Typhoon Thelma, international code 199125, international name THELMA, 1991 Northwest Pacific typhoon. Formed: 1991-10-27 00:00:00, ended: 1991-11-08 12:00:00. Peak intensity: Tropical Storm, minimum central pressure: - hPa, max wind: 23m/s.
Typhoon Thelma at 1991-10-27 00:00:00 at 6°N, 148.8°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 -hPa, recorded at 1991-11-04 12:00:00.
1991-11-08 12:00:00 After, Typhoon Thelma gradually weakened and was numbered off on 1991-11-08 12:00:00 was numbered off; its lifecycle recorded 51 track points.
Typhoon Thelma (199125) 的生命史始 at 1991年10月27日00:00, formedPosition位 at Northwest Pacific低The latitude海域 (6°N, 148.8°E) , 初始状态为Nameless. 在整个生命周期内, 该系统始终维持在W行路径上, 未出现明显的N上转 toward 或Landfall行为. 从经纬度坐标序列分析, 其Moving direction主要受副热带高压S侧E气流引导, 整体呈现稳定的 toward WN至正W.
In terms of Moving speed, early October 27th to 30th) the system toward NW direction slowly advanced, the latitude rose from 6°N to 8.8°N, the length of W shifted about 8.6 degrees. Go to November, the path gradually turned to a more pure W-line Trend, especially during November 5th to 8th, the latitude fluctuated slightly between 10°N to 11.2°N, while the length moved from 124.7°E fast W to 106.8°E, indicating that the Late Moving speed was accelerated.
In terms of Intensity evolution, Thelma (199125) belonged to the weaker tropical cyclone. the system during the first nine days after formed (October 27th to November 4th) hasined the Nameless level, wind speed fluctuates between 7m/s to 17m/s, the enhancement process is extremely slow. until November 5th 00:00, the system only briefly intensified into Tropical Storm, reaching its peak intensity, max wind to 23m/s. However, this high Intensity state onlyined extremely short Time, the next day is weakened back to Nameless, and for the remaining life of the level to disperse, minimum pressure data loss, but based on speedwind judging its structure is more loose.
Historical data show that in 1987 Thelma had reached Super Typhoon level, in 1977 and 1980 the same name Typhoon also reached Severe Typhoon and Severe Tropical Storm intensity, and in 1983 Thelma was Severe Tropical Storm.
