1971-10-23 18:00:00 After, Typhoon Hester gradually weakened and was numbered off on 1971-10-23 18:00:00 was numbered off; its lifecycle recorded 18 track points.
Typhoon Hester (197129) 的生命史始 at Northwest Pacific洋面, 整体呈现稳定的WNMovingTrend. formed初期 (10月19日12时至20日06时) , 系统中心The latitude维持在9.5°N至9.6°N之间, During从129.8°E快速W移至125.4°E, 表现为近乎正W direction的平移运动. 随后, 路径逐渐 toward N分量增加, 转 toward NW direction行进. 从10月21日00时至23日18时, Typhoon 中心纬度由9.7°N持续N抬至16.4°N, 经度由121.2°EW进至106.2°E. 整个过程中未出现明显的路径折 toward 或停滞, Moving轨迹平滑连贯. 值得注意的是, 该Typhoon 全程在海上活动, 无Landfall记录, 最终在Vietnam以E近海海域减弱消散.
Hester's Intensity change underwent three stages of 'enhancing -ining peak - rapidly weakening'.The initial phase was Nameless, then rapidly intensified into Severe Tropical Storm. At noon on October 20th there was a short fluctuation, wind speed dropped to 23m/s, but then recovered and continued to improve. On October 21st at 06:00 upgrade to Typhoon level (35m/s) , and steadily strengthened within the following 36h. On October 22st at 12th reached Severe Typhoon intensity with max winds of increased to 43m/s, and at October 22st at 18:00 to 23:00 reached a peak, max windined at 46m/s. Peak Time lasted about 12h.
Compared with Hester in 1968 (top only to Severe Tropical Storm) and Hester in 1963 (top only to Tropical Storm), the system in 1971 was more fully developed, reaching Severe Typhoon level.
