Abstract

One of the most prominent features of the Arctic polar vortex is its large interannual variability associated with a high frequency of occurrence of sudden stratospheric warmings (SSWs). SSWs appear due to the breaking and dissipation of planetary Rossby waves, propagating from the troposphere into the stratosphere, as a result of interaction with the westerly zonal flow (i.e. the stratospheric polar vortex). In this study, we analyze the dynamics of the Arctic polar vortex under the influence of the anomalous upward wave activity flux in the winter 2012/2013.
