Typhoon Winona, international code 198517, international name WINONA, 1985 Northwest Pacific typhoon. Formed: 1985-09-19 00:00:00, ended: 1985-09-22 06:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 990 hPa, max wind: 25m/s.
Typhoon Winona at 1985-09-19 00:00:00 at 14.8°N, 115°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Tropical Storm intensity with max winds of 25 m/s (~90 km/h) and a minimum central pressure of 990hPa, recorded at 1985-09-21 06:00:00.
1985-09-22 06:00:00 After, Typhoon Winona gradually weakened and was numbered off on 1985-09-22 06:00:00 was numbered off; its lifecycle recorded 14 track points.
Typhoon Winona (198517)'s life history is short, from formed to dispersed about 3 and a half days. Its initial position at S Sea Central waters (14.8°N, 115°E) , the overall Moving path presents a stable NW toward Trend. During September 19 to 20th, the systemins NamelessIntensity, with a relatively uniform step width toward NW direction advance, after latitude changes show its toward W movement percentage slightly larger at toward N upward percentage. Go to September 21st, with the latitude rising to 19.5°N, the path direction gradually turns to more perpendicular toward N, the W move speed slows, indicating that the guiding flow structure may be modest. Thro the process, Typhoon observed no noticeable path or
In terms of Intensity changes, Winona underwent a typical 'formed-enhanced-top-weakened' process. In the early September 19th, NamelessIntensity was stable at 12m/s. From the morning of September 20th, wind speed gradually increased to 15m/s, and at the evening increased to 17m/s. September 21st was the key reinforcement period of the system, the morning upgrade to Tropical Storm (20m/s) , and at 06:00 reached peak intensity, recognized as Severe Tropical Storm, max wind to 25m/s. The peak stateined about 12h, starting from 21:18:00, wind speed decreased to 23m/s, 20m/s, until the end of life fell back to 17m/s.
Compared with previously named Typhoon, Winona's peak intensity (Severe Tropical Storm, 25m/s) in 1985 was at a medium level. compared with at 1990 Winona (top Typhoon) and 1989 Winona (both called Severe Tropical Storm) in 1982 , its intensity was weak at 1990 system, but equal to the same name Typhoon in 1989 and 1982. while Winona in 1993 was only for Tropical Storm Intensity, so the intensity of the 1985 system was significantly high at 1993 case.
