Typhoon Thelma, international code 198704, international name THELMA, 1987 Northwest Pacific typhoon. Formed: 1987-07-06 12:00:00, ended: 1987-07-16 12:00:00. Peak intensity: Super Typhoon, minimum central pressure: 915 hPa, max wind: 66m/s.
Typhoon Thelma at 1987-07-06 12:00:00 at 9.6°N, 150.9°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 66 m/s (~238 km/h) and a minimum central pressure of 915hPa, recorded at 1987-07-11 12:00:00.
1987-07-16 12:00:00 After, Typhoon Thelma gradually weakened and was numbered off on 1987-07-16 12:00:00 was numbered off; its lifecycle recorded 41 track points.
Typhoon Thelma (198704) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW行-N转-NE移”抛物线型轨迹. formed初期 (7月6日至8日) , 系统在低The latitude海域稳定 toward NW, 经纬度从(9.6°N, 150.9°E)移至(15°N, 143.8°E), 期间完成从Nameless到Tropical Storm的Intensity升级. 7月9日至12日, 系统维持WNW路径, 快速穿越Philippines以E洋面, Center由(16.5°N, 139.7°E)推进至(18.5°N, 126.6°E). 值得注意的是, 该Typhoon 在接近126°E经线附近时出现路径转折迹象, 随后逐渐转为 toward NMoving. 7月13日后, 受中高纬度W风带引导气流影响, 路径显著转 toward NE, 经过E海E部海域后加速 toward Japan以S及以E海域移去, 最终 at 7月16日在高纬度地区减弱消散. 全生命周期内无Landfall记录, 主要活动范围集中在开阔洋面.
From the Tropical Storm (20m/s) on July 8 to the Super Typhoon (64m/s) on July 11, for only about 3 days, the max wind increased to 44m/s, peak intensity reached 66m/s, establishing its Super Typhoon level. July 11-12 was the intensity peak period, then began to slowly weaken.
In 1991, the Thelmapeak intensity in 1983 and 1980 was only at the level of Tropical Storm or Severe Tropical Storm, in 1977 Thelmah although reached the Severe Typhoon level, but still did not reach the Super Typhoon threshold.
