| Abstract: |
| 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. |
