Typhoon Sanvu, international code 202301, international name Sanvu, 2023 Northwest Pacific typhoon. Formed: 2023-04-20 17:00:00, ended: 2023-04-22 17:00:00. Peak intensity: Tropical Storm, minimum central pressure: 992 hPa, max wind: 23m/s.
Typhoon Sanvu at 2023-04-20 17:00:00 at 9.1°N, 156.8°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Tropical Storm intensity with max winds of 23 m/s (~83 km/h) and a minimum central pressure of 992hPa, recorded at 2023-04-21 14:00:00.
2023-04-22 17:00:00 After, Typhoon Sanvu gradually weakened and was numbered off on 2023-04-22 17:00:00 was numbered off; its lifecycle recorded 13 track points.
2023年第1号Typhoon “Sanvu”的生命史较短, 主要活动区域位 at Northwest Pacific低The latitude洋面. 从观测数据来看, 该Typhoon formed at 2023年4月20日17时 (9.1°N, 156.8°E) , 至4月22日17时 weakened into Nameless (10.4°N, 154.8°E) , 全程未Landfall任何陆地. 在Moving路径上, “Sanvu”整体呈现缓慢的WNTrend. 初期 (20日至21日凌晨) , 其During从156.8°EW移至156.0°E, 纬度由9.1°NN抬至9.9°N, Moving速度相对平稳. Go to 21日上午后, Moving速度显著减缓, 特别是在21日14时至22日05时期间, Center几乎停滞在10.2°N-10.3°N, 155.6°E-155.3°E的狭小区域内, 表现出明显的准静止特征. 随后, 系统再次启动 toward WMoving, 直至消散. 这种先NW行, 后短暂停滞, 再W行的路径形态, 反映了引导气流在低纬度的复杂变化.
在Intensity方面, “Sanvu”经历了典型的“增强-维持-减弱”过程. formed初期Pressure为1000hPa, max wind 18m/s. 经过约21h的缓慢加强, at 21日14时达到peak intensity, 此时中心最低气压降至992hPa, max wind 增至23m/s, 等级维持为Tropical Storm. 巅峰状态持续了约15h, 期间气压和wind speed保持稳定. 22日08时起, 系统开始减弱, 气压回升至998hPa, wind speed降至20m/s, 最终在22日17时降级为Nameless, wind speed15m/s, 气压1002hPa.
Data show that the peak intensity of the 15th Typhoon “Sanvu” in 2017 and the 2nd Typhoon “Sanvu” in 2012 both reached the Typhoon level, the minimum pressure is 970hPa; the 10th Typhoon “Sanvu” in 2005 also reached the Severe Tropical Storm level, the minimum pressure is 975hPa.
