Typhoon Caitlin, international code 199109, international name CAITLIN, 1991 Northwest Pacific typhoon. Formed: 1991-07-18 12:00:00, ended: 1991-07-30 00:00:00. Peak intensity: Severe Typhoon, minimum central pressure: 940 hPa, max wind: 48m/s.
Typhoon Caitlin at 1991-07-18 12:00:00 at 5°N, 157°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Typhoon intensity with max winds of 48 m/s (~173 km/h) and a minimum central pressure of 940hPa, recorded at 1991-07-27 18:00:00.
1991-07-30 00:00:00 After, Typhoon Caitlin gradually weakened and was numbered off on 1991-07-30 00:00:00 was numbered off; its lifecycle recorded 47 track points.
Typhoon Caitlin (199109) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW行—N转—NE移”的抛物线形态. formed初期 (7月18日至23日) , 系统位 at 低The latitude海域 (5°N-14°N) , 受副热带高压S侧引导气流影响, 稳定 toward NW, During从157°E快速W移至131.9°E. 7月24日至26日期间, 随着纬度提升至15°N以上, 路径逐渐由纯NW toward 转为N direction, Moving速度在接近20°N时略有调整.
关键的转 toward 点出现在7月27日至28日之间. 当Center到达26.1°N, 126.6°E附近时, Typhoon StopN进并开始在原地少动或微幅摆动, 随后受W风带槽前气流引导, 路径显著转 toward NE. 7月29日后, 系统加速 toward 高The latitude海域Moving, 最终 at 7月30日00:00在39.1°N, 133.4°E附近结束观测. 整个生命周期长达11.5天, track points达47个, 显示其结构维持Time较长, 且全程无Landfall记录, 主要在开阔洋面上活动.
Caitlin's Intensity evolution underwent a long period of enhancement. Starting from the 18th of July's Nameless (7m/s), the system slowly strengthened during the NW march, until July 24th upgraded to Tropical Storm (23m/s) . The real explosive enhancement occurred from July 25 to 28, in just three days, the max wind jumped from 30m/s to peak intensity of 48m/s, reaching Severe Typhoon level. It is noteworthy that during the 27th to 28th of July's route toward, despite the latitude rise, its Intensity remained at a height of 46-48m/s, showing stronger vertical wind switching capabilities.
Compared with the same name Typhoon, Caitlin's intensity was significantly high in 1991 at 13th Typehoon Caitlin in 1994.Typhoon's peak in 1994 was only Severe Tropical Storm, while Caitlin in 1991 not only reached the Severe Typhoon level, and Max Wind was up to 48m/s, both of which had significant differences in the intensity level, indicating that in 1991 the codeTyphoon had a stronger energy accumulation and a better core structure.
