乌鲁木齐机场一次中雨天气过程特征分析
Analysis of Characteristics of a Moderate Rain Weather Process at Urumqi Airport
摘要: 分析了2024年7月19日乌鲁木齐机场的一次降雨天气的成因与特征，发现了本次降雨过程呈现积层混合云降水的特征，乌鲁木齐机场上空从近地面至200 hPa均为上升运动，乌鲁木齐机场本地有充足的水汽条件，降雨的水汽输送通道主要为中亚低涡底部分裂的短波槽，乌鲁木齐机场上空中低层有强的水汽辐合。良好的水汽条件和长时间外地的水汽输送是本次降雨总时间长、中雨时段长的主要原因。
Abstract: An analysis was conducted on the causes and characteristics of a rainfall event at Urumqi Airport on July 19, 2024, and it was found that the rainfall process exhibited the characteristics of layered mixed cloud precipitation. The airspace above Urumqi Airport was in an upward motion from near ground to 200 hPa, and there were sufficient water vapor conditions locally at Urumqi Airport. The main water vapor transport channel for rainfall was the short wave trough at the bottom of the Central Asian vortex, and there was strong water vapor convergence in the lower atmosphere above Urumqi Airport. The good water vapor conditions and long-term water vapor transport from other places are the main reasons for the long total duration and moderate rain period of this rainfall.
