| 摘 要： | 利用石家庄市1951～2005年气温、降水资料,采用变率分析、趋势分析、小波变换和Mann-Kendall检验等方法对石家庄近55年的气候变化特征进行了分析。结果表明:①夏季、秋季气温变率小,冬季气温变化幅度最大;②年气温和四季气温线性上升趋势显著,春季、冬季升温最明显,近55年气候变暖主要是春季和冬季气温升高造成的。年降水量和四季降水量不存在线性变化趋势;③四季气温和年气温变化的周期性不明显,而降水量变化存在周期性;④石家庄四季气温和年气温在20世纪80年代末和90年初发生了明显的气候突变,而四季降水量和年降水量变化没有发生明显的气候突变。

| Abstract: | The characteristics of climate change in Shjjiazhuang are analyzed on the basis of the monthly air temperature and monthly rainfall data of the Shijiazhuang station from 1951 to 2005 by using the deviation analysis,trend analysis,wavelet transform and abrupt change analysis methods.The results show:(1)The temperature variability was mostly notable in winter and was small in summer and autumn.(2)There were obvious linearly increasing trends in the annual temperature and temperatures in four seasons,obviously in spring and winter.The warming in the recent 55 years can be attributed to the spring and winter temperature increase.There was no linear variation trend in annual precipitation and precipitation in four seasons.(3)The periodicities of annual temperature and temperatures in four seasons were not obvious,but there was periodicity in precipitation changes.(4)There were obvious abrupt changes in annual temperature and temperatures in four seasons,but the same changes are not found in annual rainfall and rainfall in each season. |
