The SummaryTyphoon Orchid (international code 199121) is a 1991 Northwest Pacific typhoon; peak intensity Super Typhoon, max wind 59m/s, minimum central pressure 930hPa, not in China Landfall, 1991-10-13 was numbered off, recording 49 track points.
Typhoon Orchid, international code 199121, international name ORCHID, 1991 Northwest Pacific typhoon. Formed: 1991-10-01 00:00:00, ended: 1991-10-13 00:00:00. Peak intensity: Super Typhoon, minimum central pressure: 930 hPa, max wind: 59m/s.
Typhoon Orchid at 1991-10-01 00:00:00 at 13.6°N, 149.2°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 59 m/s (~212 km/h) and a minimum central pressure of 930hPa, recorded at 1991-10-07 06:00:00.
1991-10-13 00:00:00 After, Typhoon Orchid gradually weakened and was numbered off on 1991-10-13 00:00:00 was numbered off; its lifecycle recorded 49 track points.
Typhoon Orchid (199121) 的生命周期始 at 1991年10月1日, formed at Northwest Pacific远洋海域 (13.6°N, 149.2°E) , 初始状态为Nameless. 在 formed初期至10月5日期间, 系统整体呈现稳定的W行Trend, The latitude从13.6°N缓慢N抬至19.2°N, During则由149.2°E大幅W移至136.2°E, 横跨约13个经度. 这一阶段Moving路径较为平直, 受副热带高压引导气流影响显著.
When the system center arrived near 133.6°E, its W-line speed significantly slowed, and on 7 October reached the most W-side Position (131.4°E) . Subsequently, the path appeared a noticeable reverse clock turn toward characteristic, the system began toward NE. After 9 October, the Typhoon accelerated toward NE, the latitude rapidly climbed from 24.1°N to 33.6°N on 13 October, the length also returned to 142.7°E. The entire path showed a typical 'spinning line' trajectory, without Landfall any land, and eventually weakened dispersion in the far ocean.
在Intensity变化方面, Orchid经历了完整的生命史演变. 从10月1日的7m/sNameless起步, 系统在W行过程中持续整合能量, at 10月5日增强为Severe Tropical Storm (25m/s) , 次日进一步发展为Typhoon (35m/s) . 爆发式增强出现在10月7日, wind speed骤升至56m/s, 达到Super Typhoon级别, 并在此Intensity维持至10月8日. 数据显示, 其巅峰Max Wind达到59m/s, 体现了极强的核心对流活动.
On October 9, wind speed dropped to 51m/s, stillining the Super Typhoon level; on October 10, it dropped to Typhoon level (41m/s); and on October 12, weakened into Severe Tropical Storm (30m/s), finally at October 13, wind speed at 28m/s.
Compared to the Severe Typhoon level in 1987 (198701) and the Severe Typhoon level in 1980 (198013) and the Super Typhoon level in 1994 (199427) Orchid also reached the Super Typhoon level in 1991 and Max Wind59m/s showed its extremely high destruction potential, although it did not cause landfall disasters, but its oceanic Intensity evolution characteristics were quite representative in the same period Typhoon.
