The Causes of the Interannual Variation of Snow Cover over the Tibetan Plateau

WEI Zhi-gang~1,HUANG Rong-hui~2,CHEN Wen~2 (1. Cold and Arid Regions Environmental and Engineering Research Institute, Chinese Academy of Sciences, Lanzhou Gansu 730000, China;2. Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, China)  
Analyzing the station snow, air temperature, precipitation and reanalyzed NECP/NCAR data demonstrates: The winter-spring snow in Tibetan Plateau has obvious negative correlation to the air temperature but positive correlation to the precipitation in the pre-winter (November and December) in Plateau according to its interannual variation. In the pre-winter of the rich (poor) winter-spring snow years in the plateau, the subtropical anticyclone is strong (weak), the polar vortex over Europe and Asia is strong (weak), and the trough over Europe is deep (shallow), the ridge over Ural is strong (weak), the trough line over East Asia inclines much (little) from northeast to southwest. Therefore, the warm and wet air from ocean flows easily (hard) to the plateau and the cold air from Siberia flows easily (hard) to the plateau, and the snowfall falls much (little) and the snow exists long (short).
