平流层-对流层相互作用研究进展：等熵位涡理论的应用及青藏高原影响
Progress in research of stratosphere-tropo- sphere interactions:Application of isentropic potential vorticity dynamics and the effects of the Tibetan Plateau
摘要
Abstract
This paper reviews recent progress in understanding isentropic potential vorticity (PV)dynamics during interactions between the stratosphere and troposphere,including the spatial and temporal propagation of circulation anomalies associated with the winter polar vortex oscillation and the mechanisms of stratosphere-troposphere coupling in the global mass circulation framework.The origins and mechanisms of interannual variability in the stratospheric circulation are also reviewed.Particular attention is paid to the role of the Tibetan Plateau as a PV source (via its thermal forcing)in the global and East Asian atmos-pheric circulation.Diagnosis of meridional isentropic PV advection over the Tibetan Plateau and East Asia indicates that the distributions of potential temperature and PV over the east flank of the Tibetan Plateau and East Asia favor a downward and southward isentropic transport of high PV from the stratosphere to the troposphere.This transport manifests the possible in-fluence of the Tibetan Plateau on the dynamic coupling between the stratosphere and troposphere during summer,and may pro-vide a new framework for understanding the climatic effects of the Tibetan Plateau.关键词
