摘要
利用喀什地区11个气象观测站1961～2003年地面观测气表-1资料,统计分析了局地性沙尘天气过程和区域性沙尘天气过程。普查33年历史天气图,对强区域性沙尘天气过程进行了500hPa环流形势分型。沙尘成因分析表明:南疆西部沙尘天气大多与冷空气活动有关,最后给出其预报着眼点。
By using the surface observational data of 11 meteorological stations in Kashi area of Xinjiang,the local and regional sand-dust weather processes were analyzed.Based on the historical weather map of 33 years,the 500hPa circulation situations of the heavy sand-dust weather processes were divided,and their forcasting indicators were given.
