Comparisons of Daily Sea Surface Temperature Analyses for 2007–08

Creator:: Reynolds, Richard W. and Chelton, Dudley B.
Abstract:: Six different SST analyses are compared with each other and with buoy data for the period 2007–08. All analyses used different combinations of satellite data [for example, infrared Advanced Very High Resolution Radiometer (AVHRR) and microwave Advanced Microwave Scanning Radiometer (AMSR) instruments] with different algorithms, spatial resolution, etc. The analyses...

Objective Determination of Feature Resolution in Two Sea Surface Temperature Analyses

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...

Coupling between Sea Surface Temperature and Low-Level Winds in Mesoscale Numerical Models

Creator:: Song, Qingtao, Chelton, Dudley B., Esbensen, Steven K., Thum, Nicolai, and O'Neill, Larry W.
Abstract:: This study evaluates the impacts of sea surface temperature (SST) specification and grid resolution on numerical simulations of air–sea coupling near oceanic fronts through analyses of surface winds from the European Centre for Medium-Range Weather Forecasts (ECMWF) model. The 9 May 2001 change of the boundary condition from the Reynolds...

Observations of SST-Induced Perturbations of the Wind Stress Field over the Southern Ocean on Seasonal Timescales

Creator:: O'Neill, Larry W., Chelton, Dudley B., and Esbensen, Steven K.
Abstract:: The surface wind stress response to sea surface temperature (SST) over the latitude range 30°–60°S in the Southern Ocean is described from the National Aeronautics and Space Administration's QuikSCAT scatterometer observations of wind stress and Reynolds analyses of SST during the 2-yr period August 1999 to July 2001. While ocean–atmosphere...

High-Resolution Satellite Measurements of the Atmospheric Boundary Layer Response to SST Variations along the Agulhas Return Current

Creator:: O'Neill, Larry W., Chelton, Dudley B., Esbensen, Steven K., and Wentz, Frank J.
Abstract:: The marine atmospheric boundary layer (MABL) response to sea surface temperature (SST) perturbations with wavelengths shorter than 30° longitude by 10° latitude along the Agulhas Return Current (ARC) is described from the first year of SST and cloud liquid water (CLW) measurements from the Advanced Microwave Scanning Radiometer (AMSR) on...

The Impact of SST Specification on ECMWF Surface Wind Stress Fields in the Eastern Tropical Pacific

Creator:: Chelton, Dudley B.
Abstract:: The impact of SST specification on low-level winds in the operational ECMWF numerical weather prediction model is investigated in the eastern tropical Pacific from comparisons of ECMWF wind stress fields with QuikSCAT satellite scatterometer observations of wind stress during the August–December cold seasons of 2000 and 2001. These two time...

Covariability of Surface Wind and Stress Responses to Sea Surface Temperature Fronts

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)...

The Effects of SST-Induced Surface Wind Speed and Direction Gradients on Midlatitude Surface Vorticity and Divergence

Creator:: O'Neill, Larry W., Chelton, Dudley B., and Esbensen, Steven K.
Abstract:: The effects of surface wind speed and direction gradients on midlatitude surface vorticity and divergence fields associated with mesoscale sea surface temperature (SST) variability having spatial scales of 100–1000 km are investigated using vector wind observations from the SeaWinds scatterometer on the Quick Scatterometer (QuikSCAT) satellite and SST from the...

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...

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...
