The large-scale atmospheric circulation redistributes heat, moisture, and atmospheric tracers around the globe, playing a key role in shaping regional climate and climate change. The large-scale circulation is in return shaped by the interactions of large-scale dynamics with the global energy budget and hydrological cycle and with smaller scale processes such as mesoscale motions and cloud processes. Disentangling the many processes that shape the large-scale circulation and its response to climate change requires a combination of conceptual understanding, hierarchical modeling, and observations. 

We welcome observational, modeling, and theoretical studies on the dynamics of large-scale atmospheric circulations such as jet streams, storm tracks (including blocking and atmospheric rivers), stationary waves, monsoons, and tropical overturning circulations. Contributions on the response of these circulations to climate change are particularly encouraged.
