Typhoon Nalgae trajectory
Track and Movement Characteristics
Typhoon Nalgae (2017 No. 11) had a relatively short lifespan, lasting about four and a half days from formation to dissipation. It formed over the open waters of the northwest Pacific (25.6°N, 165.7°E) and followed a stable northwestward, then north-northeastward track. From August 2 to 3, its center moved slowly north from 25.6°N to 27.5°N and west from 165.7°E to 164.2°E, displaying a typical northwestward track. Its movement was relatively slow, with brief periods of little or no movement, such as from 02:00 to 08:00 on August 3, when its coordinates remained 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, the length toward E retreated to 158.6°E, indicating that the system was significantly affected by the W-band guided airflow, completing the rapid shift from the tropical ocean toward toward to the high latitude region.
Intensity evolution and historical comparison
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, 显示出其在高纬度冷海水环境下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.
