The Dynamics of the Large Scale Atmospheric Circulation in Present and Future Climates: Jet Streams, Storm Tracks, Stationary Waves, and Monsoons
Session ID#: 249207
Session Description:
Large-scale atmospheric circulation plays a key role in the global climate system. Understanding the fundamental dynamics of the large-scale circulation is essential for constraining regional climate projections under a changing climate. Furthermore, the dynamics of the atmospheric general circulation intimately interact with the energy and hydrological cycles, exerting profound impacts on extreme weather and climate events. Such interactions in both the tropics and extra-tropics occur on a wide range of spatial and temporal scales, which calls for a combination of conceptual understanding, hierarchical modeling, and observations.We welcome contributions covering theory, idealized and comprehensive modeling, and novel diagnostic frameworks for observations and CMIP model outputs to improve our understanding of large-scale atmospheric circulation and associated extreme weather events and how they may respond to future climate change. Contributions including, but not limited to, the ITCZ, monsoons, jet streams, storm tracks, blocking, stationary waves, and atmospheric rivers are highly encouraged.
