The Scripps Coupled Ocean-Atmosphere Regional (SCOAR) model, with applications in the eastern Pacific sector

Journal of Climate,20, 381-402.

Abstract. A regional coupled ocean-atmosphere model is introduced. It is designed to admit the air-sea feedbacks arising in the presence of an oceanic mesoscale eddy field. It consists of the Regional Ocean Modeling System (ROMS) and the Regional Spectral Model (RSM). Large-scale forcing is provided by NCEP/DOE reanalysis fields, which have physics consistent with the RSM. Coupling allows the sea surface temperature (SST) to influence the stability of the atmospheric boundary layer and, hence, the surface wind stress and heat flux fields. The system is denominated the Scripps Coupled Ocean- Atmosphere Regional (SCOAR) model.
The model is tested in three scenarios in the eastern Pacific Ocean sector: tropical instability waves of the eastern tropical Pacific; mesoscale eddies and fronts of the California Current System; and gap winds of the Central American Coast. Recent observational evidence suggests air-sea interactions involving the oceanic mesoscale in these three regions. Evolving SST fronts are shown to drive an unambiguous response of the atmospheric boundary layer in the coupled model. This results in significant model anomalies of wind stress curl, wind stress divergence, surface heat flux and precipitation that resemble the observations and substantiate the importance of ocean-atmosphere feedbacks involving the oceanic mesoscale.
