The SummaryTyphoon Mirinae (international code 200921) is a 2009 Northwest Pacific typhoon; peak intensity Typhoon, max wind 40m/s, minimum central pressure 955hPa, not in China Landfall, 2009-11-02 was numbered off, recording 27 track points.
Typhoon Mirinae, international code 200921, international name Mirinae, 2009 Northwest Pacific typhoon. Formed: 2009-10-27 14:00:00, ended: 2009-11-02 20:00:00. Peak intensity: Typhoon , minimum central pressure: 955 hPa, max wind: 40m/s.
Typhoon Mirinae at 2009-10-27 14:00:00 at 14.9°N, 143.7°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Typhoon intensity with max winds of 40 m/s (~144 km/h) and a minimum central pressure of 955hPa, recorded at 2009-10-29 02:00:00.
2009-11-02 20:00:00 After, Typhoon Mirinae gradually weakened and was numbered off on 2009-11-02 20:00:00 was numbered off; its lifecycle recorded 27 track points.
Typhoon Mirinae (200921) formed at Northwest Pacific洋面, 整体路径呈现稳定的WN至正W走 toward , 全程无Landfall记录. 从经The latitude坐标序列分析, 该Typhoon 在生命史初期 (10月27日至28日) toward NW, 纬度从14.9°N小幅上升至16.3°N, During由143.7°E快速W移至134.0°E. 10月29日02:00达到最N端纬度16.3°N后, 路径出现明显转折, 随后转为持续 toward WMoving, 纬度逐渐S落. 在10月29日至11月2日期间, Typhoon 中心纬度由16.3°N逐步降至12.9°N, 经度则从134.0°E一路W进至108.6°E, 横跨约25个经度. 这种长距离的W行路径表明其主要受副热带高压S侧引导气流支配, Moving速度较快且 direction稳定, 未出现明显的回旋或停滞现象.
在Intensity变化方面, Typhoon Mirinae经历了“快速增强—维持巅峰—缓慢减弱”的过程. formed初期为Tropical Storm, 气压998hPa, wind speed18m/s. 在10月28日14:00至10月29日02:00的12h内, Pressure急剧下降33hPa至955hPa, max wind 增至40m/s, 迅速 intensified into Typhoon 级别. 此后近48h内 (10月29日02:00至10月30日11:00) , Typhoon 维持在peak intensity, 气压保持在955hPa, wind speed稳定在40m/s. 10月30日20:00起, 随着 toward W深入, intensity 开始减弱, 气压回升, wind speed下降, 最终 at 11月2日20:00消散前 weakened into Tropical Storm (20m/s, 995hPa) .
The intensity of Mirinae in 2009 is significantly stronger than the same name in History.Typhoon peak in 2021 is only Tropical Storm (minimum atmospheric pressure 990hPa), and the same name in 2016 is Severe Tropical Storm (minimum atmospheric pressure 980hPa) .And in 2009 Mirinae not only reached the typhoon level, its minimum atmospheric pressure (955hPa) and Max Wind (40m/s) are both far higher than the previous two times the same name typhoon, showing stronger energy release characteristics.
