Typhoon Judy, international code 197816, international name JUDY, 1978 Northwest Pacific typhoon. Formed: 1978-09-09 06:00:00, ended: 1978-09-17 06:00:00. Peak intensity: Severe Typhoon, minimum central pressure: 950 hPa, max wind: 46m/s.
Typhoon Judy at 1978-09-09 06:00:00 at 19.5°N, 164.7°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Typhoon intensity with max winds of 46 m/s (~166 km/h) and a minimum central pressure of 950hPa, recorded at 1978-09-15 18:00:00.
1978-09-17 06:00:00 After, Typhoon Judy gradually weakened and was numbered off on 1978-09-17 06:00:00 was numbered off; its lifecycle recorded 33 track points.
Typhoon Judy (197816) 的生命周期始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW-NE”抛物线型Moving特征. formed初期 (9月9日至12日) , 系统位 at lat 19.5°至24°N, 164.7°至147.2°之间, 主要受副热带高压S侧引导气流影响, 保持稳定的NW toward Moving. 在此期间, The latitude逐渐N抬, During持续W进, Moving速度相对均匀.
关键的转 toward 过程发生在9月13日至14日期间. 当系统Moving至lat 25.5°N, 146.4°附近时, Moving direction开始由NW转为正N, 随后进一步 toward E偏转. 9月15日06:00至18:00, Typhoon 中心 at 30.5°至32.5°之间短暂停滞并略微E移, 标志着其完全Go to W风带控制区域. 此后, 路径迅速转 toward NE, at 9月17日消散前到达lat 42°N, 156.6°的高The latitude海域. 整个生命周期内, 该Typhoon 未Landfall任何陆地, 始终在洋面上活动.
从Intensity演变来看, Judy经历了完整的“ formed-加强-巅峰-减弱”过程. 初生阶段为Nameless, wind speed维持在10-17m/s. 9月13日06:00增强为Tropical Storm, 随后快速加强, at 9月14日18:00达到Typhoon 级别 (35m/s) . peak intensity出现在9月15日18:00至9月16日06:00, 中心Max Wind达到46m/s, 评定为Severe Typhoon等级. 值得注意的是, 在达到巅峰后, Typhoon 并未立即减弱, 而是维持了约12h的Severe TyphoonIntensity, 随后在高The latitude冷空气及海洋热力条件变化的影响下迅速衰减, 9月17日06:00已 weakened into Tropical Storm.
与同名History对比, 1978年Judy的peak intensity (Severe Typhoon, 46m/s) 略低 at 1979年Judy (Super Typhoon) , 但与1989年, 1986年及1982年的同名Typhoon (均为Severe Typhoon) 处 at 同一Intensity量级. 这表明在该命名序列中, Severe Typhoon是较为常见的巅峰形态, 而1978年Judy的路径更偏 toward 高The latitude转 toward , 避免了近海Landfall带来的直接灾害影响.
