The nao troposphere–stratosphere connection
WebJan 28, 2024 · Here, we show that existence of a transition during the course of the SSW life cycle can be attributable to the condition of North Atlantic Oscillation (NAO) preceding before onset: Positive NAO favors SSW of displacement type with no transition while negative NAO favors the displacement–split type.

Atmospheric rivers and cyclones are synoptic atmospheric phenomena characterized by the strong impact onto the mid- and high latitude costal zones.
WebA simple theoretical model predicts that this is associated with about 300-m elevation of the Arctic tropopause, as is observed, and a 5-hPa lowering of the surface pressure at the North Pole. The effects of the spinup of the tropospheric column may project on the NAO pattern so that the stratosphere acts as an integrator of the NAO index. 1.
