| 摘 要： | 利用ECMW F客观分析格点资料对2008年1~2月历史罕见的低温雨雪冰冻天气过程与183例广西大范围霜冻天气过程前一天20时的环流、气象要素作了合成后的对比、统计分析,结果表明:造成两种低温寒害过程的南下冷空气都在相同强度以上,都有一定程度的东亚槽引导。但由于形成条件不同,两种低温寒害过程在500hPa高度场、地面气压场、低层850hPa风场、温度场、湿度场存在较大差异。

| Abstract: | Based on the ECMWF data,the circulation and meteorological elements of the rare severe chilling icy rain and snow freezing and widespread frost disaster weather events are analyzed.Results show that these two kinds of weather both are similar within an Asian tough.Besides the conditions to shape these two weather are different on the view of height at 500hPa,suface pressure,wind field at 850hPa and humidity. |
