Quasi-Geostrophic Topographically Generated Mean Flow over the Continental Margin

Creator:: Samelson, Roger M. and Allen, J. S.
Abstract:: Observations of oppositely directed, monthly mean alongshore currents and wind stress over the continental margin off the Pacific coast of North America motivate the theoretical examination of mean flow generation by topographic lee-wave drag. We formulate a barotropic model for wind-forced shelf-slope flow over variable topography. Our central objective is...

DewarCEOASVentilatedPoolModel.pdf

Creator:: Dewar, W. K., Samelson, Roger M., and Vallis, G. K.
Abstract:: An analytical model of subtropical mode water is presented, based on ventilated thermocline theory and on numerical solutions of a planetary geostrophic basin model. In ventilated thermocline theory, the western pool is a region bounded on the east by subsurface streamlines that outcrop at the western edge of the interior,...

Shafer, Tandon, Amit, Taylor, John R., Terray, Eugene A., Thomas, Leif N., and Ledwell, James R.
Abstract:: Lateral stirring is a basic oceanographic phenomenon affecting the distribution of physical, chemical, and biological fields. Eddy stirring at scales on the order of 100 km (the mesoscale) is fairly well understood and explicitly represented in modern eddy-resolving numerical models of global ocean circulation. The same cannot be said for...

Modeled ocean circulation in Nares Strait and its dependence on landfast-ice cover

Creator:: Shroyer, Emily L., Samelson, Roger M., Padman, Laurie, and Münchow, Andreas
Abstract:: Two simplified ocean simulations are used to study circulation and transport within Nares Strait. The simulations are similar, except that one included a coupled sea ice model that effectively established a landfast ice cover throughout the simulation year. Comparison between the ocean-only and ocean-ice simulations reveals a systematic change in...

Satellite Observations of Mesoscale Eddy-Induced Ekman Pumping

Creator:: Gaube, Peter, Chelton, Dudley B., Samelson, Roger M., Schlax, Michael G., and O'Neill, Larry W.
Abstract:: Three mechanisms for self-induced Ekman pumping in the interiors of mesoscale ocean eddies are investigated. The first arises from the surface stress that occurs because of differences between surface wind and ocean velocities, resulting in Ekman upwelling and downwelling in the cores of anticyclones and cyclones, respectively. The second mechanism...

Modeling the Atmospheric Boundary Layer Wind Response to Mesoscale Sea Surface Temperature Perturbations

Creator:: Perlin, Natalie, de Szoeke, Simon P., Chelton, Dudley B., Samelson, Roger M., Skyllingstad, Eric D., and O'Neill, Larry W.
Abstract:: The wind speed response to mesoscale SST variability is investigated over the Agulhas Return Current region of the Southern Ocean using the Weather Research and Forecasting (WRF) Model and the U.S. Navy Coupled Ocean–Atmosphere Mesoscale Prediction System (COAMPS) atmospheric model. The SST-induced wind response is assessed from eight simulations with...

Coastal Atmospheric Circulation around an Idealized Cape during Wind-Driven Upwelling Studied from a Coupled Ocean–Atmosphere Model

Creator:: Perlin, Natalie, Skyllingstad, Eric D., and Samelson, Roger M.
Abstract:: The study analyzes atmospheric circulation around an idealized coastal cape during summertime upwelling-favorable wind conditions simulated by a mesoscale coupled ocean–atmosphere model. The domain resembles an eastern ocean boundary with a single cape protruding into the ocean in the center of a coastline. The model predicts the formation of an...

Dynamical Analysis of the Boundary Layer and Surface Wind Responses to Mesoscale SST Perturbations

Creator:: O'Neill, Larry W., Esbensen, Steven K., Thum, Nicolai, Samelson, Roger M., and Chelton, Dudley B.
Abstract:: The dynamical response of the marine atmospheric boundary layer (MABL) to mesoscale sea surface temperature (SST) perturbations is investigated over the Agulhas Return Current during winter from a 1-month, high-resolution, three-dimensional simulation using the Weather Research and Forecasting (WRF) mesoscale model. A steady lower boundary condition for July 2002 is...
