Abstract:
This paper briefly reviews the scientific investigation and research progress of the earth air interaction in the Tibetan Plateau (TP) at home and abroad, and summarizes in detail the characteristics of the earth air water heat balance and exchange over the Tibetan Plateau in recent years, as well as its influence on the plateau vortex and the East Asian monsoon.The surface water-energy exchange over the TP can change the thermal process of the TP through changing the boundary layer.Meanwhile, it also influence the plateau vortex of the TP and cause the release of precipitation non-adiabatic heating, resulting in the thermal process of the TP and even the anomalous of thermal difference between East Asia and Pacific, and finally influencing the East Asian summer monsoon.It is found that cold air events, soil moisture and surface latent heat have important effects on the boundary layer thickness.The influence of soil temperature and humidity on the low-value system is different.There is a significant positive correlation between the frequency of TP vortex and ground temperature, but there is no significant correlation between soil moisture and TP vortex.There is also a significant positive correlation between the TP thermal condition and the TP vortex frequency.According to the analysis of precipitation in the low value system over the TP, the vorticity precipitation over the TP increased year by year and fluctuated sharply with multi-peak and multi-valley changes.The summer precipitation in the monsoon margin has a significant positive relationship with the heating in the western TP, but not with the heating in the eastern TP.The area variation of the northern margin of the summer.The results further deepen the understanding of the climatic effects of the TP.
