摘　　要：采用1971~2013年双鸭山逐日天气现象资料,利用线性倾向估计法分析双鸭山雾、霾天气的气候特征。分析表明：双鸭山雾、轻雾年发生日数为减少趋势,上世纪70~80年代发生最多,霾很少发生;雾、轻雾一年各月均有发生,雾夏季最多,轻雾冬季最多;雾发生多在08~09时,雾消多在09~10时,持续时间多小于2小时。Based on the daily weather data from 1971 to 2013 in Shuangyashan, the climatic characteristics of tog and haze days were analyzed by using the method of linear trend estimation. The results show that the annual fog and mist days are decreased, while haze days occur rarely. The most fog and mist days occur in 1970s and 1980s. Fog and mist days occur in each month of the year. The most average fog days are in summer, while the most average mist days are in winter. The fog often occurs during 8 AM to 9 AM and disappears during 9 AM to 10AM in a day. The duration of fog lasts less than 2 hours.
