摘要
对2002年12月25～27日全区性寒潮天气过程爆发前后的形势进行分析,认为横槽南摆是造成这次过程的主要原因,而低纬度南支槽的配合加剧了过程的降温、降水;通过对数值预报产品的解释应用,得到一些预报全区性寒潮的指示信息。
The analysis of weather situation before and after the explosion of cold current weather in whole Guangxi during Dec. 25~27 in 2002 found out the southwards swing of transverse trough as the main cause for this weather process, while the co-action of south branch trough at low latitude strengthened the temperature drop and precipitation. The interpretation and application of numerical forecast products provide indicative information on cold current forecast.
