摘要
选取1960-2010年霍山县的逐日气温和降水数据资料,采用统计法和线性回归分析法,分析了霍山县1960-2010年气温和降水的变化特征。结果表明:1960-2010年时期内,霍山县的年平均温度和年总降雨量都表现为上升的趋势,其中,温度的增长速率为0.177℃/10a,降雨量的增长速率为28.17mm/10a,降雨量波动明显。季节变化表明,冬季的温度上升表现比较显著,春季和秋季次之,夏季温度有所降低;降雨量在夏季和冬季增多较为显著,特别是夏季降雨的增多对年降雨量增加的贡献程度最大,春、秋季都有所减少。
The data of daily temperature and precipitation in 1960-2010 in Huoshan county was collected,and statistical method and linear regression analysis method were employed to analyze the changes of characteristics of temperature and precipitation.The results show that the annual average temperature and the annual total precipitation are characterized by rising trend in that period.The growth rate of temperature is0.177℃/10 a,the growth rate of precipitation is 28.17mm/10 a,and precipitation has experienced evident fluctuation.Seasonal change shows that the winter temperature increases significantly,followed by those of spring and autumn,while summer temperature reduces.Increased rainfall in summer and winter is significant,especially the increase of summer precipitation contributes most to the increase of annual precipitation,while the precipitation in spring and autumn reduces.
