摘要
利用青岛市崂山区1965~2015年的气象观测资料,采用线性倾向估计、累计距平、Mann-Kendall突变检验等方法,研究了崂山区51年来气温、降水、日照、相对湿度的年、季变化特征,结果表明:在全球气候变暖的大背景下,崂山区年、季平均气温显著升高但是降温幅度均较小,降水量下降趋势不显著,年际差别较大,日照时数显著减少,平均相对湿度显著降低,总体来看,崂山区1965~1979年前后表现为湿冷型气候,1980年以来尤其是20世纪90年代以后崂山区全年及夏季、秋季表现为暖干型气候,冬季和春季表现为暖湿型气候。
According to the meteorological observation data of Laoshan district in Qingdao city during 1965 - 2015,by using linear trend estimation,cumulative anomaly,and Mann-Kendall mutation testing methods,we studied the annual and seasonal change characteristics of air temperature,relative humidity,precipitation and sunshine duration in Laoshan district in the past 51 years. The results indicated that： under the background of global warming,the annual and seasonal average air temperature in Laoshan district increased significantly, but their dropping scales were relatively small; the precipitation decreased unsignificantly,and its interannual difference was relatively big; the sunshine duration reduced significantly; the average relative humidity decreased significantly. On the whole,the climate in Laoshan district from 1965 to 1979 was wet-cold type; since the year 1980,especially after the 1990 s,the annual,summer and autumn climate in this district was warm-dry type,while the winter and spring climate was warm-wet type.
