Typhoon Helen trajectory analysis
Track and Movement Characteristics
Typhoon Helen (196410) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW—NE”抛物线型Moving特征. formed初期 (7月27日至29日) , 系统自150°E附近 toward NW direction稳定推进, 纬度从16.9°N迅速N抬至22.6°N, 经度W移约4.6度, 显示出良好的引导气流支持. 7月30日至8月1日期间, Typhoon 维持高Intensity并 toward WNW direction深入, 到达最W端Position约为131.1°E, 29.8°N附近, 此处可视为路径的转折点. 随后, 受中高纬度W风带影响, 路径发生显著转 toward , 开始加速 toward NE. 8月2日后, Moving速度明显加快, 纬度在48h内从32.4°N跃升至43.8°N, 最终 at 8月6日在46.7°N, 145°E附近减弱消散. 全生命周期内无Landfall记录, 主要活动区域为开阔洋面.
Intensity evolution and historical comparison
Helen’s intensity evolved through three stages: rapid intensification, a prolonged peak, and gradual weakening. During the initial stage, its central pressure fell rapidly from 1006 hPa to 990 hPa in about 36 hours. At 08:00 on July 30, the pressure dropped to 940 hPa and the wind speed reached 65 m/s, establishing its status as a super typhoon. It reached its peak at 02:00 on July 31, with a lifetime minimum central pressure of 935 hPa and maximum winds of 75 m/s. This peak intensity lasted for a considerable time, and Helen remained at severe typhoon intensity through August 1. After entering higher-latitude waters, it weakened steadily in response to cold sea temperatures and vertical wind shear, and was downgraded to a tropical depression on August 4.
Compared with other storms of the same name in the historical record, Helen in 1964 was significantly stronger. Its peak central pressure of 935 hPa was far lower than those of Helen in 1972 at 958 hPa and Helen in 1995 at 980 hPa, as well as the tropical-storm-intensity typhoons of 1992 and 1975. As the tenth typhoon of the 1964 season, its maximum winds of 75 m/s and exceptionally low central pressure of 935 hPa made it the most destructive and intense among the listed storms named Helen, reflecting the vigorous typhoon activity in the Northwest Pacific that year.

FAQ
Typhoon Helen was the 1964 Typhoon.
The number 196410 used for Typhoon Helen is the historical identifier retained by the CMA, meaning the tenth typhoon of 1964. Its international name was HELEN. The unified international numbering system for the Northwest Pacific did not begin until 1981. Before then, individual agencies used separate numbering systems, so the numbers assigned by JMA (Japan), the Joint Typhoon Warning Center of the United States, and China’s meteorological authorities may differ for the same storm and are not directly comparable.
Where does Typhoon Helen's track data 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 highest level of Typhoon Helen?
Typhoon Helen peak intensity is Super Typhoon, max wind 75m/s, minimum central pressure 935 hPa.
Typhoon Helen Landfall?
According to records, Typhoon Helen is not in our coastal landfall.
Where can I view typhoon Helen's live track map?
