A41A:
Air-Sea Exchange Processes in Western Boundary Current Systems and Marginal Seas: Their Local and Remote Climatic Implications II


Session ID#: 11288

Session Description:
This session focuses on intense surface fluxes of heat, moisture and momentum within western boundary current systems and adjacent marginal seas, known as climatic “hot spots”. Particular emphasis is placed on oceanic and atmospheric processes over a wide range of spatial and temporal scales that contribute to huge amounts of heat and moisture supplied from the ocean to the atmosphere and wind forcing onto the ocean as well. Contributions for oral and poster presentations based on diagnostic, modeling (either realistic or idealized) and theoretical studies are invited on a range of topics including, but not limited to, the processes affecting spatial and temporal variations in surface fluxes around the oceanic fronts/jets and meso-scale eddies, their local and large-scale influence on air temperature and wind distributions, organization of cloud and precipitation systems, cyclone development, the formation of storm tracks and jet streams, and their feedbacks/influences on ocean currents/jets and mode water formation, and their interactions with marine ecosystems. Observational (both in situ and remote sensing) analyses to characterize these processes and to evaluate their representations in atmosphere/ocean models and reanalyses are encouraged. Contributions are also invited on surface chemical fluxes and related processes.
