| 摘 要： | 提出了三峡地区强降温过程的标准，利用宜昌台１９５２￣１９９５年逐日气温，降水资料、统计了历年９月￣次年４月强降温过程出现的次数，分析了强降温过程温度状况与年际变化等天气过程的气候规律，分析特别指出：从年代际来看，自８０年代起，９月、１２月和１月份强降温过程次数明显减少，强冷空气活动少，致使近年来宜昌地区连续出现暖冬天气。

| Abstract: | The standard of strong detemperature in the Three Gorges area of Yangtze River is proposed. Using day by day temperature data of Yichang weather station from 1952 to 1995, the number of detemperature process is counted and the interannual change character is analysed. Evidence suggests that since the eighties,the number of strong detemperature process has decreased in September, December and January. As the strong cold air activity become weaker the Yichang area has experienced several warm winters in succession in recent years. |
