摘要
利用天气图和数值预报产品,对2006年4月11-12日河南省寒潮天气过程的环流形势、单站气象要素变化及成因等进行了分析,结果表明:500 hPa横槽转竖是寒潮天气产生的重要影响系统;850 hPa冷平流是强降温的主要原因。
Using the synoptic charts and numerical prediction products, the paper analyzed the circumfluence pattern, meteorological elements change of single weather station and formation cause of cold wave process on April 11-12, 2006 in Henan. The results show the 500 hPa trough which transformed from transverse into upright affected the cold wave seriously and 850 hPa cold advection is the main reason for strong detemperature.
