The SummaryTyphoon Nalgae (international code 201711) is a 2017 Northwest Pacific typhoon; peak intensity Tropical Storm, max wind 23m/s, minimum central pressure 990hPa, not in China Landfall, 2017-08-06 was numbered off, recorded 26 track points.
Typhoon Nalgae, international code 201711, international name NALGAE, 2017 Northwest Pacific typhoon. Formed: 2017-08-02 08:00:00, ended: 2017-08-06 14:00:00. Peak intensity: Tropical Storm, minimum central pressure: 990 hPa, max wind: 23m/s.
Typhoon Nalgae at 2017-08-02 08:00:00 at 25.6°N, 165.7°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Tropical Storm intensity with max winds of 23 m/s (~83 km/h) and a minimum central pressure of 990hPa, recorded at 2017-08-04 14:00:00.
Typhoon Nalgae gradually weakened and was numbered off on 2017-08-06 14:00:00 was numbered off; its lifecycle recorded 26 track points.
Its initial Position at Northwest Pacific Oceans (25.6°N, 165.7°E) , the overall path shows a stable NW toward turn NE toward MovingTrend. During August 2 to August 3, Typhoon's center latitude moved from 25.6°N slowly to 27.5°N, length from 165.7°EW back to 164.2°E, displayed as typical NW, but Moving speed was relatively slow, during the period there was a brief stagnation of the phenomenon (such as August 3 02:00 to 08:00 UTC unchanged).
After August 4th, as the latitude broke 28°N, the Typhoon Moving direction gradually shifted toward N, then significantly shifted toward NE direction accelerated Moving during August 5th to August 6th. Especially during August 5th to August 6th, between 17:00 and 14:00, the latitude rapidly jumped from 35.4°N to 41.8°N, and the length toward E rebounded to 158.6°E, indicating that the system was significantly affected by the W wind belt guided airflow, completing the rapid shift from the tropical ocean toward high latitude region.
在Intensity方面, “Nalgae”维持Tropical Storm等级 throughout 其生命史, 未发展为Severe Tropical Storm或Typhoon 级别. 其中心最低气压从初始的998hPa逐步下降, at 8月4日17:00达到peak intensity, 此时Max Wind为23m/s, minimum pressure 降至990hPa. 此后直至消散, 其Intensity基本维持在巅峰状态附近, 仅在最后阶段wind speed微降至20m/s, 气压保持990hPa不变, 显示出其在高The latitude冷海水环境下Intensity衰减较慢的特征.
与历届同名Typhoon 相比, 2017年“Nalgae”的Intensity明显偏弱. 2011年第19号Typhoon “Nalgae”曾达到Severe Typhoon级别, minimum pressure 低至945hPa; 2022年第22号Typhoon “Nalgae”也达到了Typhoon 级别, minimum pressure 为975hPa. 相比之下, 2017年“Nalgae”与2005年第6号Typhoon “Nalgae”Intensity相当, 后者巅峰同样为Tropical Storm, minimum pressure 同为990hPa. 这表明“Nalgae”这一命名在不同年份对应的系统Intensity差异巨大, 2017年的系统属 at 其中较弱的一类, 主要受限 at formedPositionN及环境条件限制, 未能获得充足的能量支持以进一步发展.
