摘要
利用天气学方法对2003年1月3-5日山东半岛北部地区的一次强降雪过程进行了分析。结果表明:强降雪发生前,山东半岛北部地区低层大气湿度增大;在有利的大尺度环流条件下,受暖海面的热力作用和地形抬升作用,产生中尺度海岸锋,中尺度海岸锋造成局地降雪的增强。
Based on the Dynamic analysis of a snow storm event in 3-5 January 2003 in Shandong Peninsula by using the meteorological method ,we have a result that: before the snow storm , relative humity in the low layer atmosphere got higher and higher, at last the vapoure was nearly sturatde. In the favorable large-scale air circulation, both thermodynamic instability caused by the warm sea and dynamic forcing by the Laishan ridge, produce meso-scale coast, which can bring an obvious increace of snowfall intensity in the region of the north. of Shandong Peninsula
