| 摘 要： | 该文利用多种气象资料（包括常规观测、卫星云图、自动气象站、多普勒气象雷达以及风廓线仪资料），综合分析了2002年8月24日发生在长江三角洲的一次飑线过程。发现该飑线产生于一个中尺度对流系统（MCS）当中，地面冷锋、副高边缘的高能水汽输送带与高空小槽配合，使该MCS得以发展和加强，副高南撤和下游有利的动力和层结条件使得MCS中的雷暴群发展为飑线，并迅速东移南压，产生了大范围雷雨大风天气。多普勒雷达、自动站及风廓线仪的资料还很好地揭示了该飑线的发生、发展、爆发过程及其回波和风场的空间结构特点。

| Abstract: | Based on many kinds of observations, including conventional data, cloud image, Doppler radar data and wind profiler data, a squall happened in the Yangtse River Delta on 24 August 2002 is analyzed. It is found that this squall was caused by a mesoscale convective system (MCS). Cold front, water vapor transportation beside the subtropical high and a 500 hPa trough made the MCS arise and enhance. The fading and moving southward of the subtropical high and the local advantaged dynamic and air-layer conditions caused the MCS expand to be a squall, and the squall moved rapidly southward and eastward and brought wind and thunderstorm. The squall's echo and wind structure are well figured out by Doppler radar, auto-station and wind profiler data. |
