The large-scale atmospheric circulation is an essential component of the climate system. Understanding the drivers, variability and the dynamical processes of this circulation is important for improving future projection of global and regional circulation patterns under anthropogenic climate change, and for predicting the associated impacts on extreme weather and climate events.
This session encourages contributions covering various theoretical and practical aspects of the large-scale atmospheric circulation, including but not limited to the following topics:
· The response of the large-scale atmospheric circulation to climate change, including latitudinal shifts of the jet stream and the Hadley cell subtropical edge.
· Changes and trends in storm track intensity and structure in response to climate change, or due to internal variability.
· The representation of the large-scale atmospheric circulation in climate models: inter-model variability, model biases and ways to reduce uncertainty in model projections.
· Novel metrics and analysis methods for studying the large-scale atmospheric circulation, using observational or model data.
· Interactions between the different components of the large-scale circulation, including tropical-extratropical interactions and teleconnection patterns.
· The role of moisture in the large-scale atmospheric circulation.
· Energy transport by the large-scale atmospheric circulation.
· Stratospheric-tropospheric interactions affecting the large-scale circulation.
