Solar influence through the stratospheric dynamical processes is clarified by combination of the observational and chemical-climate model studies. It is shown that the stratospheric circulation change can persist longer in the troposphere through interaction with the oceans, creating regional differences. During the period of high solar activity, stratospheric cooling effect due to the increased greenhouse gases propagates more easily to the troposphere and creates North Atlantic Oscillation-like pattern in the sea-level pressure.
