Abstract:

Trends of atmospheric temperature during 1980-2007 over the Tibetan Plateau were evaluated using the ERA-Interim and MERRA-2 reanalysis data sets. Analyses of different time scales from annual to seasonal and monthly show that remarkable reversal trends of atmospheric temperature after 2008: temperatures at the lower stratosphere (150-50 hPa) are increasing with rates of 1.0-2.7℃/10a, while in the upper troposphere (300-175 hPa), temperatures are decreasing with rates of -3.1- -1.0℃/10a. Trends of atmospheric temperature in spring after 2008 over the Tibetan Plateau are reversal with those of 1980-2007. Analysis of total ozone trends over the Tibetan Plateau during 1980-2017 were carried out and results show significant increasing trends of monthly total ozone from end of winter to spring, especially in May with the highest increasing rate of 13.7 DU/10a. Analysis results show that variations of atmospheric temperature are closely linked with variation of total ozone, and the reversal trends of atmospheric temperature in spring maybe the results of total ozone recovery after 2008 over the Tibetan Plateau.
