Typhoon Jean, international code 197113, international name JEAN, 1971 Northwest Pacific typhoon. Formed: 1971-07-09 12:00:00, ended: 1971-07-18 00:00:00. Peak intensity: Severe Typhoon, minimum central pressure: 975 hPa, max wind: 43m/s.
Typhoon Jean at 1971-07-09 12:00:00 at 10.5°N, 140.8°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Typhoon intensity with max winds of 43 m/s (~155 km/h) and a minimum central pressure of 975hPa, recorded at 1971-07-14 00:00:00.
1971-07-18 00:00:00 After, Typhoon Jean gradually weakened and was numbered off on 1971-07-18 00:00:00 was numbered off; its lifecycle recorded 35 track points.
Typhoon Jean (197113) 的生命史始 at 1971年7月9日12时的Northwest Pacific洋面, 初始Position位 at lat 10.5°N, 140.8°. 在 formed初期, 系统呈现 toward WN的Trend, 但在7月10日至11日期间出现短暂的Intensity波动与路径调整, 中心The latitude一度S落至9°N附近, 随后重新组织并稳定 toward WMoving. Go to 7月13日后, 随着系统深入S海E部海域, 其Moving路径逐渐转为稳定的NWW direction, 直逼中S半岛coastal . 整个生命周期内, 该Typhoon 未Landfall任何陆地, 最终 at 7月18日00时在Vietnam以E海域 (lat 19°N, 106.1°) weakened into Tropical Storm后结束观测. 从经纬度变化来看, 其路径整体呈抛物线状 toward W延伸, 横跨During超过34度, 显示出较强的长距离输送特征.
In terms of intensity evolution, Jean experienced a typical “enhancing-top-weakening” process. The system was rapidly enhanced after re-developing to Tropical Storm on July 12, and in less than two days Time was upgraded from Severe Tropical Storm to Severe Typhoon. On July 14, at 00, at 11.2°N, near 126.2°C reached the peak of life history, max wind recorded 43m/s, confirming that Severe Typhoon level. However, the peak stateined Time was shorter, then influenced by environmental factors, intensity began to shake down. It is worth noting that after Go to Sea SW (July 16, 17) , the system had a brief secondary reinforcement sign, wind speed rose back to 38m/s, but then rapidly weakened.
Compared with previously known Typhoon, in 1971 Jean's Intensity performance at a medium upper level. Compared with at 1974 Jean (top only for Tropical Storm) and 1965 Jean (top only for Super Typhoon), in 1971 the system did not reach the Super Typhoon level, but its 43m/s Max Wind was significantly higher at the 1974 case, and Severe Typhoonined a longer Time. Compared with the 1962 Jean (Severe Typhoon), both peak levels are the same, but in 1971 Jean's path is more S, without direct impact on the high latitude region.
