【Abstract】 Based on winter freezing damage criteria, the law and influence factors of freezing damage in Guangxi are analyzed by using the information of day to day extreme low air temperature in winter (December ~ February) observed by 88 meteorological observation stations during1959~2000. The mathematical statistic method is adopted to analyze the relations of monthly mean height field of 500hPa in the Northern Hemisphere and the Pacific marine temperature field with the winter freezing damages in Guangxi.更多还原
