Arctic sea ice is declining at an increasing rate with potentially important repercussions. To understand better the atmospheric changes that may have occurred in response to Arctic sea ice loss, this study presents results from atmospheric general circulation model (AGCM) experiments in which the only time-varying forcings prescribedwere observed variations inArctic sea ice and accompanying ch...

Abstract Northern Hemisphere (NH) climate has experienced various coherent wintertime multidecadal trends in stratosphere, troposphere, ocean, and cryosphere. However, the overall mechanistic framework linking these is not well established. Here we show, using long-term transient forced coupled simulation, that large parts of NH-multidecadal changes can be understood within a damped stratospher...
