Research Advance of Surface Temperature Change over Tibetan Plateau

Tibetan Plateau is an important part of the global climate system,its dynamic effect,heat effect and climatic factors have profound impacts on the global climate system change.This article reviewed and summarized the researches on different interdecadal changes of plateau surface air temperature,and its relationship with temperature change in the same period of other regions in China.Analysis shows that the plateau temperature changed with apparent interdecadal characteristics.The plateau temperature over the past century could be divided into two cold periods and two warm periods,and there were three abrupt changes.The time of three temperature's abrupt change over Tibetan Plateau was ahead of other regions in China.The warming rate of daily minimum temperature was 1 to 3 times of the daily maximum temperature in most regions of the plateau,and the daily temperature range was becoming smaller,and temperature increase in winter was most obvious.Because of vast and varied topography,there were regional differences in temperature change over Tibetan Plateau.Existing research results indicated that plateau temperature change first appeared in the south-east region and higher elevation region.
