摘要
利用常规天气资料及数值预报产品资料,对2010年宁夏北部地区首场寒潮天气过程从天气实况、成因、预报等几个方面进行了分析.结果表明,此次寒潮天气过程是在前期强烈增温的条件下,较强冷空气下沉入侵造成的;850 hPa冷暖平流与地面增降温有很好的对应关系.
On the basis of daily observation data and mathematical forecast data, weather process of the first cold wave of northern region of Ningxia in 2010 was analyzed form the live weather, causes and prediction of and more. The result shows that the cause of cold wave weather is for the invasion of strong cold advection which under the conditions of intense heat before; there is correspondence between warm and cold advection in 850hPa and the increase and decline of ground temperature.
