| 摘 要： | 利用常规天气资料、卫星云图资料、乌鲁木齐市多普勒雷达资料、AWOS资料对乌鲁木齐机场2006年5月18日发生的一次小尺度天气带来的强雷暴进行分析，结果表明：雷暴天气发生在较强降水过程之后较低气温条件下的一次特殊天气。雷暴天气发生时，乌鲁木齐机场个别时刻跑道两端出现了风向和风速变化的不连续，在跑道上形成了水平风切变。此次雷暴天气是在北疆地区存在高空急流及500hPa高空槽的特定大尺度天气背景下，由地面能量锋、地面辐合线、干线触发的强对流天气。

| Abstract: | On the basis of analysis of Doppler radar data, combined with routine synoptic analysis data and satellite data and AWOS data, the mechanism of the deep convection weather at the Urumqi Airport on May 18th 2006 were investigated. It is shown that the deep convection weather occurs at lower temperature conditions after stronger rainfall process. When thunderstorm weather occur, the wind speed and wind direction at the both ends of runway appear discontinuity, and form level wind shear on the runway. This thunderstorm was a deep convection weather, to be touched off by surface energy front, surface convergence line and dry line with the specific large-scale weather background such as the upper jet and 500hPa upper trough in northern Xinjiang. |
