[Climate Change] The Surface Sensible Heat over the Tibetan Plateau Change Under the Recent Global Warming Hiatus

In the late 1950s, Ye Duzheng demonstrated that the Tibetan Plateau (TP)is a heat source for the atmosphere in summer ,meanwhile he argued for the first time that the TP is a cold source in winter.He investigated the heat source over TP in summer and its influence on the atmospheric circulation in East Asia,thus reclaiming the study of the thermal effects of the megarelief and carving out TP meteorology.On the occasion of the centenary of the birth of Mr. Ye Duzheng, using the method of calculating the sensible heat (SH)proposed by Mr. Ye in 1979, Huang Gang team, State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics, Institute of Atmospheric Physics, Chinese Academy of Sciences, investigate the evolution of SH over the central and eastern Tibetan Plateau (CE-TP) under the recent global warming hiatus. This paper is dedicated to the great founder of TP meteorology, Ye Duzheng, and its first auther is a doctoral student of Professor Huang Gang ,named Zhu Lihua.


The results reveal that the SH over the CE-TP presents a recovery since the slowdown of the global warming. The restored surface wind speed together with increased difference in ground-air temperature contribute to the recovery in SH. During the global warming hiatus, the persistent weakening wind speed is alleviated due to the variation of the meridional temperature gradient. Meanwhile, at nighttime, the increased total cloud cover reduces the surface effective radiation via a strengthening of atmospheric counter radiation and subsequently brings about a clear upward trend in ground surface temperature and the difference in ground-air temperature. The results will be published in special issue for Mr. Ye of Advances in Atmospheic Sciences ,and it has been pre-published online.
