Typhoon Dot, international code 197904, international name DOT, 1979年Northwest PacificTyphoon . formedTime: 1979-05-06 00:00:00, 结束Time: 1979-05-17 00:00:00. peak intensity: Tropical Storm, 最低Pressure: - hPa, max wind : 20m/s.
Typhoon Dot at 1979-05-06 00:00:00 at 4°, lng 147.5° over the Northwest Pacific; initial intensity: Nameless.
It peaked at Tropical Storm intensity with max winds of 20 m/s (~72 km/h) and a minimum central pressure of -hPa, recorded at 1979-05-13 18:00:00.
Typhoon Dot gradually weakened and was numbered off on 1979-05-17 00:00:00 was numbered off; its lifecycle recorded 45 track points.
Typhoon Dot (197904) 的生命史始 at 1979年5月6日, formed at Northwest Pacific低The latitude海域 (4°N, 147.5°E) . 在初始阶段, 系统呈现稳定的W行Trend, 从147.5°E迅速 toward WMoving至134.2°E附近, 期间纬度变化较小, 维持在4°N至5°N之间. 5月9日后, 路径出现显著转折, 系统开始 toward NW, 并逐渐 toward N分量增加. 值得注意的是, 该Typhoon 在接近Philippines以E洋面时 (约119°E-121°E区间) , 并未继续深入陆地或近海, 而是在12日至14日期间经历了一次明显的路径摆动: 先 toward W触及119.5°E, 随后转为NE. 最终, 系统在5月17日消散 at 22.2°N, 133°E附近. 整个生命周期长达11天, track points多达45个, 显示其结构维持Time较长, 但始终未Landfall任何陆地, 属 at 典型的远洋型热带气旋.
From the Intensity data, Typhoon Dot overall Intensity is weak, peak intensity is only for Tropical Storm intensity with max winds of as 20m/s. The system in the formed initial maintain Nameless state, wind speed fluctuates between 7m/s to 12m/s. May 10 wind speed briefly increased to 15m/s, then on May 13 reached peak intensity 17m/s, close to the lower limit of Tropical Storm, but until the end of life did not break the strong wind threshold of 20m/s, and the full range of air pressure data is missing, can not further confirm its core intensity by air pressure gradients.
Historical records show that the Typhoon Dot in 1985, 1989, 1990 and 1993 both reached the Typhoon even Super Typhoon level, of which the 1985 Dot minimum air pressure dropped to 895hPa, 1989 Dot also reached 955hPa.
