摘要
利用隰县、临汾、运城3个地面气象站1961年-2010年的气温资料,分析了晋南地区近50年来气温变化趋势。结果表明,晋南地区1961~2010年间年均气温呈上升趋势,增温速率为0.35℃/10a,高于山西省和全国气温平均增长率,并且年均气温的上升主要源于冬春季节的快速升温。同时,该区60年代和70年代为相对寒冷期,而90年代和本世纪前十年为相对温暖期,特别是本世纪前十年增温趋势十分明显。
Base on the data of air temperature and precipitation from 3 weather stations of Xi county, Linfen city and Yuncheng city during 1961-2010, the changes of air temperature and precipitation was analyzed in southern of Shanxi province in recent 50 years. The results showed that mean annual temperature increased significantly, the warming rate is 0.35~（2 per 10 years, which is higher than that in Shanxi province and countrywide, and the reason of increase of mean annual temperature mostly due to warming up in winter and spring. It is relative cold period in 60s and 70s of last century during recent 50 years, and it＇ s relative warm period in 90s and in the first decade of the 21st century, and the first decade of the 21st century is the most remarkable stage of warming trend.
