The SummaryTyphoon Yanyan (international code 200301) is a 2003 Northwest Pacific typhoon; peak intensity Severe Tropical Storm, max wind 25m/s, minimum central pressure 987hPa, not in China Landfall, 2003-01-21 was numbered off, recorded 41 track points.
Typhoon Yanyan, international code 200301, international name YANYAN, 2003 Northwest Pacific typhoon. Formed: 2003-01-11 12:00:00, ended: 2003-01-21 12:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 987 hPa, max wind: 25m/s.
Typhoon Yanyan at 2003-01-11 12:00:00 at 1.9°N, 179.6°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 987hPa, recorded at 2003-01-18 18:00:00.
2003-01-21 12:00:00 After, Typhoon Yanyan gradually weakened and was numbered off on 2003-01-21 12:00:00 was numbered off; its lifecycle recorded 41 track points.
Typhoon Yanyan (200301)'s life history began at the low latitude waters near the international date change line, the overall path showing a significant NW toward MovingTrend, then turning toward NE direction dispersed. From the initial formed point (1.9°N, 179.6°E) to January 17, the system was mainly influenced by guided airflow, stable toward NW direction.
值得注意的是, 该系统在1月19日前后出现了明显的路径转折. 1月19日00:00位 at 14.5°N, 148.2°E时达到最W端Position, 随后路径开始 toward E偏转. 至1月21日终止时, Center移至18.5°N, 156.9°E. 这种先NW后NE的抛物线型路径, 符合热带气旋在副热带高压边缘Moving的典型特征. 整个生命周期持续10天, track points分布均匀, 未出现停滞或打转现象, Moving速度相对平稳.
Yanyan的Intensity演变经历了缓慢增强, 快速爆发及迅速减弱三个阶段. formed初期至1月17日, 系统长期维持Nameless等级, wind speed在7-15m/s之间波动, 气压在1000-1006hPa区间徘徊, 显示出组织结构的松散性. 真正的增强发生在1月18日至19日, 短短一天半内, max wind 从15m/s跃升至25m/s, 中心最低气压降至987hPa, 等级由Nameless连跳两级至Severe Tropical Storm, 达到生命史巅峰.
After 18:00 on January 19, the system rapidly weakened, wind speed dropped back to 20m/s below, air pressure recovered. by January 21, before dispersal, has degraded back to the Nameless standard (10m/s, 1004hPa) . As the first codeTyphoon in 2003, its peak intensity was only for Severe Tropical Storm, far lower at the subsequent possible Super Typhoon level, and no landfall record, belonging to the typical ocean-formed, extinct weak Typhoon system.
