摘　　要：基于寿光市1961~2018年“三伏”时节气温、湿度观测资料,利用现代气候诊断方法,统计分析了寿光“三伏”时节气温、湿度要素的变化特征。结果表明: 1) 寿光市1961~2018年初、中伏气温高,高温日数出现频次大;2) 寿光近58年“三伏”平均气温比最高气温升温更显著,中伏比初伏和末伏升温更显著;相对湿度随年代下降显著,并通过0.01显著性检验;3) 40天“三伏”序列中,初伏中后期到后中伏中期,高温高湿;4) 进入21世纪以来,寿光中伏升温、湿度减小的趋势明显。Based on the observation data of temperature and humidity during the dog-days season in Shouguang City from 1961 to the beginning of 2018, the variation characteristics of temperature and humidity elements during the dog-days season in Shouguang City were statistically analyzed by using modern climate diagnosis method. The results showed that: 1) The frequency of high temperature days in Shouguang from 1961 to 2018 was high in medium dog-days temperature;2) The average temperature of the dog-days in Shouguang in recent 58 years was more significant than that of the maximum temperature, and the temperature of the middle dog-days was more significant than that of the first and last dog-days;the relative humidity decreased significantly with age and passed the significance test of 0.01;3) In the 40-day dog-days sequence, high temperature and high humidity occur from the middle and late period of primary to the middle period of post-middle period;4) Since the beginning of the 21st century, the trend of temperature rise and humidity decrease is obvious in Shouguang.
