摘要
以忻州市1961～2010年气温和降水资料为研究对象,分析了忻州市50 a的气候变化情况,得出其发展变化趋势。结果表明:50 a来忻州市气温呈非连续性的增温趋势,上升率为0.1℃/10 a;降水在年代背景增多的情况下呈减少趋势,减少率为4.5 mm/10 a。预计未来10 a,忻州市的气温变化趋势呈非连续性升高趋势,年降水量呈非连续性减少趋势。
Using the temperature and rainfall data in Xinzhou City from 1961 to 2010, the climate change was analyzed. The results indicated that the temperature showed discontinuous increasing, and the increasing rate was 0. 1℃/10 a. The rainfall showed the decreasing tendency, and the decreasing rate was 4. 5 mm/10 a. It was predicted that the annual precipitation would decrease discontinuously, and the temperature would increase discontinuously in the next ten years.
