Typhoon Helen, international code 196410, international name HELEN, 1964 Northwest Pacific typhoon. Formed: 1964-07-27 18:00:00, ended: 1964-08-03 12:00:00. Peak intensity: Super Typhoon, minimum central pressure: 930 hPa, max wind: 66m/s.
Typhoon Helen at 1964-07-27 18:00:00 at 19.5°N, 149.5°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 66 m/s (~238 km/h) and a minimum central pressure of 930hPa, recorded at 1964-07-30 00:00:00.
1964-08-03 12:00:00 After, Typhoon Helen gradually weakened and was numbered off on 1964-08-03 12:00:00 was numbered off; its lifecycle recorded 28 track points.
Typhoon Helen (196410) 的生命周期始 at 1964年7月27日18时, formed at Northwest Pacific洋面 (19.5°N, 149.5°E) , 终 at 1964年8月3日12时在较高The latitude海域 (39.2°N, 122.3°E) 减弱消散. 从整体路径来看, 该Typhoon 呈现典型的NW toward MovingTrend, 随后逐渐转 toward NE direction. 在 formed初期至7月30日期间, Typhoon 中心稳定 toward NW direction推进, 纬度从19.5°N迅速上升至25.3°N, During由149.5°EW移至139.5°E, 显示出较强的 toward W分量.
From July 31 to August 1, Typhoon Moving direction gradually shifted from NW to N, and then toward NE. Especially after August 1 at 06:00 (29.8°N, 131°E), the length toward E retreat trend established, marking its Go to turn toward phase.
Helen's Intensity evolution experienced rapid enhancement, peak maintenance and slow decline in three phases. Starting from the 27th of July's Nameless (17m/s), it rapidly intensified into Super Typhoon in about 48h. July 29th at 18h wind speed has reached 61m/s, reached peak intensity at 06:00 on July 30th, max wind recorded 66m/s, and subsequentlyined Super Typhoon level above 61m/s in about 36h (until July 31st at 18h), showing strong structural stability.
8月1日06时起, 随着The latitude突破30°N, 受环境场影响, Typhoon 开始显著减弱, wind speed从51m/s逐步降至8月3日12时的20m/s. 在与同名Typhoon 的横 toward 对比中, 1964年Helen的peak intensity (66m/s, Super Typhoon)显著高 at 1995年, 1992年及1975年的同名Typhoon (后者多为Tropical Storm或普通Typhoon ). 仅与1972年Helen (197214) 相比, 两者均达到Super Typhoon级别, 表明“Helen”这一命名在特定年份易孕育出高Intensity热带气旋, 但1964年Helen凭借长达数日的Super Typhoon维持期, 展现了更为持久的破坏潜力.
