The SummaryTyphoon Jangmi (international code 200815) is a 2008 Northwest Pacific typhoon; peak intensity Super Typhoon, max wind 65m/s, minimum central pressure 910hPa, not in China Landfall, 2008-10-01 was numbered off, recording 95 track points.
Typhoon Jangmi, international code 200815, international name JANGMI, 2008 Northwest Pacific typhoon. Formed: 2008-09-24 20:00:00, ended: 2008-10-01 02:00:00. Peak intensity: Super Typhoon, minimum central pressure: 910 hPa, max wind: 65m/s.
Typhoon Jangmi at 2008-09-24 20:00:00 at 12.1°N, 136.4°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Super Typhoon intensity with max winds of 65 m/s (~234 km/h) and a minimum central pressure of 910hPa, recorded at 2008-09-27 14:00:00.
2008-10-01 02:00:00 After, Typhoon Jangmi gradually weakened and was numbered off on 2008-10-01 02:00:00 was numbered off; its lifecycle recorded 95 track points.
Typhoon Jangmi (200815) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW行—N折—NE转 toward ”的抛物线形态. formed初期 (9月24日) , 系统位 at 136.4°E附近, 稳定 toward NW. 随着The latitude升高至20°N以N, 受副热带高压边缘气流及W风带槽前SW气流的total 同引导, 其Moving路径逐渐 toward N偏移. 在9月27日至28日期间, Typhoon 中心逼近Taiwan以E洋面 (约121°E-124°E区间) , 此时为路径的最W端点, 随后路径发生显著转折, 由NW toward 转为正N, 进而 toward NE direction加速Moving. 整个过程中, Typhoon 未Landfall任何陆地, 始终在海上活动, 最终 at 10月1日凌晨在29.8°N, 128.5°E附近减弱消散. 从坐标序列看, 其在高纬度地区 (25°N以N) During toward E回撤明显, 体现了中纬度W风带对typhoon track的显著牵引作用.
Jangmi's Intensity evolution experienced rapid enhancement, peak maintenance and rapid weakening in three stages. Starting from the September 24th Tropical Storm (18m/s, 996hPa), the systemined an explosive enhancement in just three days, to reach its peak on September 27th 14th, the center's lowest air pressure dropped to 910hPa, the max wind reached 65m/s, established as the Super Typhoon level. It is worth noting that itined about 9h at 910hPa's low atmospheric pressure (until 27th 23h) , showing extremely strong core structural stability. However, since September 28th, as the latitude further increased and possible vertical wind cuts grew, the intensity began to drop sharply, the 24hwind speed gradually dropped
Its peak air pressure (910hPa) is far lower at 2026 Yangmi (970hPa), 2014 Yangmi (988hPa) and 2020 Yangmi (992hPa) .The latter peak intensity is only typhoon or tropical storm level, respectively, and 2008 Yangmi is rare Super Typhoon, indicating that the atmospheric environment of the year is more favorable at the deep coalescence development and energy accumulation of the tropical cyclone.
