增暖背景下武汉地区雾的变化特征

利用1951～2002年的地面气象资料，计算分析了武汉地区年、月平均气温、最高气温、最低气温的气候倾向率，揭示了武汉地区气候变暖的主要特征；对武汉地区雾日和雾的生成、消散以及相关气象要素进行了统计分析，阐述了武汉市雾日的年际和月际变化规律，雾的生、消变化规律。强度变化规律；通过武汉年平均气温与雾日的小波变换分析，认为雾日变化与气温变化具有相反的年代际气候特征，增暖背景下武汉地区雾是减少的。

Analysis of Fog Variation Characteristics in Wuhan under Warming Climate

By means of ground meteorological data from 1931 to 2002, the climatic tendencies of annual and monthly mean temperature, maximal and minimal temperature in the Wuhan region were analyzed. A statistic analysis was made of foggy days, fog formation and dissipation, and the correlated meteorological factors. The regularities of annual and monthly fog variation, fog formation and dissipation, and fog intensity were discussed. The annual mean temperature and foggy days of Wuhan were analyzed using the wavelet analysis technique. The results indicate that there were opposite inter-decade variation characteristics between foggy days and annual mean temperature
