Satellite data has been an important database of climate research because of its global coverage. Based on the MSU /AMSU-A temperature data from 1982 to 2016,this paper analyzes the climate trend and its evolution of air temperature on the upper troposphere over the Tibetan Plateau,the ERA-Interim and NCEP-R2 reanalysis datasets are also included for the comparison. Results show that the air temperature on the upper troposphere is gradually warming over the Qinghai-Tibetan Plateau,which is in good agreement with the changes of atmospheric temperature at the corresponding levels of the two reanalysis datasets. Nonlinear trend analysis based on ensemble empirical mode decomposition ( EEMD) reveals that the warming of the upper tropospheric bright temperature over the Tibetan Plateau starts from the central of the Qinghai-Tibetan Plateau,as the time evolved,the warming trend gradually spread to the periphery of the Tibetan Plateau,and eventually lead to the temperature become warmer for the whole study area. For the ERA-Interim data,the evolution of the climate trend for atmospheric temperature at 300 hPa has good similarity with that of the satellite observations,the warming phenomenon is first observed near the Qinghai-Tibetan Plateau and the warming trend gradually expands to surrounding areas. However,there are significantly differences between the trend of observations and that of the NCEP-R2 data, temperature at 300 hPa of the NCEP-R2 has obvious cooling trend in the first 20 years of the research period,the warming phenomenon only exists in the last 10 years.
