Characteristics of Typhoon Chebi
Track and Movement Characteristics
2013年第9号Typhoon “Chebi”的生命史始 at S海E部海域, 整体路径呈现稳定的NW toward MovingTrend. 从7月31日02:00 formed时的初始Position (14.7°N, 116.3°E) 至8月3日20:00消散 at 中越边境附近 (22.3°N, 105.3°E) , 其Moving轨迹连贯, 未出现明显的路径突变或大范围回旋. 在 formed初期, 系统以Tropical DepressionIntensity toward WNW direction缓慢Moving; Go to 8月后, 随着纬度逐渐升高, Moving direction调整为更为纯粹的NW toward . 值得注意的是, 在接近Hainan岛及Landfall前后, Typhoon 中心维持了较为稳定的移速, 经纬度变化均匀, 表明其受引导气流影响显著且稳定. 该Typhoon 先后两次Landfall, 首次 at 8月2日19:30在Hainan文昌龙楼镇Landfall, 随后穿越琼州海峡或N部湾区域, 最终 at 8月3日10:00在中越边境完成第二次Landfall并迅速减弱消散.
Intensity evolution and historical comparison
Regarding intensity changes, Chebi intensified from a tropical depression to a severe tropical storm, reaching its peak before landfall. Data shows the system reached its strongest state at 16:00 on August 2, with the central minimum pressure dropping to 980 hPa and maximum winds reaching 30 m/s, classified as a severe tropical storm. Subsequently, due to land friction and cut-off moisture supply after making landfall in Hainan and moving inland, the intensity decreased in steps: wind speeds remained around 28 m/s after landing in Hainan; upon entering Guangxi and Vietnam, the pressure rose above 995 hPa and wind speeds rapidly dropped to 20 m/s or below, until it finally weakened into a tropical depression.
Compared with historical typhoons of the same name, the 2013 Chebi was significantly weaker. In contrast to the 2018 Chebi (peak super typhoon, minimum pressure 905 hPa) and the 2001 Chebi (peak super typhoon, minimum pressure 944 hPa), the 2013 system's peak pressure was nearly 80-100 hPa higher, indicating a huge difference in magnitude. Even compared to the 2024 Chebi (peak severe tropical storm, minimum pressure 985 hPa), the 2013 Chebi had a slightly lower minimum pressure by 5 hPa and slightly higher maximum winds, showing that while it was slightly stronger within the same category, it remained a tropical cyclone of moderate overall intensity.
