Abstract:
The research on the response of plateau snow cover to solar activity is a relatively new field, and there are few related researches about this topic internationally. The snow cover over the Tibetan Plateau in winter and spring has an important influence on the East Asian monsoon and precipitation in China. Therefore, it is of great significance to study the influence and amplification of solar activity on the snow cover over the Tibetan Plateau. On the basis of reviewing the previous research results, this paper gives the recent research results, and prospects of the further research work in the future. The results showed that the temporal and spatial distributions of plateau snow cover have significant responses to the solar activity, and the mechanism is that the solar activity could cause the abnormal snow cover over the Tibetan Plateau through the joint action of bottom-up mechanism and top-down mechanism. Solar activity can cause anomalous 0-200 m global sea surface temperature and latent heat flux over the Pacific Ocean, which could change the air-sea interaction, further to affect the precipitation of China and plateau snow, amplifying the influence of solar activity. On the other hand, through affecting stratospheric temperature and circulation, solar activity alters interaction of stratospheric and tropospheric atmosphere and wind field to induce anomalous plateau snow. In this paper, the future research work is prospected, and it is pointed out that the key to simulate the influence of solar activity on plateau snow is that the climate system model should include detailed chemical process in upper atmosphere and air-sea coupling process.
