The SummaryTyphoon Betty (international code 196404) is a 1964 Northwest Pacific typhoon; peak intensity Super Typhoon, max wind 56m/s, minimum central pressure 960hPa, not in China Landfall, 1964-07-06 was numbered off, recording 20 track points.
Typhoon Betty, international code 196404, international name BETTY, 1964 Northwest Pacific typhoon. Formed: 1964-07-02 00:00:00, ended: 1964-07-06 18:00:00. Peak intensity: Super Typhoon, minimum central pressure: 960 hPa, max wind: 56m/s.
Typhoon Betty at 1964-07-02 00:00:00 at 21.8°N, 133.7°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 56 m/s (~202 km/h) and a minimum central pressure of 960hPa, recorded at 1964-07-05 06:00:00.
1964-07-06 18:00:00 After, Typhoon Betty gradually weakened and was numbered off on 1964-07-06 18:00:00 was numbered off; its lifecycle recorded 20 track points.
Typhoon Betty (196404) 的生命史始 at Northwest Pacific洋面, 整体呈现典型的NW toward Moving后转 toward NE的抛物线型路径. formed初期 (7月2日00:00) , 系统位 at 21.8°N, 133.7°E, 随后稳定 toward NW direction推进. 在7月2日至7月5日期间, Typhoon 中心The latitude从21.8°N持续N移至27.8°N, During从133.7°EW进至123.0°E, 显示出强劲的NW行进动力.
The crucial turning point of the path appeared on July 5 between 12:00 and 18:00. Previously Typhonined NW toward, but on July 5 after 18:00 (28.6°N, 122.8°E), the length changes slowed even slightly with E signs, until July 6 06:00 (30.5°N, 123.0°E) and subsequently, the path clearly turned to NE direction. This turning toward was usually caused by the wind slide pre-air flow guided. Thro the process, Typhon failed to landfall any land, all the way at sea activity, and finally at July 6 18:00 at 34.1°N, 125.3°Eaken weakened into Nameless and ended observations.
Betty的Intensity演变经历了快速增强, 巅峰维持及迅速减弱三个阶段. 从7月2日00:00的Nameless (15m/s) 起步, 系统在36h内迅速增强, at 7月3日06:00达到Super Typhoon级别 (51m/s) . 此后, Super Typhoon状态维持了长达66h, 直至7月5日06:00达到生涯峰值, max wind 录得56m/s. 值得注意的是, 在巅峰期附近, wind speed在51m/s至56m/s之间波动, 显示核心结构极为稳固.
However, once it starts toward NE, the intensity decreases significantly.From Super Typhoon (48m/s) to Nameless (15m/s) takes only about 48h, indicating that Go to High latitudes after cold sea or dry air invades, the energy supply is rapidly cut off.
Its peak intensity (56m/s, Super Typhoon) high at 1984 Betty (Severe Tropical Storm) and 1975 Betty (Severe Typhoon), at the same level as the Super Typhoon of the same name in 1987 and 1980.
