Typhoon Roger, international code 198919, international name ROGER, 1989 Northwest Pacific typhoon. Formed: 1989-08-22 18:00:00, ended: 1989-08-28 12:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 975 hPa, max wind: 25m/s.
Typhoon Roger at 1989-08-22 18:00:00 at 26.3°N, 121.6°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 975hPa, recorded at 1989-08-27 00:00:00.
1989-08-28 12:00:00 After, Typhoon Roger gradually weakened and was numbered off on 1989-08-28 12:00:00 was numbered off; its lifecycle recorded 24 track points.
Typhoon Roger (198919) 的生命周期始 at 1989年8月22日18时, 终 at 8月28日12时, 全程未Landfall陆地. 从空间轨迹来看, 该Typhoon 呈现出显著的“先W后NE”的折线型Moving特征. formed初期 (8月22日至24日) , 系统位 at lat 25°至26°N, 121°至124°之间, 主要 toward W direction缓慢Moving, The latitude略有下降, During稳步增加. 8月25日是一个关键的转折过渡期, 系统在维持NamelessIntensity的同时, Moving direction开始由W转为NW, 随后迅速转 toward NE.
Go to August 26, the Typhoon accelerated toward NE, the latitude rapidly climbed from 24.8°N to 44.8°N, the length extended from 125.6°E to 143°E. Especially in the 12h of August 26 at 06:00 to 18:00, the latitude increased by about 3.5 degrees, showing the influence of the wind belt guided air flow significantly, the Moving speed significantly accelerated.
In terms of Intensity changes, Typhoon Roger's overall Intensity is weak, the peak level is only Severe Tropical Storm, max wind 25m/s. The system in the first half of August 22 to 25 18 am has longined the Nameless state, wind speed fluctuates between 12m/s to 17m/s, the enhancement process is slow. until August 26 at 06 am, with the PositionN move, the system has intensified into Tropical Storm, wind speed reaches 20m/s, and at the same day at 18 am reaches the peak wind speed 23m/s. Since then, although the latitude continues to rise significantly, but wind speed remains at about 20m/s until disappearing, no further explosion enhancement has been seen, indicating that its structure may be restricted by vertical wind cuts or
Historical records show that Roger had reached the Super Typhoon level in 1979, and Roger also reached the Typhoon and Severe Typhoon levels in 1982 and 1986 respectively.
