Abstract

A coupled atmosphere-ocean wave system for understanding air-sea fluxes W. ~errie' & Y. zhang2 'ocean Sciences Div., Maritimes Region, Fisheries & Oceans Canada Bedford Institute of Oceanography, Canada 2~ept. of Atmospheric Sciences, Nanjing University, PR China Abstract Our model for atmosphere-ocean wave coupled dynamics consists of the NCAR RegCM2 climate model and the WAM ocean wave model. Our domain of implementation is the North Atlantic. Coupling of atmospheric and surface ocean dynamics is achieved by the HEXOS sea-state dependent roughness. No explicit sea-state dependent thermal mechanism such as sea spray is considered. Our time-scales for simulations range from synoptic to seasonal. Results are compared with data collected during LSDCE (Labrador Sea Deep Convection Experiment). 1 Introduction The study of climate dynamics and climate change requires an understanding of the exchanges of momentum, heat and water vapor at the air-sea interface. This is important for simulations and
