| 摘 要： | 利用高空与地面观测资料,主要从形势场、温度层结、地理形势及地面气象要素等方面,对庐山2008年和2009年两次冰冻天气过程进行对比分析。结果表明,庐山2009年冰冻灾害与2008年初中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。认为庐山冰冻灾害的出现主要决定于925—850hPa层次的温度层结,当层结温度降为0℃以下并伴有较明显降水时,并不一定需要太长时间和明显逆温层的存在庐山就可以出现冰冻灾害。

| Abstract: | Using observation data, two freezing weather events occurred in 2008 and 2009 of Lu Mountain are comparatively analyzed. The result shows that there are different characteristics between the two freezing rain events, and the 2009 event presents more obvious characteristics of Lu Mountain local feature. Lu Mountain freezing disaster occurs mainly depends on temperature stratification of 925--850 hPa levels. When the air temperature dropped to 0 ~C or below, and accompanied by significant rainfall, Lu Mountain freezing disasters can occur shortly without the existence of significant temperature inversion. |
