Typhoon Betty Route Analysis
Track and Movement Characteristics
Typhoon Betty (197511) formed at Northwest Pacific洋面, 整体路径呈现典型的W行转NW行Trend. 初始阶段 (9月16日至18日) , 系统位 at 140°E以E, 主要 toward NW, 纬度从10.2°N迅速提升至17.1°N, 经度则出现小幅W进后的短暂E退调整. 9月18日后, 路径转 toward 稳定W行, 穿越Philippines以E海域. 值得注意的是, 该Typhoon 在生命史中未发生Landfall, 始终在海上活动. Go to S海NE部后 (9月23日起) , 其Moving速度放缓并逐渐转 toward NNW direction, 最终 at 9月24日晚在25°N, 114.9°E附近减弱消散. 整个路径跨度较大, 从Tropical Depression发展为Typhoon , 再至 weakened into Tropical Depression, 完整经历了 formed, 发展, 成熟及消亡四个阶段.
Intensity evolution and historical comparison
Betty的Intensity演变具有明显的“快速增强-维持巅峰-迅速减弱”特征. 9月16日初生时气压为1007hPa, 随后持续加深. 9月21日14:00, 系统在22.6°N, 128°E附近达到Typhoon intensity with max winds of 增至40m/s, Pressure降至965hPa. 此后约36h内, 其Intensity维持在Typhoon 等级, minimum pressure 触及948hPa (9月22日02:00数据为950hPa, 结合巅峰数据推断极值出现在此期间) , max wind 保持40m/s. 然而, 自9月23日凌晨起, 随着系统靠近大陆边缘, intensity 急剧衰减, 气压回升至970hPa以上, wind speed骤降至35m/s及以下, 并 at 24日凌晨降级为Tropical Depression.
Compared with previous typhoons bearing the same name, Betty in 1975 reached a below-average to moderate intensity. Its peak central pressure of 948 hPa was far higher than the super typhoon records in 1972 (910 hPa), 1980 (925 hPa), and 1987 (891 hPa), but it was slightly stronger than the severe tropical storm in 1984 (980 hPa). This indicates that although Betty in 1975 reached typhoon strength, its explosiveness and extreme intensity were less pronounced than those of other Bettys in the same naming sequence, making it a tropical cyclone of typical intensity.

FAQ
Typhoon Betty was the 1975 Typhoon.
BETTY is the international name of Typhoon Betty. Its number 197511 is the historical number used by the CMA (the 11th typhoon of 1975). International numbering for Northwest Pacific typhoons did not begin until 1981. Before then, agencies such as the JMA (Japan) and the Joint Typhoon Warning Center in the USA used their own numbering systems, which may differ from the number assigned by China’s meteorological agencies and therefore cannot be compared directly.
Where does the track data for Typhoon Betty come from?
Track data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speeds are 2-minute sustained wind speeds.
What is the highest level of Typhoon Betty?
Typhoon Betty peak intensity is Typhoon , max wind 40m/s, minimum central pressure 948 hPa.
