Air-sea interaction is an important driving mechanism for numerous weather and climate phenomena, such as extratropical and tropical cyclones, storm tracks, blockings, atmospheric circulation changes, IPV and AMV, etc. Teleconnections between different ocean basins through atmospheric and oceanic bridges on various timescales can magnify certain weather and climate events downstream. To better serve the broader community, a predictive understanding of these interactions and teleconnections ranging from seasonal to decadal timescales would greatly advance our capability of simulating and predicting these processes. It is also essential to find out whether these interactions and teleconnections in mid-latitudes would change under changing climate and how they would be affected by the internal climate mode variability. In this session, we welcome abstracts studying the observed and model simulated mid-latitude air-sea interactions and the inter-basin teleconnections on multiple timescales and how the various external forcings, e.g., solar, volcano, anthropogenic forcing, would modulate these processes.
