On the correlation of the mesopause region wind field, the North Atlantic oscillation and the Central Europe winter temperatures

The stratospheric and mesospheric wind field in winter is dominated by the stratospheric polar vortex, which reaches out up into the mesopause region and leads to strong westerlies there in winter. On the other hand, the tropospheric mean winter wind field is also connected with the polar vortex whi...
