There are strong indications that seasonal weather forecasts can be improved by including the middle atmosphere. Also, the middle atmosphere structure and dynamics cannot be described without taking into account the forcing from below. We focus on the interdependence of the different atmospheric layers and the mechanism coupling them together, in particular in respect to potential solar forcing.
