Typhoon Jeff, international code 198506, international name JEFF, 1985 Northwest Pacific typhoon. Formed: 1985-07-21 00:00:00, ended: 1985-08-02 00:00:00. Peak intensity: Typhoon , minimum central pressure: 970 hPa, max wind: 38m/s.
Typhoon Jeff at 1985-07-21 00:00:00 at 19.4°N, 146°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 38 m/s (~137 km/h) and a minimum central pressure of 970hPa, recorded at 1985-07-30 06:00:00.
Typhoon Jeff gradually weakened and was numbered off on 1985-08-02 00:00:00 was numbered off; its lifecycle recorded 49 track points.
Typhoon Jeff (198506) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现显著的“先N后W再NE”的复杂折线形态. formed初期 (7月21日至24日) , 系统主要 toward N, The latitude从19.4°N迅速攀升至26.6°N, During在146°E附近小幅摆动, 显示出受副热带高压W侧边缘引导气流影响的特征. 7月25日至27日期间, 路径出现明显W折, 中心经度从144.9°E快速W移至134.2°E, 同时纬度略有S落, 表明其受到W风带或周边环流系统的牵引作用发生转 toward . 7月28日后, Typhoon 再次调整 direction, 稳定 toward WN, 直至7月31日到达29.3°N, 120.6°E附近. 随后, 系统Go to 加速N上阶段, 最终 at 8月2日消散 at 37.5°N的高纬度海域. 全生命周期内无Landfall记录, 主要在海上活动.
In terms of Intensity changes, Jeff experienced two obvious enhancements.The first enhancement took place on July 21-23, from Nameless rapidly evolving into Severe Tropical Storm, max wind reaching 28m/s. Then on July 25-26 experienced a brief weakening, the lowest falling to Nameless level (15m/s).The second enhancement was more notable, since July 27 re-evolving into Tropical Storm, and at July 29 intensified into Typhoon, the peak state appeared on July 30th, max wind reaching 35m/s, close to the highest Intensity38m/s in its entire history.
In 1988, Jeff (198816) peak intensity was only Tropical Storm, and in 1981, Jeff (198122) onlyined Nameless Intensity.This suggests that Jeff in 1985 was ranked in the same sequence of names at the stronger energy, more complete typhoon individual, whose Max Wind far surpassed the other two, reflecting the stronger dynamic conditions of Northwest Pacific Typhoon activity that year.
