The SummaryTyphoon Krosa (international code 202509) is a 2025 Northwest Pacific typhoon; peak intensity Typhoon, max wind 35m/s, minimum central pressure 970hPa, not in China Landfall, 2025-08-03 was numbered off, recording 85 track points.
Typhoon Krosa, international code 202509, international name KROSA, 2025 Northwest Pacific typhoon. Formed: 2025-07-24 11:00:00, ended: 2025-08-03 23:00:00. Peak intensity: Typhoon , minimum central pressure: 970 hPa, max wind: 35m/s.
Typhoon Krosa at 2025-07-24 11:00:00 at 14.4°N, 143.7°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Typhoon intensity with max winds of 35 m/s (~126 km/h) and a minimum central pressure of 970hPa, recorded at 2025-07-27 17:00:00.
2025-08-03 23:00:00 After, Typhoon Krosa gradually weakened and was numbered off on 2025-08-03 23:00:00 was numbered off; its lifecycle recorded 85 track points.
Typhoon Krosa (202509) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现显著的“先N后NE”转 toward 特征. formed初期 (7月24日至26日) , 系统位 at 143°E附近, The latitude从14.4°N缓慢N移至17.8°N, During变化极小, 表现为近乎垂直的N toward Moving, 移速较慢. 7月27日是路径的关键转折期, 随着Intensity迅速增强至Typhoon 级, 其Moving direction开始由正N逐渐 toward NE偏移, 经度从143.6°E toward E推进至145.6°E.
Go to maturity (July 28-30) , Typhoon at 27°N-29°N, 142°E-144°E has a short W fall and stagnation phenomenon, then re-accelerated toward NE. After August 1, the system fully Go to W wind belt guided air flow control zone, the path turned to a stable NE toward extension, the latitude rapidly climbed to 41.5°N, the length significantly moved E to 159°E.
Krosa的Intensity演变经历了“快速增强—巅峰维持—波动减弱”的过程. 从7月24日的Tropical Storm (18m/s, 1002hPa) 起步, 系统在48h内快速加强, at 7月27日23时达到巅峰状态, 中心最低气压降至970hPa, max wind 达35m/s, 定性为Typhoon 级. 巅峰状态维持Time较短, 随后受高The latitude环境因素影响, intensity 开始波动下降. 值得注意的是, 在8月1日至2日期间, 尽管纬度已高达32°N-36°N, 系统仍一度重新加强至Severe Tropical Storm级别 (25-28m/s) , 显示出较强的生命力, 直至8月3日末才彻底 weakened into Tropical Storm.
Historical data show that the KrosaTyphoon peak intensity in 2001, 2007, 2013 and 2019 reached the Severe Typhoon or Super Typhoon level, minimum pressure between 925hPa to 950hPa, max wind far greater than this year's 35m/s.
