Typhoon Holly (198409) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW—N—NE”抛物线型转 toward 特征. formed初期 (8月14日至16日) , 系统自137.6°E附近 toward NW direction稳定Moving, The latitude从19.3°N迅速N抬至22.8°N, DuringW移约6.5个经纬度, 显示其受副热带高压S侧引导气流影响显著.
As the system N rises to 23°N by N, the Moving direction gradually shifts from pure NW to N, followed by around 12:00 on August 19, when the Center reaches 27.7°N, 126.5°E, the path shows obvious signs of reversal.
在Intensity变化方面, Holly经历了完整的“ formed—增强—巅峰—减弱”过程. 从8月14日的Nameless (12m/s) 起步, 系统持续加强, at 8月18日00:00在23.6°N附近升级为Typhoon 级别 (33m/s) . peak intensity出现在8月19日12:00至8月20日12:00期间, max wind 维持在38m/s, 并在此高Intensity状态下保持了约36h, 显示出较强的结构稳定性. 8月21日后, 随着The latitude升高至33°N以上, 受高纬冷海水及风切变影响, intensity 迅速衰减, 由Typhoon 级降为Severe Tropical Storm, 最终 weakened into Tropical Storm后 was numbered off.
In comparison with the same name History, Holly's Intensity in 1984 between two other cases. the 1981 same name Typhoon is only for Tropical Storm level, intensity is weaker; while the 1987 same name Typhoon reached Super Typhoon level, destructive strength.
