TL;DR: In this paper, a review of the advances in our understanding of extratropical atmosphere-ocean interaction over the past decade and a half is examined, focusing on the atmospheric response to sea surface temperature anomalies.

TL;DR: In this paper, the causes of hemispherically symmetric variability in the recent observational record were examined using the National Centers for Environmental Prediction-National Center for Atmospheric Research reanalysis dataset and numerical models.

TL;DR: In this paper, a torque is applied to the stratosphere of an idealized general circulation model, and, under some circumstances, a robust tropospheric response is observed, while initiated by stratospheric forcing, are maintained locally by interactions with transient eddies.

TL;DR: In this article, a baroclinic mechanism for the positive eddy feedback on the zonal index is proposed, which explains observed and modeled features of zonal indices variations: the frequency and drag dependence of the eddies feedback, the bandedness in latitude of the zonally averaged zonal wind variations, and the tendency for anomalies in the Zonal wind to drift poleward over time.

TL;DR: In this paper, the atmospheric response to a midlatitude SST anomaly in the North Pacific and its dependence on background flow are examined in a GCM and experiments are conducted using the same warm SST anomalies but two different model states: perpetual January and perpetual February.
