Typhoon Abe, known as Typhoon Heling in the Philippines, was the fourteenth named storm of 1990 Pacific typhoon season. Forming on August 23 from a tropical disturbance, the depression which would eventually develop into Typhoon Abe initially tracked in a steady west-northwestward direction. As a result of an intense monsoon surge, Abe's trajectory briefly changed to an eastward then northward path before returning to its original track. Abe only intensified by a small amount between 00:00 UTC August 24 and 06:00 UTC August 27 due to the disruptive effects of the surge, and on August 30, Abe peaked in intensity as a Category 2-equivalent typhoon on the Saffir–Simpson hurricane wind scale. After peaking in intensity, Abe crossed the Ryukyu Islands and the East China Sea, making landfall in China where it affected the provinces of Zhejiang and Jiangsu before entering the Yellow Sea, crossing South Korea, and finally transitioning into an extratropical cyclone. Typhoon Abe killed 108–195 people after it caused flooding and landslides in the Philippines and Taiwan, ravaged coastal areas of China, and brought high waves to Japan.〔 Abe, which is responsible for killing 108 in China, affected half of Zhejiang's land area and a fourth of its population, leaving thousands homeless and causing ¥3.5 billion yuan (RMB, $741.5–743 million USD) to be lost in damages.〔〔〔 〕 Additional damage and one fatality occurred in Okinawa Prefecture in Japan, where at least ¥890 million yen (JPY, $6 million USD) in damage was caused.〔 ==Meteorological history== The tropical disturbance which would eventually intensify to become Typhoon Abe was first noted by the Joint Typhoon Warning Center (JTWC) in a Significant Tropical Weather Advisory as an area of persistent atmospheric convection on August 23 at 01:00 UTC. Located near the end of what the JTWC considered to be "an active monsoon trough", the initial minimum sea-level pressure was estimated to be approximately . Following this mention, the disturbance tracked in a mostly west-northwestward direction, traveling beneath a subtropical ridge, with a Tropical Cyclone Formation Alert being issued at 06:00 UTC based on the improving state of the low.〔 Following an increase in the storm's central convection, the JTWC determined at 00:00 UTC August 24 that it had intensified into a tropical storm which it assigned the designation ''15W'', and the Japan Meteorological Agency (JMA) began to monitor the system six hours later.〔 The JMA upgraded the system to a tropical storm on its scale at 00:00 UTC August 25, and by the time twelve hours had passed, a strong surge in the monsoon westerlies had started to develop to the south of the storm's convective area, slowing its westward movement. After enhanced convection associated with the surge on the east side of Abe's main convective cloud mass wrapped around the north, the storm's center of circulation reorganized to the north between the competing convective masses. At 06:00 UTC August 27, the JMA upgraded Abe to a severe tropical storm with winds of 95 km/h (60 mph),〔 and as a ragged eye developed in the storm, the JTWC upgraded Abe to typhoon status six hours later.〔 Late on August 28, the JMA upgraded Abe to a typhoon on its scale, with ten-minute sustained winds of .〔 Following the monsoon surge, Abe returned to its original west-northwestward track, further intensifying to become a Category 2-equivalent typhoon at 12:00 UTC on August 29. A weakness appeared in the subtropical ridge in association with a short-wave trough, and Typhoon Abe recurved through this weakness, taking it along the coast of China.〔 Prior to making landfall, Abe attained a minimum atmospheric pressure of 955 millibars (hPa; 28.20 inHg) on August 29 at 18:00 UTC as determined by the JMA.〔 It was found by the JTWC that Abe's one-minute sustained winds peaked at 165 km/h (105 mph) at 00:00 UTC August 30,〔 and the JMA determined that its ten-minute sustained winds peaked at 140 km/h (85 mph) at 18:00 UTC on August 29.〔 As a direct result of this interaction with land, Abe weakened to a tropical storm at 12:00 UTC on August 31, entering the Yellow Sea and crossing South Korea in the 30 hours that followed. It was determined at 18:00 UTC on September 1 that the storm had transitioned into an extratropical cyclone.〔 The JTWC ceased tracking the system at 06:00 UTC September 2,〔 and the JMA followed suit 36 hours later.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Typhoon Abe (1990)」の詳細全文を読む スポンサード リンク
