Typhoon Atsani trajectory analysis
Track and Turning Characteristics
Typhoon Atsani (201516) 的生命史长达15天, 整体路径呈现显著的NW toward Moving后转为NE toward 的抛物线形态. formed初期 (8月14日至16日) , 系统位 at lat 14.5°至15.7°N, 159.9°至163.5°之间, 主要维持WNW. 随着纬度逐渐升高, 路径在8月20日前后出现明显转折. 从坐标序列分析, 8月20日14:00位 at (22°N, 148.5°E), 随后至8月21日20:00移至(25.6°N, 145.4°E), 此时经度开始 toward E回调, 标志着Typhoon 完成从NW行到N上的过渡. Go to 中高纬度后, 受W风带引导气流影响, 路径迅速转 toward NE. 8月23日至29日期间, 纬度从29°N急剧攀升至45°N, 经度从145.2°E大幅E移超过22个经度至167.7°E, 显示出典型的温带气旋转化过程中的加速E移特征. 全生命周期内无Landfall记录, 始终在开阔洋面上活动.
Intensity evolution and historical comparison
Atsani经历了完整的“增强-巅峰-减弱”过程, 且peak intensity极高. 初始阶段为Tropical Depression (13m/s) , 随后快速加强, 仅用约4天Time便发展为Super Typhoon. 8月18日至20日为Intensity巅峰期, Pressure低至920hPa (观测数据中最低记录为920hPa, track points中显示最低为930hPa, 此处以题目给出的巅峰数据为准) , max wind 达62m/s. 值得注意的是, 在8月20日14:00, 其Intensity仍维持在58m/s, 930hPa的Super Typhoon级别. 此后, 随着纬度N抬和海温降低, intensity 开始衰减. 8月21日后降为Severe Typhoon, 8月23日进一步 weakened into Typhoon . Go to 40°N以N的高纬海域后, 系统迅速转化为温带气旋性质, wind speed降至13m/s, 气压回升至1000hPa以上.
Compared with typhoons bearing the same name in later years, the 2015 Atsani was far more intense. The 2020 Atsani peaked only as a severe tropical storm, with a central pressure of 985hPa, while the 2026 Atsani reached only tropical storm status, with a central pressure of 998hPa. As a super typhoon, the 2015 Atsani had a minimum central pressure 65hPa lower than the 2020 storm of the same name, demonstrating its exceptionally powerful burst of energy and making it the strongest of the three.
