Typhoon Nida, known in the Philippines as Typhoon Dindo, was the fourth tropical cyclone and second named storm of the 2004 Pacific typhoon season. Nida was the second super typhoon of the 2004 season, reaching a peak intensity of . Forming southeast of the Philippines, the storm strengthened as it moved northwest. The typhoon brushed the eastern Philippines causing heavy rains across the island archipelago. Nida later accelerated northeast, missing Japan to the east while becoming an extratropical cyclone. A total of $1.3 million (2004 USD) in damage occurred, and Nida left 31 fatalities. ==Meteorological history== On May 12, a persistent area of thunderstorms formed within a monsoon trough southwest of Palau. Satellite imagery revealed a weak low-level circulation. Initially, the Joint Typhoon Warning Center (JTWC) forecast the storm to not strengthen. The following day, forecasters saw that the storm was strengthening and upgraded the system to tropical depression status. Forecasters at the Philippine Atmospheric, Geophysical and Astronomical Services Administration designated the storm as Tropical Depression Dindo. At the time of formation, the depression was located east of Palau as it moved west northwest at 3 mph (5 km/h). Quickscat satellite imagery showed the depression's winds were near 29 mph (46 km/h) and increasing. Satellite imagery later the showed deep convection organizing over the low-level circulation. The depression underwent rapid intensification as it became a tropical storm late in the morning on May 14 and was assigned the name Nida by the Japan Meteorological Agency (JMA). Still intensifying, the storm turned northwest where it reached typhoon status later that night.〔 Curving west-northwest at 7 mph (11 km/h), Typhoon Nida attained winds of 115 mph (185 km/h), equivalent to a Category 3 hurricane. On May 16, Nida became a super typhoon as its winds reached 165 mph (266 km/h). At its peak, its highest winds extended 35 miles (56 km) from the center. Satellite imagery showed the storm developed a defined eye measuring 25 miles (40 km) wide. On May 17, the center of Nida passed over Catanduanes Island, Philippines.〔 After making landfall, Nida weakened and then turned more northward and slowed down. Re-entering the warmer waters of the Western Pacific Ocean, Nida's winds restrengthened to 150 mph (250 km/h). During the night of May 18, the typhoon began to weaken. Infrared satellite imagery showed the eye being obscured by high cirrostratus clouds, indicative of the weakening typhoon. The eyewall became significantly disorganized as Nida continued to recurve to the northeast.〔 Nida accelerated northeast and its maximum sustained winds weakened to 90 mph (148 km/h). Interacting with an upper level low pressure system over Japan, the typhoon became elongated. Nida weakened below typhoon strength as the center passed 290 miles (467 km) south of Tokyo, Japan. By May 21, Nida transitioned to an extratropical cyclone. The JMA continued to track the remnants of Nida as it weakened northeast of northern Japan.〔 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 Nida (2004)」の詳細全文を読む スポンサード リンク
