Typhoon Mac, international code 198604, international name MAC, 1986 Northwest Pacific typhoon. Formed: 1986-05-22 06:00:00, ended: 1986-05-29 12:00:00. Peak intensity: Tropical Storm, minimum central pressure: 992 hPa, max wind: 23m/s.
Typhoon Mac at 1986-05-22 06:00:00 at 19.8°N, 112.9°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 992hPa, recorded at 1986-05-26 06:00:00.
1986-05-29 12:00:00 After, Typhoon Mac gradually weakened and was numbered off on 1986-05-29 12:00:00 was numbered off; its lifecycle recorded 30 track points.
Typhoon Mac (198604) 的生命史始 at S海N部海域, 整体路径呈现稳定的NE toward MovingTrend. formed初期 (5月22日至23日) , 系统位 at lat 19.6°至20.0°N, 112.9°至116.1°之间, 主要受引导气流影响 toward E direction缓慢Moving, The latitude变化极小. Go to 5月24日后, 路径逐渐转为NE direction, 穿越Taiwan海峡S部及巴士海峡W侧海域. 值得注意的是, 该Typhoon 全程未Landfall任何陆地, 始终在海上活动.
From coordinate sequence analysis, during May 26-27, the Typhoon center latitude rapidly increased from 21.3°N to 23.5°N, the length shifted from 121.7°E to 123.3°E, showing noticeable accelerated N-shift characteristics. Subsequently, on May 28-29th, the system continued toward NEward direction deep into the Northwest Pacific ocean, and finally at May 29th at 12.12 at 24.9°N, 130.9°E weakened dispersal.
In terms of intensity, Typhoon Mac overall weak, peak intensity is only for Tropical Storm level. May 22 to 24, the systemins Nameless state, max wind is stable at 12m/s. May 25 wind speed increased to 15m/s, and at May 26 at 06 am reached the strongest state in life history, max wind is 23m/s, confirmed that Tropical Storm level. Since then, with the system toward NMoving and Go to higher latitude waters, environmental conditions tend at adverse, intensity begins to fluctuate. May 27 at 06wind speed dropped to 20m/s, at 18am the same day returned to the Nameless standard (17m/s), until dispersion has beenined in the 12-15m/s Nameless area.
Compared to the same name History, the 1986 Mac Intensity is significantly weaker.Return to previous data, the 1990 Mac (199025) had developed into Super Typhoon, the 1989 Mac (198914) and the 1979 Mac (197913) both reached the Typehoon level.
