- Abstract:
-
We use daily temperature climate statistics of the Tibetan Plateau from 1961 to 2010, and used the linear regression equation, Mann-Kendall mutation testing and other methods to study the spatiotemporal trend of the temperature and climate of the plateau. The results show that:(1) the increase rate of the average annual temperature of the plateau is 0.022 8℃, after 1993, annual average temperature value was high, and average temperatures in the southern region was higher, while the annual average temperature was low in the central region, and abrupt change of temperature in Tibetan Plateau occurred in 1996; (2) the average annual temperature presented the significant seasonal variation, and the average annual temperature trend under four seasons was incremental, warming was the biggest in the spring, and the warming was slight in winter; (3) it was concluded that the average annual presented the distribution characteristics of types of South-Center-North and South-North based on EOF analysis on the average annual temperature.
