Typhoon Billie at 1964-09-25 12:00:00 at 13.5°N, 140°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 994hPa, recorded at 1964-09-30 06:00:00.
1964-10-01 12:00:00 After, Typhoon Billie gradually weakened and was numbered off on 1964-10-01 12:00:00 was numbered off; its lifecycle recorded 25 track points.
Typhoon Billie (196421) 的生命史始 at 1964年9月25日12时, formed at Northwest Pacific洋面 (13.5°N, 140°E) , 初始状态为Nameless. 在生命周期的前半段, 该系统呈现显著的W toward Moving特征. 从9月25日至9月27日中午, Typhoon 中心The latitude在13.5°N至14.5°N之间小幅波动, During由140°E快速W移至131.1°E, 表明其主要受E气流引导, Moving路径较为平直.
It is worth noting that between 12 a.m. and 28 a.m. on September 27th, the Typhoon center experienced a brief S-fracture, the latitude dropped from 13.7°N to 12.8°N, and then at 12 a.m. on September 28th again N raised to 13.5°N. After this tiny latitude shock, the system Go to the stable NW toward Moving phase. From noon on September 28th to noon on October 1st, the Typhoon continued toward NW direction advancing, penetrating the waters of the Vietnam Sea N, and finally at 12 a.m. on October 1st at 17.5°N and 105.2°E.
在Intensity变化方面, Typhoon Billie经历了一个缓慢增强后迅速减弱的过程. 初期维持NamelessIntensity (12-17m/s) 约三天. 9月28日12时, 随着wind speed增至20m/s, 系统升级为Tropical Storm. 此后Intensity稳步提升, at 9月29日12时达到Severe Tropical Storm级别 (28m/s) , 并在9月30日12时达到peak intensity, max wind 录得30m/s, 维持Severe Tropical Storm等级. 巅峰状态持续Time较短, 仅约12h后, 自10月1日00时起, wind speed开始下降至25m/s, 并 at 同日12时迅速 weakened into Nameless (15m/s) , 标志着其生命周期的结束.
Compared to the historically identical 'Billie' Typhoon, the 1964 Typehoon Intensity was significantly weaker.The data showed that the 1976s, 1973s and 1970s Typehoon peak intensity reached the Super Typhoon level, and in 1967 also reached the Typehoon level.In contrast, the 196421 Typehoon only reached the Severe Tropical Storm level, max wind 30m/s, not reached the Typehoon level standard (usually referred to as wind speed≥32.7m/s or wind force 12), belonging to a weaker example of Intensity in the same sequence.
