Typhoon Helen, international code 196618, international name HELEN, 1966 Northwest Pacific typhoon. Formed: 1966-09-19 00:00:00, ended: 1966-09-24 18:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 978 hPa, max wind: 30m/s.
Typhoon Helen at 1966-09-19 00:00:00 at 19.4°N, 131.3°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Tropical Storm intensity with max winds of 30 m/s (~108 km/h) and a minimum central pressure of 978hPa, recorded at 1966-09-23 06:00:00.
1966-09-24 18:00:00 After, Typhoon Helen gradually weakened and was numbered off on 1966-09-24 18:00:00 was numbered off; its lifecycle recorded 24 track points.
Typhoon Helen (196618) 的生命周期始 at 1966年9月19日00时, 终 at 9月24日18时, 全程未Landfall陆地. 从空间轨迹来看, 该Typhoon 整体呈现显著的NW至NE转 toward 路径. formed初期 (9月19日至20日) , 系统位 at lat 19.3°-19.5°N, 127.7°-131.3°之间, 主要维持 toward WN direction缓慢Moving, The latitude变化极小, During toward W推进约3.6个经度.
As on the system N, the Moving direction gradually transitioned from W toward N, and accelerated toward NE between September 22 and 23, especially between September 23:00 and 24:00, the latitude rapidly jumped from 25.3°N to 29.6°N, the length also toward E retreated to 129.3°E, showing the typical turn toward characteristics occurring under the influence of the W wind belt guided air flow.
在Intensity变化方面, Helen经历了“ formed-增强-巅峰-减弱”的完整过程. 初始阶段为Nameless, max wind 12m/s. 9月21日00时 intensified into Tropical Storm (20m/s) , 随后快速增强, at 9月21日12时达到Severe Tropical Storm级别 (25m/s) . 此后近两天Time内, intensity 维持在Severe Tropical Storm等级, wind speed在25m/s至28m/s之间波动. 9月23日12时, 系统在27°N附近达到生命周期内的peak intensity, max wind 录得30m/s.
After the peak, as the latitude continued to rise to 30°N by N, the environmental conditions were no longer favorable atining high Intensity, the system rapidly weakened.
Compared to the previous typhoon, the peak intensity (Severe Tropical Storm, 30m/s) of Helen in 1966 was at a medium weak level. compared to the 1972 super typhoon and the 1995 typhoon, its intensity was significantly weaker; but the peak intensity of Helen in 1966 was slightly higher than that of Helen in 1975 and Helen in 1992 (both tropical storms), showing a certain annual difference.
