Typhoon Betty at 1969-08-05 06:00:00 at 14°N, 138.1°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Typhoon intensity with max winds of 35 m/s (~126 km/h) and a minimum central pressure of 960hPa, recorded at 1969-08-08 00:00:00.
1969-08-09 12:00:00 After, Typhoon Betty gradually weakened and was numbered off on 1969-08-09 12:00:00 was numbered off; its lifecycle recorded 18 track points.
Typhoon Betty (196906) 的生命周期始 at 1969年8月5日06时, formed at Northwest Pacific洋面 (14°N, 138.1°E) . 在初始阶段, 该系统保持稳定的NW toward MovingTrend. 从8月5日至8月7日中午, 其中心坐标由138.1°E持续W移至125.1°E, The latitude由14°NN抬至23.5°N, 显示出典型的副热带高压S侧引导气流特征. 值得注意的是, 在8月8日06时至18时期间, Typhoon During从121.6°E急剧变化至115°E, 而纬度仅从25.7°N微增至26.5°N, 这表明系统在接近大陆边缘时出现了显著的W折加速现象, Moving direction由NW转为近乎正W. 随后, 系统继续 toward N深入内陆, 最终 at 8月9日12时在28°N, 114°E附近 weakened into Nameless并结束观测. 整个路径呈现平滑的抛物线形态, 无Landfall记录, 主要活动区域集中在开阔海域及coastal 地带.
Betty's Intensity development underwent the process of 'slow enhancement - fast peak - rapid decline'. initially as Tropical Storm, wind speedined at 20-23m/s for about 30h. On August 6th at 18, the system intensified into Severe Tropical Storm, and at August 7th at 12 officially upgraded to Typhoon, max wind reached 33m/s. Peak state appeared on August 8th at 00 to 06h, max wind recorded 35m/s. Then, as the system W folded and approached the land, intensity began to decline rapidly, August 8th at 12wind speed dropped to 33m/s, and at 18th further weakened into Severe Tropical Storm (30m/s). Go to August 9th, the deceleration rate accelerated, within a short 12h by
Data show that 1980 Betty (198021) and 1987 Betty (198708) both reached 'Super Typhoon' level, 1975 Betty (197511) also reached 'Severe Typhoon' level, and 1969 Betty only 'Typhoon' level, max wind 35m/s much lower at the previous year's peak intensity.
