극지역 온도 상승 및 강수 증가에 대한 스톰의 역할

Abstract

The climate responses to the anthropogenic greenhouse gas forcing are spatially non-uniform and the underlying dynamics of these responses remain unclear. We find that poleward shift of jet streams and associated weather storm feedback play a critical role in enhancing polar warming and moistening. Storm feedback in this case tends to follow a simple rule: providing anomalous heat and moisture fluxes to the left of anomalous jet stream flow. This rule can be used for understanding dynamical climate responses to the anthropogenic forcing.
