摘 要：
根据2001～2006年天气演变形势,分析了辽宁中部城市群受沙尘天气影响类型,发现共有4种沙尘天气类型,其中局地型最多见,主要原因是科尔沁沙地为其提供了充足的沙源。蒙古气旋携带上游沙尘过境,对中部城市群影响也很大,尤其配合其后部强冷空气影响时,沙尘对辽宁影响范围大、强度强、时间长。沙尘天气预报着眼点首先关注沙源地是否起沙;其次关注动力条件,包括气旋的生成和移动路径、冷暖平流、锋面的过境时间和产生大风的条件等;还要关注附近沙源地的气候条件;然后对照各影响天气型特点进行预测预报。

摘 要：
Based on weather evolvement situation from 2001 to 2006,the influence types of sand and dust weather in a group of cities in central Liaoning were analyzed. There were four kinds of sand and dust weather types and the local type appeared at best because of the strong dust source of Horqin sands. When Mongolia cyclone passed by with upriver dust,the cities was affected deeply. The dust would have a large-scale,high strength and lasting affection on Liaoning in the case of dust weather with strong cold air subsequent. The forecast of dust weather should base on the analyses of blown sand of dust source,the weather dynamical conditions such as forming and transfer of cyclone,advection,front,wind,the climate conditions around the dust source. The forecast could be done by comparing weather characteristic with the four kinds of dust weather types.
