摘要
为了研究山西东南部地区气温变化特征趋势,笔者利用1971—2011年山西东南部地区16个气象站的气温资料,采用线性倾向估计法、滑动平均法及突变分析法等手段,分析了近40年来山西东南部地区气温变化特征。时间分析结果表明:山西省东南部地区近40年的年平均气温、年平均最高气温、年平均最低气温、年极端最高气温、年极端最低气温均呈上升趋势,其气温倾向率分别为0.27℃/10 a、0.29℃/10 a、0.36℃/10 a、0.18℃/10 a、0.46℃/10 a,且发生突变时间为1989年;空间分析结果表明:山西东南部地区中部及东南部地区的升温幅度高于北部及东北部地区,总体呈上升趋势。
The paper aims to study the characteristics of temperature variation tendency in southeast Shanxi Province. The authors used linear trend estimation method, moving average method and mutation analysis toanalyze the temperature variation characteristics in nearly 40 years in southeast Shanxi Province based on thedata of 1971-2011 from 16 stations. The temporal analysis showed that the annual average temperature, theannual average maximum temperature, the annual average minimum temperature, the annual extrememaximum temperature and the annual extreme minimum temperature were all on the rise, the tendency rate ofthe above temperatures was 0.27℃/10 a, 0.29℃/10 a, 0.36℃/10 a, 0.18℃/10 a and 0.46℃/10 a, respectively,the mutation time was 1989. The spatial analysis showed that the warming range of the central andsoutheastern region was higher than that of the northern and northeastern region, and had an overall risingtendency.
