Typhoon Sinlaku was a damaging typhoon that affected Okinawa, Taiwan, and eastern China in September 2002. The 16th named storm of the 2002 Pacific typhoon season, Sinlaku formed on August 27 northeast of the Northern Marianas Islands. After initially moving to the north, it began a generally westward motion that it maintained for the rest of its duration. Sinlaku strengthened into a typhoon and attained its peak winds on August 31. Over the next few days, it fluctuated slightly in intensity while moving over or near the Ryukyu Islands. On September 4, the typhoon's eye crossed over Okinawa. It dropped heavy rainfall and produced strong winds that left over 100,000 people without power. Damage on the island was estimated at $14.3 million. After affecting Okinawa, Sinlaku threatened northern Taiwan, which was previously affected by two deadly typhoons in the previous year. Officials enacted many preparations, although damage ended up being minimal on the island. Two people were killed on Taiwan, however. Sinlaku weakened slightly before making its final landfall in eastern China near Wenzhou on September 7. There, the storm produced a record wind gust of 204 km/h (127 mph), and just south of the city, high waves destroyed several piers and a large boat. High rainfall and winds from Sinlaku destroyed 58,000 houses, and large areas of crops were destroyed. Damage in China was estimated at $709 million, and there were 28 deaths there. ==Meteorological history== The Joint Typhoon Warning Center (JTWC) began monitoring a tropical disturbance on August 26, noting that an area of convection had an associated circulation. With favorable conditions, the agency assessed a fair potential for development. On August 27, the Japan Meteorological Agency (JMA) classified the system as tropical depression south of the Japanese island of Minamitorishima,〔 although the circulation was exposed from the convection. The next day, the JTWC initiated warnings on Tropical Depression 22W about 945 km (565 mi) northeast of Saipan, after the thunderstorms began wrapping into the center.〔 Initially, the depression moved generally northward through a weakness in the subtropical ridge,〔 strengthening into Tropical Storm Sinlaku on August 29.〔 The building ridge, located east of Japan, gradually turned the storm westward.〔 As early as August 29, the JTWC reported that an eye feature was beginning to develop.〔 After further intensification, Sinlaku strengthened, and the JMA upgraded it to a typhoon on August 31; the JTWC estimated Sinlaku attained typhoon status a day earlier. Shortly after Sinlaku become a typhoon, the JMA estimated it attained peak 10 minute maximum sustained winds of 150 km/h (90 mph).〔 Also on August 31, the JTWC estimated peak 1 minute winds of 205 km/h (125 mph).〔 On September 1, Sinlaku began undergoing an eyewall replacement cycle, although cooler water temperatures caused by previous Typhoon Rusa prevented restrengthening.〔 The typhoon turned more to the west-northwest on September 2, and without much change in intensity, it passed just south of Iwo Jima that day and very near the Japanese island of Minamidaitojima around 2130 UTC on September 3. The next day, Sinlaku also passed just south of Okinawa,〔 although its large 110 km (70 mi) eye crossed over the southern portion of the island; the JTWC estimated the storm had winds of 175 km/h (110 mph) while passing near Okinawa.〔 A trough passing north of Sinlaku slowed the typhoon's westward movement. Dry air in the region,〔 and later increased wind shear caused a steady weakening trend. On September 6, Sinlaku passed a short distance north of Taiwan,〔 and subsequently a west-northwest motion resumed.〔 The JMA downgraded the typhoon to a severe tropical storm on September 7 in the East China Sea,〔 although the JTWC maintained it as a typhoon.〔 Around 1030 UTC that day, Sinlaku made landfall in east-central China near Wenzhou, a city near the border of Zhejiang and Fujian provinces.〔 The storm weakened while progressing inland, although its circulation remained well-defined until dissipating on September 9.〔〔〔 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 Sinlaku (2002)」の詳細全文を読む スポンサード リンク
