The SummaryTyphoon Koryn (international code 199001) is a 1990 Northwest Pacific typhoon; peak intensity Typhoon, max wind 38m/s, minimum central pressure 980hPa, not in China Landfall, 1990-01-17 was numbered off, recording 40 track points.
Typhoon Koryn, international code 199001, international name KORYN, 1990 Northwest Pacific typhoon. Formed: 1990-01-08 00:00:00, ended: 1990-01-17 18:00:00. Peak intensity: Typhoon , minimum central pressure: 980 hPa, max wind: 38m/s.
Typhoon Koryn at 1990-01-08 00:00:00 at 1.3°N, 172°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 38 m/s (~137 km/h) and a minimum central pressure of 980hPa, recorded at 1990-01-15 00:00:00.
1990-01-17 18:00:00 After, Typhoon Koryn gradually weakened and was numbered off on 1990-01-17 18:00:00 was numbered off; its lifecycle recorded 40 track points.
Typhoon Koryn (199001) 的生命史始 at 1990年1月8日, formed at Northwest Pacific低The latitude海域 (1.3°N, 172°E) . 在初始阶段, 系统整体呈现稳定的W行Trend. 从1月8日至1月13日, Typhoon 中心纬度由1.3°N缓慢N抬至10°N, During则从172°E持续W移至147.5°E, 表明其主要受低层信风引导, toward NW. 值得注意的是, 1月14日至1月15日期间, 系统在达到peak intensity后, 经度变化极小 (145.8°E至145.9°E) , 显示其在145°E附近出现短暂的停滞或打转现象. 随后, 路径发生显著转折, 自1月16日起, 系统转 toward NE direction加速Moving, 经度迅速E退至165°E, 纬度N抬至29.6°N. 整个生命周期内, 该Typhoon 未Landfall任何陆地, 始终在洋面上活动, 最终 at 1月17日18时在高纬度海域减弱消散.
在Intensity变化方面, Koryn经历了典型的“缓慢增强-快速爆发-迅速减弱”过程. formed初期至1月13日, 系统长期维持Nameless等级, wind speed在7m/s至17m/s之间波动, 增强节奏较为平缓. 1月14日, intensity 出现跃升, 短短一天内由Severe Tropical Storm (30m/s) 发展为Typhoon (35m/s) , 并 at 当日18时达到peak intensity, max wind 录得38m/s. 然而, 巅峰状态维持Time较短, 1月15日后wind speed开始回落, 至1月17日已 weakened into Tropical Storm. 与同名Typhoon 相比, 1993年的第2号Typhoon Koryn peaked at Super Typhoon级别, 显著强 at 1990年的这例Typhoon . 1990年Koryn虽然达到了Typhoon 级标准, 但其在低The latitude海域的酝酿期较长, 且peak intensity后的衰减速度较快, 显示出其能量获取与环境场配合的局限性.
