Typhoon Thelma trajectory analysis
Track and Turning Characteristics
Typhoon Thelma (196211) formed at Northwest Pacific远洋海域, 初始Position位 at 17°N, 149°E. 在生命史初期, 该系统呈现稳定的NW toward MovingTrend. 从8月20日至8月24日, 其纬度由17°N迅速N抬至28.3°N, 经度则由149°EW进至137.3°E, 显示出较强的 toward W分量. 值得注意的是, 在8月24日02:00至20:00期间, 经度几乎停滞在137.3°E-137.4°E附近, 表明此时系统Moving速度减缓或处 at 路径转折的前兆阶段.
随后, 路径发生显著转 toward . 自8月25日起, Typhoon 主体开始加速 toward NE, 纬度在24h内从31.3°N跃升至35.8°N, 经度继续缓慢W移后转为E扩. 这种典型的“抛物线”路径特征, 符合中纬度W风带引导气流对Tropical Cyclone 的影响规律. 最终, 系统深入高纬度地区, at 8月29日消散 at 45.7°N, 160.2°E附近, 全程无Landfall记录, 主要活动范围集中在开阔洋面.
Intensity evolution and historical comparison
该Typhoon 经历了完整的生命周期演变, intensity 变化剧烈. formed初期为Tropical Depression, 随后快速增强, 仅用约3天Time便发展为Super Typhoon. 巅峰状态出现在8月25日14:00, 中心最低气压降至952hPa, max wind 达60m/s. 此后, 随着纬度升高及Go to 高纬冷海区, intensity 急剧衰减. 从8月25日的Super Typhoon到8月26日08:00的Severe Tropical Storm, 短短18h内wind speed骤降30m/s, 气压回升27hPa, 体现了温带变性过程中的能量快速耗散特征.
与同名History相比, 1962年Thelma的Intensity处 at 中等偏上水平. 相较 at 1991年, 1983年及1980年的同名Typhoon (巅峰仅为Tropical Storm或Severe Tropical Storm, minimum pressure 在978hPa-990hPa之间) , 1962年版本Intensity显著更强. 然而, 与1987年Thelma (最低气压911hPa的Super Typhoon) 相比, 其peak intensity仍有一定差About . 总体而言, 1962年Thelma是一个在远洋完成高Intensity发展并典型转 toward 的高纬度Typhoon 案例.

FAQ
Thelma was the 1962 Typhoon.
The designation 196211 for Typhoon Thelma is the historical number retained by the CMA, meaning the 11th typhoon of 1962, while its international name was THELMA. The internationally unified numbering system for the Northwest Pacific began only in 1981. Before then, different agencies assigned their own numbers, so the JMA in Japan, the Joint Typhoon Warning Center in the United States, and Chinese meteorological authorities may have used different numbers for the same typhoon; these cannot be directly compared.
Where does the track data for Typhoon Thelma come from?
Track data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speeds are 2-minute sustained wind speeds.
What is the most powerful Typhoon Thelma?
Typhoon Thelma peak intensity is Super Typhoon, max wind 60m/s, minimum central pressure 948 hPa.
Is the Typhoon Thelma Landfall?
According to records, the Typhoon Thelma is not in our coastal Landfall.
