Typhoon Wanda, international code 197102, international name WANDA, 1971 Northwest Pacific typhoon. Formed: 1971-04-23 06:00:00, ended: 1971-05-04 00:00:00. Peak intensity: Typhoon , minimum central pressure: 980 hPa, max wind: 38m/s.
Typhoon Wanda at 1971-04-23 06:00:00 at 12.4°N, 127.4°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Typhoon intensity with max winds of 38 m/s (~137 km/h) and a minimum central pressure of 980hPa, recorded at 1971-05-01 12:00:00.
Typhoon Wanda gradually weakened and was numbered off on 1971-05-04 00:00:00 was numbered off; its lifecycle recorded 44 track points.
Typhoon Wanda (197102) 的生命史始 at Northwest Pacific洋面, 整体路径呈现显著的“W行—N折”形态. formed初期 (4月23日至26日) , 系统位 at lat 10°至12°之间, 受引导气流影响, 稳定 toward W, During从127.4°E迅速W移至119.2°E, 横跨Philippines以E广阔海域. 4月27日至28日期间, 系统在S海中部海域 (约116°E-115°E) 出现短暂的移速减缓及纬 toward 徘徊, 中心The latitude维持在10.2°N至10.5°N附近, 显示此时环境流场较弱或存在多系统相互作用.
Since April 29, the path has seen a noticeable turn, the system begins toward NW direction to accelerate Moving, gradually approaching the Central S Peninsula E part coastal and Hainan Island to the E area. Until May 4, before disintegration, its center eventually reaches lat 20.2°N, 110.1° near. During its entire life cycle, the Typhoon has not landfall any land, has always been active at sea, avoiding the effects of direct disasters caused by Landfall, but its path covers the S Sea main navigation and surrounding sensitive waters.
Wanda的Intensity变化呈现出典型的“双峰型”或“波动增强”特征, 且伴随明显的减弱再加强过程. 初生阶段为Tropical Storm (23m/s) , 随后 at 4月25日增强为Severe Tropical Storm (30m/s) . 然而, Go to S海中部后, 受unknown环境因素影响, intensity 显著回落, 4月27日至28日降级为Nameless (最低wind speed12m/s-17m/s) . 值得注意的是, 系统在弱维持数日后, at 4月30日重新 intensified into Tropical Storm, 并在5月1日达到生命史巅峰, 升级为Typhoon intensity with max winds of 达38m/s. 此后Intensity迅速衰减, 5月3日降回Tropical Storm, 最终 at 5月4日以NamelessIntensity结束生命史.
Compared with the same name History, the 1971 Wanda peak intensity (Typhoon, 38m/s) high at 1977 Wanda (Tropical Storm) and 1974 Wanda (Severe Tropical Storm), but weak at 1962 Wanda (Severe Typhoon) . This suggests that in the 'Wanda' named sequence, the 1971 system is at a medium polar level, having a complete Typhoon-grade structure, but its Intensityins Time shorter, the peak passes rapidly weakening, showing signs of later environmental vertical wind shifts or greater ocean temperature support.
