The coupled characteristics of the physical process between sea rnice of two poles and Tibetan land surface

摘要

In order to discuss the characteristics of sea ice change of strong signal area rnon Antarctic and Arctic and the correlation between the thermal state on the land rnsurface of Tibetan Plateau and the atmosphere circulation of North Hemisphere or the rnclimate changes in China, and to study the feedback mechanism among “three-pole” rnfactors, the earlier stage “three-pole” strong signal characteristics by using statistic rnmethods such as teleconnection,which affect the regional climate changes in China and rnEast Asia. The cross-correlation feature and coupling effect between ice caps of North rnand South pole and water-thermal state on Tibetan Plateau surface are discussed as rnwell. The contribution of three-pole's earlier stage factors to China's summer climate rnchange and the influence of its dynamic structure are compared here. The formation rnmechanisms of global climate change and regional climate change of China are rninvestigated from the aspect of qualitative correlation mode of global sea-land-air-ice.
