| 本文以运城市1971—2010年间气温、降水和日照时数等资料为基础，运用线性回归分析法分析了运城市近40年来气候变化特征。研究表明：近40
年来，运城市年平均气温呈波动上升趋势，冬、春季升温明显，夏、秋季升温幅度较小；年降水量则呈缓慢下降趋势，除冬季降水略呈增长趋势外，其它季节均呈下降趋势，其中春秋
季下降幅度较大；运城市春季日照时数略呈上升趋势，冬、夏和秋季均处于下降趋势，其中夏秋季下降趋势明显，冬季较为平缓。 |
| 英文摘要: |
| Based on the data of temperature, precipitation and sunshine hours in Yuncheng during 1971—2010 and using the linear regression analysis, the climate change of Yuncheng in recent 40 years was studied. The results showed that the annual mean temperature had a fluctuating upward trend. The temperature increased significantly in winter and spring and slowly in summer and autumn. The annual precipitation tended to decrease slowly overall. But precipitation in winter had a slight increase tendency. Precipitation in the other seasons decreased, especially in spring and autumn. It was found that the annual sunshine had a significant increase tendency in spring and a decrease tendency in the other 3 seasons. The reduction rate of sunshine in summer and autumn is more obvious than that in winter. |
