Roger M. Samelson - Coastal Ocean and Atmosphere

The physics of the coastal ocean and atmosphere, and the processes that couple them, are of particular interest to me and to many of my colleagues at COAS. My recent research in the area has focused on air-sea interaction and the coupling between wind stress and sea surface temperature. For example, Perlin et al. (JPO, 2007) find that in simulations of coastal upwelling using a coupled ocean-atmosphere model, wind stress over the inner shelf may be reduced by half by the interaction of the oceanic and atmospheric surface boundary layers.
