PO002:
Air-Sea Exchange Processes in Western Boundary Current Systems and Marginal Seas: Their Local and Remote Climatic Implications


Session ID#: 29700

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”. These hot spots influence the mean state of Earth’s climate and hydrological cycles both locally and globally through coupled ocean-atmospheric interactions at a variety of spatio-temporal scales.

This session seeks contributions characterizing variability in the air-sea exchanges themselves or their influence on atmospheric and oceanic variability.

Presentations are invited based on diagnostic, modeling and theoretical studies on a range of topics including, but not limited to:

1) High-resolution model inter-comparison projects, either coupled or uncoupled.

2) Processes affecting variations in surface fluxes around oceanic fronts, jets, or mesoscale eddies, and their local and remote influences on temperature, wind, and precipitation distributions.

3) Organization of cloud and precipitation systems.

4) Extratropical cyclone development, variability in mid-latitude storm tracks, jet streams, and precipitation distribution, and their feedbacks and influences on ocean temperature, salinity, currents, and mode water formation.

5) Observational (both in situ and remote sensing) analyses which characterize these processes and evaluate their representations in atmosphere/ocean models and reanalyses.
