Extratropical air-sea interactions and extreme events
Session ID#: 85125
Session Description:
Many recent studies have indicated that impacts of the extratropical ocean to the atmosphere occur through sea surface temperature (SST) distribution associated with strong ocean currents and/or eddies. The atmospheric responses are found on various spatiotemporal scales from large-scale atmospheric circulation anomalies, developments of tropical and extratropical cyclones and severe rain-/snow-fall through enhanced heat and moisture supply from the warm ocean. Mechanisms for those impacts, however, are still not fully understood. This session invites contributions on all aspects of extratropical air-sea interactions and related ocean and atmosphere variability and its predictability through observational theoretical and modeling studies.
