Short summary
We found the climatological strong stratospheric westerly circumpolar wind stops increasing temporarily during November, when the upward propagation of large-scale atmospheric waves from the troposphere increases. The propagation of atmospheric waves, which is strongest over Siberia, is related to strengthening of the low pressure. Longitudinally asymmetric forcing by land–sea heating contrasts caused by their different heat capacities might cause the strengthening of the low pressure.
