10. Super Typhoon NABI (Jolina/14w) 
>> August 29-September 11, 2005
Nabi: contributed by South Korea, means 'butterfly'
A. Introduction & 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 & 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 & 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.
