乌鲁木齐机场一次连续性雷暴天气分析与气象服务保障

A continuous thunderstorm analysis and meteorological service at Urumqi Airport

摘要: 本文使用常规、卫星、雷达等资料对乌鲁木齐机场2014年8月21日一次连续性雷暴天气进行分析，结果表明此次雷暴由于中高层槽后干冷空气叠加在低层暖湿空气之上，从而具备有利的热力和动力条件导致。中尺度天气分析方法可以预测中小尺度强天气落区，但是中尺度数值预报模式缺乏有效的强对流天气指导产品。

Abstract: In this paper, the analysis of a continuous thunderstormat Urumqi airport on August 21, 2014 frombasic meteorological data, satellite and radar data showed that the air with upper-layer dry and lower-layer wetcreates the thermal and dynamic conditions.The mesoscale weather analysis can predict themesoscale weatherfalling area, but the mesoscale numerical model lacks effective convective weather guidance products.
