While the thermodynamic effects of rising concentrations of greenhouse gases in the atmosphere are largely well understood, theoretical and experimental work on the effect of a warming planet on atmospheric dynamics is relatively scarce. This limits our ability to detect, understand and predict the effect of climate change on atmospheric circulation and weather regimes, which cause extreme events ranging from storms over heavy precipitation to draughts or heat waves. The present project aims to make a contribution to advance that understanding by examining the effect of drag on atmospheric circulation and its representation in weather and climate models.
