Typhoon Jeff, international code 198816, international name JEFF, 1988 Northwest Pacific typhoon. Formed: 1988-09-12 06:00:00, ended: 1988-09-16 00:00:00. Peak intensity: Tropical Storm, minimum central pressure: 994 hPa, max wind: 23m/s.
Typhoon Jeff at 1988-09-12 06:00:00 at 15.8°N, 131.5°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Tropical Storm intensity with max winds of 23 m/s (~83 km/h) and a minimum central pressure of 994hPa, recorded at 1988-09-14 12:00:00.
Typhoon Jeff gradually weakened and was numbered off on 1988-09-16 00:00:00 was numbered off; its lifecycle recorded 16 track points.
Typhoon Jeff (198816)'s life history began at Northwest Pacific Ocean, the overall path showed a stable NE toward MovingTrend, with no significant turn toward or reversal. From the formed initial coordinate sequence, the system early (September 12, 06.00 to September 13, 06.00) mainlyined the latitude toward a weak W move or stagnation, the latitude slowly dropped from 15.8°N to 15.2°N, the length moved from 131.5°EE to 134.0°E, indicating that at this time the guiding air flow was weaker or somewhere at the saddle field. Since September 13, 06.00, the system began to establish a clearNEward toward Moving path, latitude continued N, steadily increased to 15.2°E. Until September 16,00, Center had reached 25.3°N
在Intensity变化方面, Jeff经历了一个短暂的增强后迅速减弱的过程. 系统初生时为Nameless, max wind 12m/s. 经过约两天的缓慢整合, at 9月14日06时 intensified into Tropical Storm, 并在同日12时达到peak intensity, max wind 录得23m/s. 值得注意的是, 该peak intensity仅维持了约18h, 随后自9月15日12时起, 系统重新 weakened into Nameless, wind speed回落至17m/s, 直至生命史结束. 气压数据缺失使得无法通过气压梯度进一步验证其结构紧密度, 但wind speed变化清晰反映了其“快生快灭”的特点.
In 1985, 6th Typhoon Jeff had reached Typhoon level, intensity far exceeding this year's Tropical Storm level; and in 1981, 22nd Typhoon Jeff was only Nameless, close to the final state of Jeff in 1988, but the system in 1988 at least reached the Tropical Storm standard.
