Typhoon Kirogi, international code 201725, international name Kirogi, 2017 Northwest Pacific typhoon. Formed: 2017-11-16 23:00:00, ended: 2017-11-19 17:00:00. Peak intensity: Tropical Storm, minimum central pressure: 998 hPa, max wind: 20m/s.
Typhoon Kirogi at 2017-11-16 23:00:00 at 7.3°N, 123.1°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Tropical Storm intensity with max winds of 20 m/s (~72 km/h) and a minimum central pressure of 998hPa, recorded at 2017-11-18 11:00:00.
2017-11-19 17:00:00 After, Typhoon Kirogi gradually weakened and was numbered off on 2017-11-19 17:00:00 was numbered off; its lifecycle recorded 23 track points.
Typhoon Kirogi (201725) 的生命史较短, 从 formed到消散历时约66h. 其路径整体呈现稳定的WN走 toward , 未出现明显的转 toward 或回旋现象. 初始阶段 (11月16日23时至17日08时) , 系统位 at Philippines以E洋面 (约123°E-119°E) , toward NW direction快速Moving, The latitude从7.3°N迅速提升至9°N. Go to S海中部后 (11月17日14时至18日20时) , Moving direction逐渐转为正W略N, During从118.2°E平稳推进至112°E, 纬度维持在10°N至11.6°N之间窄幅波动. 值得注意的是, 在11月19日02时至05时期间, 中心纬度出现短暂S落 (从11.8°N降至10.5°N) , 随后再次N抬, 表明后期受环境流场影响, 路径出现轻微摆动. 整个过程中, Typhoon 始终保持在海上活动, 无Landfall记录, 最终 at 11月19日17时在VietnamE部近海 (108.8°E, 11.6°N) weakened into Nameless并结束监测.
Kirogi的Intensity变化表现为“缓慢增强, 短暂维持, 迅速减弱”的特征. formed初期为Nameless, Pressure1007hPa, max wind 15m/s. 在 toward WMoving过程中, 气压缓慢下降, at 11月18日05时 intensified into Tropical Storm (18m/s, 1000hPa) . 11月18日11时达到peak intensity, 此时中心最低气压为998hPa, max wind 20m/s. 巅峰状态维持Time较长, 从11月18日11时至19日11时, 气压稳定在998-1000hPa区间, wind speed保持20m/s. 11月19日14时起, 系统迅速 weakened into Nameless, wind speed降至16m/s, 气压回升至1003hPa, 显示其结构在生命末期快速瓦解.
Its peak air pressure (998hPa) is equal to that of Kirogi (201212) but weak at 2023 Kirogi (202312, Severe Tropical Storm, 980hPa) , 2005 Kirogi (200520, Severe Typhoon, 940hPa) and 2000 Kirogi (200003, Super Typhoon) .
