Creator:: Chelton, Dudley B. and Kosro, P. Michael, 1951-
Abstract:: CTD observations were made over the continental shelf and upper continental slope from the coast to approximately 60 km off central California between latitudes 34°N and 37.5°N. The measurements were made by Raytheon Service Company as part of the Central California Coastal Circulation Study sponsored by the Minerals Management Service....

Creator:: Reynolds, Richard W., Chelton, Dudley B., Roberts-Jones, Jonah, Martin, Matthew J., Menemenlis, Dimitris, and Merchant, Christopher John
Abstract:: Considerable effort is presently being devoted to producing high-resolution sea surface temperature (SST) analyses with a goal of spatial grid resolutions as low as 1 km. Because grid resolution is not the same as feature resolution, a method is needed to objectively determine the resolution capability and accuracy of SST...

Creator:: Witter, Donna L. and Chelton, Dudley B.
Abstract:: Motivated by satellite altimeter observations of enhanced sea level variability near steep topographic slopes in the Southern Ocean, effects of topography on the spatial distribution of mesoscale eddies and on eddy–mean flow interaction are investigated using a two-layer, wind-forced, quasigeostrophic channel model. The principal topography, a zonal ridge with a...

Abstract:: Global 1° × 1° climatologies of the first baroclinic gravity-wave phase speed c¹ and the Rossby radius of deformation λ1 are computed from climatological average temperature and salinity profiles. These new atlases are compared with previously published 5° × 5° coarse resolution maps of λ₁ for the Northern Hemisphere and...

Creator:: Berstein, R. L. and Chelton, Dudley B.
Abstract:: A series of satellite sea surface temperature (SST) intercomparison workshops were conducted under NASA sponsorship at the Jet Propulsion Laboratory. Three different satellite data sets were compared with each other, with routinely collected ship data, and with climatology for the months of November 1979, December 1981, March 1982, and July...

Creator:: Gaube, Peter, McGillicuddy, Dennis J., Jr., Chelton, Dudley B., Behrenfeld, Michael J., and Strutton, Peter G.
Abstract:: Eddies can influence biogeochemical cycles through a variety of mechanisms, including the excitation of vertical velocities and the horizontal advection of nutrients and ecosystems, both around the eddy periphery by rotational currents and by the trapping of fluid and subsequent transport by the eddy. In this study, we present an...

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...

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...

Creator:: O'Neill, Larry W., Chelton, Dudley B., and Esbensen, Steven K.
Abstract:: The responses of surface wind and wind stress to spatial variations of sea surface temperature (SST) are investigated using satellite observations of the surface wind from the Quick Scatterometer (QuikSCAT) and SST from the Advanced Microwave Scanning Radiometer on the Advanced Microwave Scanning Radiometer for Earth Observing System (EOS) (AMSR-E)...

Creator:: Kurian, Jaison, Colas, Francois, Capet, Xavier, McWilliams, James C., and Chelton, Dudley B.
Abstract:: Eddy detection and tracking algorithms are applied to both satellite altimetry and a high‐resolution (dx = 5 km) climatological model solution of the U.S. West Coast to study the properties of surface and undercurrent eddies in the California Current System. Eddy properties show remarkable similarity in space and time, and...
