[Method] By means of meteorological data from automatic stations in southeastern Guizhou, the occurrence time, influence range and disaster intensity of freezing disaste from December 31st, 2010 to January 10th, 2011 were analyzed and compared with freezing disaster in January 2008. [Result] Freezing weather in January 2011 started early and strongly, with large influence rang, lower decrease and intermittent rising of temperature, and subsequent cold air was weak, so freezing disaster weakened gradually; in January 2008, freezing weather began later and lasted for a long time, and subsequent cold air strengthened gradually, while temperature went down gradually accompanying continuous rainfall (snowfall), so freezing disaster became more and more serious. In a word, freezing disaster in January 2008 was severer than that of 2011. [Conclusion] The study could provide scientific references for the prediction and early warning of freezing disaster and establishment of corresponding countermeasures.展开更多
