【摘要】 利用天气形势场、温度场、庐山站与周围站要素等资料,对2008和2009年两次冰冻过程进行对比分析,结果表明:1.2009年冰冻灾害与2008年初我国南方出现的大范围冰冻灾害有些不同特点,2009年冰冻灾害更具有明显的庐山局部性特征。2.庐山冰冻灾害的出现主要决定于925-850hpa层次的温度层结,当温度降至0℃以下并伴有较明显的降水时,庐山站并不一定需要太长时间和明显逆温层的存在就可以出现冰冻灾害。预报着眼点应主要从这两个方面进行考虑。更多还原

【Abstract】 By means of weather topographical field,temperature field and Lu Shan factors and its surrounding stations’ ones,analysis on the two processes of frozen weather compared 2008 yr with 2009yr was conducted,it shows that(1) frozen disaster in 2009 is different from one happened to Sothern region in 2008,which has more obviously local feature.(2) frozen disaster happened to Lushan depends main on temperature stratification ranging from 925 to 850 Hpa,as temperature belows zero degree accompanied obvious rainfall,there are no needs for too long timesand obvious thermal inversion in Lushan,which are forecast focus.更多还原
