Abstract: On the basis of the monthly average temperature data(19612008) in Yunnan Province,the change patterns of spatial and temporal distribution of different climate zones in the past 50 years and their response to Global Warming have been analyzed.The results indicate that firstly,in past 50 years,the annual average temperature change trend of six climate zones in Yunnan consistently shows that the temperature is on the rise.The warming trend of Plateau Climate zone is the most significant.A warming abrupt point of Middle Subtropical zone and North Subtropical zone was observed in the 1990s and others in the 1980s.Secondly,there exists an obviously interdecadal change trend in the annual average temperature of the six climate zones in Yunnan.Thirdly,there is positive relationship between climate zone temperatures in Yunnan and global warming.When the global climate is warmer,the annual average temperature of the six climate zones in Yunnan also become warmer; and vic versa.Fourthly,the annual average temperature of the six climate zones of Yunnan are closely related to the extent and intensity of polar vortex in Asian,the extent,intensity and location of the western Pacific subtropical high,as well as the Indian Myanmar trough and height sum on the Tibet Plateau.Further,from 1961 to 2008,the extent and intensity of polar vortex in Asian and the Indian Myanmar trough decreased and the extent and intensity of the western Pacific subtropical high and height sum on the Tibet Plateau intensified.The western Pacific subtropical high shifted more westward.These changes of circulation may cause the significant increase of annual average temperature of the six climate zones in Yunnan.
