Typhoon Emma trajectory analysis
Track and Movement Characteristics
Typhoon Emma (197407) 的生命史始 at Northwest Pacific低纬度海域, 整体路径呈现典型的“NW—转 toward NE”抛物线形态. formed初期 (6月12日至13日) , 系统位 at 8.1°N至11.7°N之间, 受引导气流影响稳定 toward NW, 经度从141.1°E迅速W移至136.1°E. 随后, Typhoon 维持WNW路径深入Philippines以E洋面, at 6月15日00:00到达最W端Position (15.9°N, 126.8°E) .
Notably, as the system approached 125°E, it did not continue westward to make landfall but instead made a clear turn. From 12:00 on June 15 to 00:00 on June 16, its moving direction gradually shifted from NW to NNE, marking the start of its transition. It then accelerated toward the NE, with its latitude rising rapidly from 20.1°N on June 17 to 32.5°N on June 19, while its longitude moved eastward to 138°E. It made no landfall throughout its lifetime, remained at sea, and ultimately weakened and dissipated over the mid- to high-latitude waters.
Intensity evolution and historical comparison
在Intensity变化方面, Typhoon Emma经历了完整的“ formed—增强—巅峰—减弱”过程. 初始阶段为Tropical Depression, max wind 维持在12m/s. 随着 toward WMoving, 系统逐渐整合加强, at 6月14日12:00升级为Tropical Storm (20m/s) , 并在次日00:00达到Severe Tropical Storm级别. 6月15日12:00, 系统在16.7°N, 125°E附近达到生命史巅峰, max wind 录得30m/s.
After the peak, influenced by environmental changes and toward NMovingGo to higher latitude waters, Typhoon Intensity rapidly declined. June 16 at 12:00 has fallen back to Tropical Storm level (23m/s) , and at June 17 at 12:00 further weakened into Tropical Depression.
Compared to typhoon, Emma's peak intensity is Severe Tropical Storm in 1974, compared to typhoon intensity in 1977 and 1965.
