摘要
2008年1月，我国南方大部地区遭受历史罕见的低温、雨雪、冰冻灾害，作者对此次天气气候过程进行了分析并与同期历史进行了比较。发现：此次冰冻天气影响范围广、强度大、持续时间长、造成的损失极为严重，全国有20个省（区、市）先后遭受了低温雨雪冰冻灾害，湖南、湖北大部、江西西北部、安徽中南部、贵州中部等地冰冻日数达10--20天；此次冰冻灾害强度大，表现为降温明显、日最高气温异常偏低、降水量显著偏多；持续时间长，长江中下游及贵州连续低温日数和连续冰冻日数均超过1954／1955年冬季，达到历史最大值；冰冻灾害对电力、交通运输、农业及人民群众生活造成严重影响和损失，尤其对我国南方电力运行造成灾难性影响。
During January 2008, a persistent process of severe weathers with cold surge, ice-snow and frozen rain attacked South China. These weather-related climate extremes and accessed their impacts on South China are reviewed. The analysis suggests that the cold surge and heavy snowfall jointly caused frozen weather and affected 20 provinces in South China, where, Hunan, Hubei, Jiangxi, Anhui, and Guizhou witnessed persistent frozen weathers of 10--20 days. It resulted in the most severe damage due to its powerful intensity and long time persistence in these areas, where the number of continuous low temperature days and frozen days broke through the record in the winter of 1954/1955 in the lower reaches of the Yangtze River region and Guizhou Province. These frozen weathers caused great damages through influencing transportation, agriculture, and people daily activities, particularly by stopping the power supply in South China.
