak MSW is lower than JMA's.)

TYPHOON TALIM
(TC-13W / TY 0513 / ISANG)
26 August - 2 September
----------------------------------------------
Talim: contributed by the Philippines, means 'sharp' or 'cutting edge'
A. Introduction and Storm Origins
---------------------------------
Forming in the monsoon trough during late August, Talim followed a
northwestward to westward track for several days, peaking as an intense
125-kt typhoon on 29 August. Typhoon Talim was the second tropical
cyclone of typhoon intensity to strike the island of Taiwan this year,
following Super Typhoon Haitang (TC-05W) in mid-July. The storm also
had severe implications in mainland China where it caused flooding and
the loss of 110 lives.
The origins of Typhoon Talim could be traced back to an area of
convection which developed and persisted approximately 250 nm east-
northeast of Guam. It was first mentioned as a suspect area in JTWC's
STWO issued at 0600 UTC 24 August when animated multi-spectral imagery
revealed a broad LLCC associated with the disturbance. An upper-level
analysis revealed a low to moderate wind shear environment. However,
an upper-level LOW was impinging on the outflow on the northern side of
the circulation. Despite this, the potential for development of a
significant tropical cyclone was raised to 'good' at 25/2200 UTC and a
TCFA issued. The first warning was released at 26/0600 UTC when
Tropical Depression 13W was located approximately 100 nm west-southwest
of Guam. It was upgraded to a 35-kt tropical storm by both JTWC and
JMA at 27/0000 UTC, the tropical cyclone being assigned the name Talim.
B. Track and Intensity History
------------------------------
Tropical Storm Talim steadily intensified on 27 August as it moved on
a general northwestward track along the southwestern periphery of a sub-
tropical ridge. The tropical cyclone was raised to typhoon intensity
at 0600 UTC 28 August when it was located approximately 690 nm south-
east of Okinawa. At this time, PAGASA christened the tropical cyclone
Isang after the storm had entered their AOR. (Note: Even though the
name Talim was contributed to the international list by the Philippines,
PAGASA always applies a name from their alphabetical list of local
names for all systems entering their AOR.) Typhoon Talim continued
to strengthen on 28 August while moving on a more westward heading
and reached a peak intensity of 125 kts at 29/1800 UTC. After
maintaining this strength for nearly 24 hours, a weakening trend began
late on 30 August as the storm approached the island of Taiwan.
Typhoon Talim made landfall near Hualien, Taiwan, at 31/1800 UTC with a
MSW of 95 kts. From there, the cyclone crossed the Taiwan Strait and
came ashore near Fuzhou, China, around 01/0600 UTC, the same time that
it was downgraded to a 55-kt tropical storm. JTWC issued the final
warning at 01/1200 UTC while JMA continued to maintain the system as a
tropical storm, downgrading Talim to a tropical depression at 02/0600
UTC. The last statement issued by JMA was at 02/1800 UTC.
NMCC estimated a peak intensity of 130 kts while the CWB of Taiwan
estimated a peak intensity of 105 kts. JMA, PAGASA and HKO all
estimated a maximum intensity of 95 kts. The lowest CP estimated by
JMA was 925 mb. (All the Asian TCWCs MSW estimates should be understood
as representing a 10-min averaging period.)

the following link:
<http://www.tropicalcyclone2005.com/database/tc_besttracks_graphics/PACIFIC_
WEST/2005_13W_TALIM.gif>
C. Damage and Casualties
------------------------
Typhoon Talim killed at least seven people and injured 59 more as it
tracked across the island of Taiwan. Schools, financial markets and
government offices were closed and hundreds of villagers were evacuated
from mountainous regions. Transportation was badly affected. Train
services were suspended and all domestic flights were cancelled.
International air services were also delayed. Several roads were cut
off in Hsinchu County while in Taichung County, a bridge at Kukuan was
submerged by flash floods, prompting the evacuation of hundreds of
tourists. Taiwan's Formosa Petrochemical Company temporarily suspended
berthing operations at its Mai Liao refinery.
Talim's strong winds cut power supplies and downed trees while heavy
rain triggered flooding in some towns in central Taiwan. Around 1.7
million people lost power and some 48,500 households were without
running water. In the capital of Taipei, streets were abandoned as
strong winds brought down trees and blew debris against buildings and
homes.
News reports indicate that Typhoon Talim left at least 110 people dead
in eastern mainland China, 40 of those believed to have perished in
landslides in Anhui province. More than 150,000 people were evacuated,
and thousands of homes were damaged or destroyed.

(TC-14W / TY 0514 / JOLINA)
29 August - 11 September
-----------------------------------------------
Nabi: contributed by South Korea, means 'butterfly'
A. Introduction and Storm Origins
---------------------------------
The third super typhoon of the year, Nabi followed a classic
recurvature path, passing through the Marianas on 31 August, ultimately
becoming the second tropical cyclone to make landfall on Japanese soil
in 2005.
Super Typhoon Nabi began as a persistent area of convection
approximately 560 nm east of Guam. It was first mentioned in a STWO
issued by JTWC at 1900 UTC 28 August when enhanced infrared animations
and water vapor satellite imagery revealed a large region of deep
convection associated with the disturbance. However, a 28/1244 UTC
TRMM microwave pass indicated that the deep convection was located
mainly within the western and southern quadrants. The system quickly
developed as it moved slowly west to west-southwestward through a
moderate wind shear environment. A TCFA was issued at 29/0200 UTC and
was soon replaced by the first warning at 29/0600 UTC. At this time
the centre of Tropical Depression 14W was located approximately 520 nm
east-northeast of Guam and tracking towards the west at around 6 kts
along the southern periphery of a mid-level steering ridge located
southeast of Japan. TD-14W steadily intensified and was upgraded to a
40-kt tropical storm at 29/1800 UTC, the storm having already been
named Nabi six hours earlier after JMA had raised their 10-min avg MSW
to 40-kts.
B. Track and Intensity History
------------------------------
Tropical Storm Nabi continued to strengthen as it tracked westward
towards the Marianas and was upgraded to Typhoon Nabi at 1200 UTC
30 August while located approximately 130 nm east-southeast of Saipan.
Turning onto a west-northwesterly course, Nabi continued to intensify
while passing through the Marianas on 31 August, the centre passing
35 nm northeast of Saipan at 31/1200 UTC. Intensification continued,
culminating in the storm's reaching its peak intensity of 140 kts at
01/1800 UTC. Some weakening occurred but Nabi maintained super typhoon
intensity through 2 September as it entered the far northeast portion
of PAGASA's AOR. The Filipino name for this tropical cyclone was
Jolina.
Moving northwestward Nabi was downgraded to a typhoon early on
3 September, and after weakening further, the MSW leveled out at 105 kts
later that day. An approaching mid-level trough exiting eastern China
caused the steering ridge to retreat eastwards, inducing Typhoon Nabi
to turn to a progressively northward path. In the meantime, Nabi
re-intensified and reached a secondary peak of 115 kts at 0000 UTC
5 September while located approximately 310 nm south-southeast of Sasebo,
Japan. Accelerating northwards, Typhoon Nabi made landfall on the
Japanese island of Kyushu at 06/0000 UTC with a MSW of 90 kts. The
tropical cyclone then crossed southwestern Japan on 6 September and
recurved into the Sea of Japan, completing extratropical transition at
06/1800 UTC, the time that JTWC issued the final warning. JMA
downgraded Nabi to a tropical storm at 07/0000 UTC and maintained this
intensity until the issuance of their last bulletin at 08/0600 UTC,
shortly after the cyclone had crossed northern Hokkaido and was
speeding eastward across the North Pacific. JMA carried the
extratropical remnants of Nabi in their high seas warnings through
11/1800 UTC. The extratropical LOW had by this time turned northward
and passed through the Aleutian Islands and was a 35-kt gale situated
in the central Bering Sea.
NMCC estimated a peak intensity of 120 kts while the CWB of Taiwan
estimated a MSW of 105 kts (10-min averages). The maximum strength per
PAGASA warnings during the time that Nabi/Jolina was tracking through
that agency's AOR was 95 kts. The highest peak intensity estimated by
JMA was 95 kts and the lowest CP was 925 mb. HKO did not issue any
warnings on this system.

C. Damage and Casualties
------------------------
Typhoon Nabi had a significant impact on southern Japan. According to
press reports, 32 people were killed and 140 injured. At least 270,000
households were without electricity and around 10,000 buildings were
damaged.
Transportation was badly disrupted by the heavy rains and strong
winds. Hundreds of flights and ferries in and out of Kyushu and Shikoku
were cancelled while all the West Japan Railway Company's train services
were suspended.
Industry was also badly hit. The car assembly plants in southwestern
Japan at Honda Motor Company, Toyota Motor Corporation, Nissan Motor
Company and Mazda Motor Corporation were temporarily halted. Mitsubishi
Heavy Industries closed ship building plants in Nagasaki, Yamaguchi and
Hiroshima while the oil refiner Kyushu Oil Company, Japan Energy and
Idemitsu Kosan Company also halted operations.
Torrential rains caused widespread flooding. Parts of Miyazaki
received more than 1,000 mm (40 inches) of rain while 800 mm (32 inches)
was recorded in Kagoshima and Oita. Tokyo and surrounding areas also
experienced heavy rainfall. More than 230 mm (9 inches) fell in the
capital city in one hour.
The General Insurance Association of Japan estimated overall insured
losses of 58.8 billion yen (535 million US dollars), the tenth most
expensive typhoon on record.
Typhoon Nabi also affected South Korea. In Busan, strong winds blew
down dozens of signboards and uprooted trees. Up to 152 mm (6 inches)
of rain was recorded in the city. A Vietnamese cargo ship, the Long
Xuyen, ran aground in the port city of Pohang. Press reports indicated
that five people were missing but there appears to have been no deaths.
There are no reports of damages or casualties in the Marianas. Saipan
endured sustained winds of up to 65 kts while nearby Guam experienced
tropical storm force winds and 76 mm (3 inches) of rain. According to
some information sent by Huang Chunliang, the NWS office at Agana, Guam,
(13.5N/144.8E) recorded 118.4 mm (4.66 inches) during the 24 hours
between 30/1200 and 31/1200 UTC.

SPECIAL FEATURE - SOURCES OF TROPICAL CYCLONE INFORMATION
The purpose of this section is to list some websites where many and
varied types of tropical cyclone information are archived. Many readers
will know about these already, but for the benefit of those who don't,
I wanted to include them.
(1) Aircraft Reconnaissance Information
---------------------------------------
Various types of messages from reconnaissance aircraft may be
retrieved from the following FTP site:
<ftp://ftp.nhc.noaa.gov/pub/products/nhc/recon/>
Information regarding how to interpret the coded reconnaissance
messages may be found at the following URL:
<http://www.nhc.noaa.gov/reconlist.shtml>
Links are also included to websites with further information about the
U. S. Air Force 53rd Weather Reconnaissance Squadron and the NOAA Air-
craft Operations Center.
(2) Archived Advisories
-----------------------
All the advisory products (public advisories, forecast/advisories,
strike probabilities, discussions, various graphics) issued by TPC/NHC
are archived on TPC's website. For the current year (using 2004 as an
example), the archived products can be found at:
<http://www.nhc.noaa.gov/archive/2004/index.shtml>
Links to tropical products archives for earlier years are available at
the following URL:
<http://www.nhc.noaa.gov/pastall.shtml>
JTWC warnings for past storms are archived on the NRL Monterry website:
<http://www.nrlmry.navy.mil/tc_pages/tc_home.html>
On the NRL site, the link to past years can be found in the upper left
corner of the screen.
I am not aware at the moment of any other TCWC which archives all
its tropical cyclone warning/advisory products for public access, but
if I learn of any, I will add them to this list.
(3) Satellite Imagery
---------------------
Satellite images of tropical cyclones in various sensor bands are
available on the NRL Monterrey and University of Wisconsin websites,
courtesy of Jeff Hawkins and Chris Velden and their associates. The
links are:
<http://www.nrlmry.navy.mil/tc_pages/tc_home.html>
<http://cimss.ssec.wisc.edu/tropic/tropic.html>
On the NRL site, the link to past years can be found in the upper left
corner of the screen. For the CIMSS site, a link to data archives is
located in the lower left portion of the screen.
Additional tropical satellite imagery, along with looping ability for
composite microwave imagery for the Western Hemisphere north of the
equator, can be found at:
(1) For the Eastern North Pacific:
<http://www.ssd.noaa.gov/PS/TROP/trop-epac.html>
(2) For the Atlantic, Gulf of Mexico and Caribbean Sea:
<http://www.ssd.noaa.gov/PS/TROP/trop-atl.html>
I'm sure there are other sites with available imagery available, and
as I learn of them, I will add the links to this list.
*************************************************************************
EXTRA FEATURE
In order to shorten the amount of typing in preparing the narrative
material, I have been in the habit of freely using abbreviations and
acronyms. I have tried to define most of these with the first usage
in a given summary, but I may have missed one now and then. Most of
these are probably understood by a majority of readers but perhaps a
few aren't clear to some. To remedy this I developed a Glossary of
Abbreviations and Acronyms which I first included in the August, 1998
summary. I don't normally include the Glossary in most months in
order to help keep them from being too long. If anyone would like to
receive a copy of the Glossary, please e-mail me and I'll be happy
to send them a copy.
*************************************************************************
AUTHOR'S NOTE: This summary should be considered a very preliminary
overview of the tropical cyclones that occur in each month. The cyclone
tracks (provided separately) will generally be based upon operational
warnings issued by the various tropical cyclone warning centers. The
information contained therein may differ somewhat from the tracking and
intensity information obtained from a "best-track" file which is based
on a detailed post-seasonal analysis of all available data. Information
on where to find official "best-track" files from the various warning
centers will be passed along from time to time.
The track files are not being sent via e-mail. They can be retrieved
from the archive sites listed below. (Note: I do have a limited e-mail
distribution list for the track files. If anyone wishes to receive
these via e-mail, please send me a message.)
Both the summaries and the track files are standard text files
created in DOS editor. Download to disk and use a viewer such as
Notepad or DOS editor to view the files.
The first summary in this series covered the month of October,
1997. Back issues can be obtained from the following websites

<ftp://ftp.aoml.noaa.gov/hrd/pub/landsea/padgett/>
<http://www.tropicalcyclone2005.com/>
Another website where much information about tropical cyclones may
be found is the website for the UK Meteorological Office. Their site
contains a lot of statistical information about tropical cyclones
globally on a monthly basis. The URL is:
<http://www.metoffice.gov.uk/weather/tropicalcyclone>
TROPICAL CYCLONE REPORTS AVAILABLE
JTWC now has available on its website the Annual Tropical Cyclone
Report (ATCR) for 2004 (2003-2004 season for the Southern Hemisphere).
ATCRs for earlier years are available also.
The URL is: <http://199.10.200.33/jtwc.html>
Also, TPC/NHC has available on its webpage nice "technicolor"
tracking charts for the 2004 Atlantic and Eastern North Pacific
tropical cyclones; also, storm reports for all the 2004 Atlantic
and Eastern North Pacific cyclones are now available, as well as
track charts and reports on storms from earlier years.
The URL is: <http://www.nhc.noaa.gov>
A special thanks to Michael Bath of McLeans Ridges, New South Wales,
Australia, for assisting me with proofreading the summaries.
