Typhoon Bart,known in the Philippines as Typhoon Oniang,was a powerful and destructive typhoon that occurred during the 1999 Pacific typhoon season. It was the only super typhoon of that year. Bart reached "super typhoon" status on September 22,when it grew to comprise winds containing a force of 260 km/h (160 mph).
Bart killed at least two people on the island of Okinawa and brought over 710 millimeters (28 in) of rain to the island. Kadena Air Base was badly damaged by the typhoon,with over $5 million of damage sustained by the base. Heavy flooding and landslides led to a death toll of 30 and over 1,000 injuries in Japan. Over 800,000 homes lost power,whilst 80,000 were damaged in the aftermath of the storm. The worst damage occurred in Kumamoto Prefecture on the island of Kyūshū,where 16 people died and over 45,000 homes were damaged.
On September 14, an area of disturbed weather formed within the active monsoon trough south of Okinawa. The disturbance began to develop a low-pressure area, but it quickly merged with another collection of thunderstorms to the north. The following day, a new system developed and moved west-southwest. It only slowly organized given suppressed outflow from a nearby tropical upper-tropospheric trough and a lack of cyclonic rotation. [1] [2] The developing system drifted eastward and acquired a surface circulation, which prompted the Joint Typhoon Warning Center (JTWC) to issue a Tropical Cyclone Formation Alert at 03:00 UTC on September 17. [1] This came just three hours after the principal agency in the West Pacific, the Japan Meteorological Agency (JMA), first began monitoring the system. [3] At 15:00 UTC on September 17, the JTWC issued their first advisory on Tropical Depression 24W. [2] The suppressive effects of the trough initially stripped the center of deep atmospheric convection, but as this trough moved northwest and weakened, the surrounding environment began to improve. Both the JMA and JTWC upgraded the depression to Tropical Storm Bart at 00:00 UTC on September 19, at which time the Philippines-based organization PAGASA began warning on Tropical Depression Oniang. Six hours later, PAGASA upgraded the depression to a tropical storm as well. [1]
Some northerly wind shear continued to affect Bart as it moved along a northwesterly course between two subtropical ridges on either side of the cyclone. However, deep convection, originally confined to the southern semicircle of the system, began to wrap around the eastern quadrant as an anticyclone developed aloft. This improving presentation on weather satellite soon yielded the development of an 19 km (12 mi)-diameter eye around 00:00 UTC on September 20, prompting the JTWC to upgrade Bart to a typhoon at this time. While Bart attained increased in intensity, one of the subtropical ridges to its north weakened, causing the system to become nearly stationary while it was positioned about 370 km (230 mi) southwest of Okinawa. [1] A climatological rate of strengthening ensued as the cyclone slowly began to move northward late on September 21, and Bart reached winds of 240 km/h (150 mph) at 18:00 UTC that day, making it a super typhoon based on JTWC classification. By 06:00 UTC on September 22, [2] with an eye that had grown to 39 km (24 mi) and excellent outflow in all directions, [1] Bart attained peak one-minute sustained winds of 260 km/h (160 mph), equivalent to a Category 5 hurricane on the Saffir–Simpson scale. [2] The JMA, meanwhile, recorded ten-minute sustained winds of 165 km/h (103 mph) as the system passed only 75 km (47 mi) west of Okinawa. [1] [3]
Later on September 22, the potent cyclone began to feel the effects of dry air entrainment into its circulation. The eye diameter fell to 14 km (8.7 mi) and continued to shrink, and soon, Bart began to undergo an eyewall replacement cycle as it fell below super typhoon intensity. An approaching trough in the mid-latitudes and an intensifying ridge to its northeast caused the cyclone to accelerate in that direction, while microwave imagery depicted a newly formed, symmetric 74 km (46 mi) eye. The system made landfall near Omuta in Kyushu, the southwesternmost island of Japan, and it soon crossed Honshu. This movement brought Bart into the Sea of Japan to the west of Hiroshima by 00:00 UTC on September 24, around which time it further decayed into a tropical storm. The effects of land were exacerbated by an increase in strong southwesterly wind shear as Bart continued to accelerate northeastward. [1] The JTWC declared the system an extratropical cyclone at 15:00 UTC on September 24, [2] and the JMA followed suit over subsequent hours as the non-tropical low moved into the Sea of Okhotsk east of northern Hokkaido. [1] The remnants of Bart continued into the North Pacific. [2]
As Bart overspread much of Japan and combined with a cold front, [4] it yielded numerous reports of rainfall accumulations in excess of 510 mm (20 in). The highest recorded value was 1,180 mm (46 in) in Funato, located in the Kōchi Prefecture. [5] Heavy rains caused flooding, which was exacerbated by swollen rivers. [6] The cyclone also produced numerous tropical storm- or typhoon-force winds across the island, peaking at 151 km/h (94 mph) across Seto in the Ehime Prefecture. [5] The inclement weather caused over 245 landslides and damaged or destroyed buildings. [7] [8] Strong winds downed numerous trees, contributing to additional damage to structures. [9] Ferry service connecting the various prefectures was cancelled, [10] airline flights were halted, train service was severely disrupted, large ships moored along the coast were evacuated, and many schools were closed. [11] Numerous people were evacuated throughout the region. [12] In total, Bart caused 36 fatalities, [5] injured over 1,314 people, flooded 18,498 homes, [2] and left 813,000 households without power. [13]
In Okinawa, downed trees, flooded roads, and overturned cars were prevalent, forcing the U.S. military to restrict personnel and their families to their homes. [7] [14] In the Gifu Prefecture, landslides collapsed roads, leading to eight deaths and eight injuries. [15] In the Yamaguchi Prefecture, the collapse of a wall in Yamaguchi City killed two people, while another person died from strong winds in Ohata Town. [16] The storm shuttered production units at a Seibu Oil company. [17] In the Hiroshima Prefecture, two large cranes under construction collapsed and hit a nearby office, killing three employees. Two more people died in Shimamachi and Tomoda. Along the coastline, a pier suffered structural damage, and thousands of oyster farming rafts were damaged. [16] The Itsukushima Shrine, one of Japan's most famous Shinto shrines and a member of the United Nation's World Cultural Heritage List, was damaged. [17] Three people were killed in the Fukuoka Prefecture, [18] where firefighters traveled by rubber boat to search for missing people. In the Kumamoto Prefecture, more than 30 police officers were sent to Shiranui, [19] conducting search and rescue in homes that were flooded to their rooftops by a storm surge up to 3.5 m (11 ft) that funneled into Yatsushiro Sea. The surge coincided with the peak timing of the spring tide, [20] killing 13 people. Another three people died from head injuries caused by flying debris. Forty-three municipalities in the prefecture set up disaster response headquarters. [21] The trade office was closed and suffered minor damage, but it was expected to swiftly reopen following the passage of the storm. [22] In the Kagoshima Prefecture, strong winds downed a steel tower which contributed to power and water outages through September 28. [23] In the Miyazaki Prefecture, the collapse of a road caused a man to plunge into the Gokase River and die. [24]
Bart also spawned a tornado outbreak. The first tornado, rated F0–F1 in strength, occurred in the Nagasaki Prefecture late on September 23. This was succeeded by tornadoes of F1 and F2 intensity in the Kochi and Yamaguchi prefectures, respectively. The four other tornadoes occurred in the Aichi Prefecture; two were rated F1, one was rated F2, and one was rated F3. The majority of damage during the outbreak was associated with the F3 tornado which grew up to 550 m (600 yd) and tracked for 18 km (11 mi). The tornado completely demolished 40 houses and damaged 309 others, resulting in 415 injuries. The F2 in the Aichi Prefecture also destroyed a house and damaged two others; it caused 38 injuries. The F2 in the Yamaguchi Prefecture injured 13 people. [25] These tornadoes occurred in the right front quadrant of the typhoon, a historically favorable quadrant for tornadic activity. The presence of high convective available potential energy and strong wind shear favored the development of supercell thunderstorms across Japan on September 23–24. [26]
Typhoon Vera, also known as the Isewan Typhoon, was an exceptionally intense tropical cyclone that struck Japan in September 1959, becoming the strongest and deadliest typhoon on record to make landfall on the country, as well as the only one to do so as a Category 5 equivalent storm. The storm's intensity resulted in catastrophic damage of unparalleled severity and extent, and was a major setback to the Japanese economy, which was still recovering from World War II. In the aftermath of Vera, Japan's disaster management and relief systems were significantly reformed, and the typhoon's effects would set a benchmark for future storms striking the country.
Typhoon Babe, known in Japan as Okinoerabu Typhoon, and in the Philippines as Typhoon Miling, was regarded as "the worst typhoon to threaten Japan in 18 years." Developing as a tropical depression on September 2, Babe initially tracked west-northwestward as it intensified. On September 5, an abrupt shift in steering currents caused the system to turn north-northwestward. Early on September 6, the system intensified into a typhoon. Over the following two days, Babe quickly intensified, ultimately attaining its peak intensity early on September 8 with winds of 240 km/h (150 mph) and a barometric pressure of 905 mbar. Not long after reaching this strength, another shift in the steering patterns caused the typhoon to execute a prolonged counter-clockwise arc, causing it to track through the Ryukyu Islands southwest of Japan, as it interacted with a low pressure originating from the Korean Peninsula. During this time, the system gradually weakened and eventually it made landfall near Shanghai, China on September 11 as a minimal typhoon before dissipating inland the following day. Coincidentally, Typhoon Babe and Atlantic Hurricane Babe existed at the same time from September 3–9.
Typhoon Xangsane, known in the Philippines as Typhoon Reming, was a typhoon that made landfall in the Philippines and Taiwan. The 30th named storm and 12th typhoon of the 2000 Pacific typhoon season. Xangsane made landfall in southern Luzon in the Philippines, on October 27. The storm then turned north, heading northeastward over the South China Sea. On October 29, Xangsane reached its peak intensity, with 10-minute sustained winds of 140 km/h (87 mph), 1-minute sustained winds of 165 km/h (103 mph) and a minimum barometric pressure of 960 hPa (28 inHg). The storm paralleled the eastern coast of Taiwan, the next day. After leaving the vicinity of Taiwan, Xangsane started to weaken as it continued to move northeastward over the East China Sea and subsequently transitioned to an extratropical cyclone, midway between the eastern coast of China and the northern Okinawa Islands, on November 1. Xangsane was responsible for 187 casualties, including 83 possibly indirectly from the crash of Singapore Airlines Flight 006 on October 31, 2000.
Typhoon Jangmi, known in the Philippines as Super Typhoon Ofel, was the most intense tropical cyclone in the Northwest Pacific Ocean during the 2000s, tied with Nida in 2009, and the most intense tropical cyclone worldwide in 2008. Jangmi, which means rose in Korean, formed in a low pressure area south of Guam on September 22. After undergoing serious consolidating with convective banding, the low pressure area was upgraded to a Joint Typhoon Warning Center late the same data. Undergoing the same process, the storm developed into a tropical storm on September 24. Undergoing rapid deepening on September 26–27, the storm, now a Super Typhoon entered the Philippine Area of Responsibility, and was named Ofel. The next day, Jangmi made impact in Taiwan, thousands were evacuated, rainfall, up to 994mm were recorded, and thousands of acres of farmland were destroyed. Jangmi was significantly weakened as it interacted with Taiwan, as being downgraded to tropical storm status after leaving Taiwan on September 29. After undergoing an extratropical transition, Jangmi became a remnant low on October 1. After slowly moving eastward, until finally dissipating near Iwo Jima on October 5.
Typhoon Nabi, known in the Philippines as Super Typhoon Jolina, was a powerful typhoon that struck southwestern Japan in September 2005. The 14th named storm of the 2005 Pacific typhoon season, Nabi formed on August 29 to the east of the Northern Mariana Islands. It moved westward and passed about 55 km (34 mi) north of Saipan on August 31 as an intensifying typhoon. On the next day, the Joint Typhoon Warning Center upgraded the storm to super typhoon status, with winds equivalent to that of a Category 5 hurricane on the Saffir–Simpson Hurricane Scale. The Japan Meteorological Agency estimated peak ten-minute winds of 175 km/h (109 mph) on September 2. Nabi weakened while curving to the north, striking the Japanese island of Kyushu on September 6. After brushing South Korea, the storm turned to the northeast, passing over Hokkaido before becoming extratropical on September 8, before dissipating on September 12.
Typhoon Tingting was a destructive tropical cyclone that produced record-breaking rains in Guam. The eighth named storm of the 2004 Pacific typhoon season, Tingting originated from a tropical depression over the open waters of the western Pacific Ocean. The storm gradually intensified as it traveled northwest, becoming a typhoon on June 28 and reaching its peak the following day while passing through the Mariana Islands. After maintaining typhoon intensity for three days, a combination of dry air and cooler sea surface temperatures caused the storm to weaken as it traveled northward. On July 1, the storm passed by the Bonin Islands, off the coast of Japan, before moving out to sea. By July 4, Tinting had transitioned into an extratropical cyclone. The remnants were last reported by the Japan Meteorological Agency, the Regional Specialized Meteorological Center for the western Pacific basin, near the International Date Line on July 13.
Typhoon Maria was a minimal typhoon which brushed the southeastern coast of Japan during early August 2006. The seventh named storm of the 2006 Pacific typhoon season, Maria formed out of a tropical depression over the open waters of the western Pacific Ocean. On August 5, the Japan Meteorological Agency (JMA) classified the depression as a tropical storm while the Joint Typhoon Warning Center (JTWC) kept it as a depression. The storm quickly strengthened into a typhoon the next day, reaching its peak intensity with winds of 130 km/h early on August 6. The storm gradually weakened as it began to recurve, causing it to parallel the southeastern coast of Japan. On August 9, Maria weakened into a tropical depression and later into an extratropical cyclone before dissipating on August 15. Maria had only minor effects in Japan, mainly heavy rains which were estimated to have peaked over 400 mm (15.7 in) on the Izu Peninsula. One person was killed after being struck by lightning and six others were injured.
Typhoon Conson, known in the Philippines as Typhoon Frank, was the first of the record ten typhoons to impact Japan during the 2004 Pacific typhoon season. Developing out of a tropical depression near the northern Philippines in early June, Conson slowly traveled towards the north. Gradually strengthening, the storm reached typhoon status late on June 7 according to the Joint Typhoon Warning Center and several hours later according to the Japan Meteorological Agency. After turning towards the northeast, the typhoon brushed Taiwan and reached its peak intensity with 10-minute sustained winds of 150 km/h (90 mph) on June 9. After reaching its peak, Conson gradually weakened, passing through Okinawa before being downgraded to a tropical storm the next day. On June 11, the storm made landfall as a minimal tropical storm in the Kōchi Prefecture just before becoming extratropical. The extratropical remnants continued towards the northeast and were last mentioned on June 14 crossing the International Date Line.
Typhoon Fred was a powerful tropical cyclone that caused extensive damage in southeastern China in mid-August 1994. Regarded as the worst typhoon to affect Zhejiang in 160 years, it originated as an area of disturbed weather over the open West Pacific on August 13. The system moved west-southwest and developed into a tropical depression on August 14. Early on August 15, it intensified into a tropical storm. Fred intensified at a steady rate over the course of several days while moving toward the west. The storm intensified into a typhoon on August 16 and into a super typhoon three days later. Late on August 19, the Japan Meteorological Agency (JMA), the principal organization in the West Pacific, estimated 10-minute sustained winds of 185 km/h (115 mph). The Joint Typhoon Warning Center (JTWC), meanwhile, assessed 1-minute sustained winds of 240 km/h (150 mph). After peaking in intensity, Fred veered to the north of Taiwan and struck the China mainland near Wenzhou early on August 21. The system degraded once inland and dissipated near Wuhan on August 22.
Severe Tropical Storm Linfa, known in the Philippines as Tropical Storm Chedeng, brought deadly flooding to areas of the Philippines and Japan in May and June 2003. The fourth named storm within the northwestern Pacific that year, Linfa developed as a tropical depression just off the western coast of Luzon on May 25. The disturbance quickly intensified to reach tropical storm intensity a few hours after cyclogenesis. However, intensification leveled off as Linfa executed a small clockwise loop before a subsequent landfall on Luzon on May 27. Due to land interaction the storm temporarily weakened and decoupled before reforming in the Philippine Sea. Afterwards Linfa began reintensifying and reached its peak intensity on May 29 with maximum sustained winds of 100 km/h (65 mph) and a barometric pressure of 980 mbar. Following its peak the tropical storm began to deteriorate and transitioned into an extratropical cyclone on May 30; these extratropical remnants continued to track northward through Japan before dissipating in the Sea of Okhotsk on June 4.
Typhoon Flo, known in the Philippines as Typhoon Norming, was a long-lived typhoon that brought destruction to much of Japan during September 1990. Flo originated from an area of convection that first formed to the southeast of the Marshall Islands on September 7. Five days later, the disturbance obtained tropical depression status, and on September 13, intensified into a tropical storm. Tracking west-northwest as it rounded a subtropical ridge, Flo slowly deepened, and on September 15, became a typhoon. After developing an eye, Flo began to rapidly intensify, and on September 17, Flo attained peak intensity. Shortly thereafter, the typhoon began to recurve to the northeast towards Honshu in response to deepening troughs to the northwest and north of the system, which resulted in a weakening trend due to increased vertical wind shear despite remaining over warm water. On September 19, Flo made landfall on southern Honshu, becoming the first typhoon to hit the Kii Peninsula in 11 years, and thereafter started to transition into an extratropical cyclone. The extratropical remnants of Flo were last noted on the morning of September 22.
Typhoon Abby, known in the Philippines as Typhoon Diding, was an extremely powerful tropical cyclone which was the second typhoon to strike Japan within a span of a few days in August 1983. First noted southeast of Guam on July 31, development of this system was initially slow to occur; it was first classified on August 5, and was upgraded into a tropical storm the next day. Intensification was rapid as Abby slowly recurved northward on August 7 and 8. After reaching peak intensity with winds of 140 mph (225 km/h) early on August 9, Abby slowly weakened, though the storm briefly re-intensified on August 11. By August 14, winds had diminished to 100 mph (160 km/h). Abby finally weakened back into a tropical storm on August 17 not long after making landfall in Japan. The following day, Abby completed the transition to an extratropical cyclone after moving through central Japan. However, meteorologists continued monitoring the storm for six more days.
Typhoon Yancy, known in the Philippines as Typhoon Tasing, was one of the costliest and most intense tropical cyclones to strike Japan on record. Yancy was the sixth typhoon of the annual typhoon season and sixth tropical cyclone overall to impact Japan that year. Developing out of an area of disturbed weather in the open northwest Pacific on August 29, 1993, the precursor to Yancy tracked westward and quickly intensified to reach tropical storm strength on August 30. Just two days later, the tropical storm reached typhoon intensity as it recurved towards the northeast. A period of rapid intensification followed, allowing Yancy to quickly reach super typhoon intensity. The strong tropical cyclone reached peak intensity on September 2 with maximum sustained winds of 175 km/h (109 mph). The following day Yancy made its first landfall on Iōjima at nearly the same strength; over the course of the day the typhoon would make three subsequent landfalls on Japanese islands. Land interaction forced the tropical cyclone to weaken, and after its final landfall on Hiroshima Prefecture, Yancy weakened below typhoon intensity. After emerging into the Sea of Japan, Yancy transitioned into an extratropical cyclone; these remnants persisted as they meandered in the sea before dissipating completely on September 7.
Typhoon Tokage, known in the Philippines as Typhoon Siony, was the deadliest typhoon to strike Japan since Typhoon Bess in 1982. The twenty-third storm to be named using an international list of names during the 2004 Pacific typhoon season, Tokage was the last of three typhoons to impact Japan from late-September to mid-October 2004. Typhoon Tokage began as a tropical depression near the Northern Mariana Islands on October 10. With very warm waters, the system started to undergo a rapid deepening phase early on October 13 and reached its peak strength on the 17th. Tokage made landfall over Japan on October 20, just before becoming extratropical.
Typhoon Ma-on, known in the Philippines as Typhoon Rolly, was a powerful typhoon that produced record breaking wind gusts across the Tokyo Metropolitan Area during October 2004. The twenty-second named storm of the 2004 Pacific typhoon season, Ma-on was the second of three consecutive storms to hit Japan during the period between late-September to mid-October 2004.
Typhoon Della, known in Japan as the 3rd Miyakojima Typhoon and in the Philippines as Typhoon Maring, was a typhoon that struck Miyakojima of Ryukyu Islands and Kyūshū Island in September 1968.
Typhoon Kent was a strong mid-season typhoon that struck southern Japan during August 1992. An area of convection developed east of the International Date Line. Tracking west-northwestward, a tropical depression developed on August 5, and the next day, intensified into a tropical storm. On August 8, increased vertical wind shear caused convection to decrease, although Kent strengthened into a typhoon on the next day. An eye then appeared as conditions aloft became more conducive, and on August 11, Kent attained its peak intensity. Under the influence of a subtropical ridge located to its north, the typhoon initially continued to move west-northwestward before turning towards Kyushu. The storm steadily weakened prior to making landfall on August 18 just below typhoon intensity. The mountainous terrain of Japan accelerated the weakening trend, and on August 20, Kent dissipated.
Typhoon Georgia was one of the more impactful typhoons that struck Japan, as well as one of the few observed tropical cyclones that made direct landfall in Russia as a tropical storm. A low pressure system formed in the vicinity of Guam on August 10 which formed Tropical Depression Fran, and a new low-level center formed from a fracture of a trough that split newly formed tropical depression in the midnight of August 12. The newly formed low level center was classified as a tropical storm and was named Georgia hours later by the Joint Typhoon Warning Center. The new tropical storm was tracked by Japan Meteorological Agency shortly afterwards and Georgia rapidly intensified into a typhoon. On the next day, Georgia further intensified after passing Chichi Jima and reached peak sustained winds of 110 knots (57 m/s) while quickly accelerating in the north-northwest direction before striking Chūbu region in Japan on evening of the same day as a weakening typhoon. After emerging on the Sea of Japan as a tropical storm on August 14, Georgia made landfall in Soviet Union as a tropical storm at the afternoon of the same day, before transforming into an extratropical storm quickly after landfall. Remnants of Georgia was last noted on Heilongjiang, China on August 16.
Typhoon Dinah was a tropical cyclone that brought heavy damages to Japan, while leaving 65 fatalities and 70 to be missing, all in that country alone. It is also one of the disasters that happened in the country during the Showa 27 era. The second typhoon of the 1952 Pacific typhoon season, Dinah was first mentioned in weather maps as a tropical depression to the east of Visayas. It gradually organized, becoming a tropical storm on June 21 as it skirted the northeastern Philippines, with the Fleet Weather Center naming it Dinah. It strengthened further to a minimal typhoon as it moved through the Nansei Islands on June 22, before reaching its peak intensity of 140 km/h, as estimated by the Fleet Center. It then weakened shortly, before passing near Shikoku on the next day, then making landfall through the southern part of the Kii Peninsula before gradually weakened further and started to undergo extratropical transition as it moved out of the country on June 24. It then became fully extratropical on the next day.
Typhoon Rex, known in the Philippines as Typhoon Deling, was the 4th named storm in 1998 Pacific typhoon season, and it approached Japan in late August. Rex did not made landfall in Japan, but 22 people were killed in heavy rains in some parts of Japan due to the weather front and Rex.
