On the Use of QuikSCAT Scatterometer Measurements of Surface Winds for Marine Weather Prediction

Creator:: Chelton, Dudley B., Freilich, Michael H., Sienkiewicz, Joseph M., and Von Ahn, Joan M.
Abstract:: The value of Quick Scatterometer (QuikSCAT) measurements of 10-m ocean vector winds for marine weather prediction is investigated from two Northern Hemisphere case studies. The first of these focuses on an intense cyclone with hurricane-force winds that occurred over the extratropical western North Pacific on 10 January 2005. The second...

A Global Climatology of Surface Wind and Wind Stress Fields from Eight Years of QuikSCAT Scatterometer Data

Creator:: Risien, Craig M. and Chelton, Dudley B.
Abstract:: Global seasonal cycles of the wind and wind stress fields estimated from the 8-yr record (September 1999–August 2007) of wind measurements by the NASA Quick Scatterometer (QuikSCAT) are presented. While this atlas, referred to here as the Scatterometer Climatology of Ocean Winds (SCOW), consists of 12 variables, the focus here...

The Midlatitude Resolution Capability of Sea Level Fields Constructed from Single and Multiple Satellite Altimeter Datasets

Creator:: Greenslade, Diana J. M., Chelton, Dudley B., and Schlax, Michael G.
Abstract:: A formalism recently developed for determining the effects of sampling errors on objectively smoothed fields constructed from an irregularly sampled dataset is applied to investigate the relative merits of single and multiple satellite altimeter missions. For small smoothing parameters, the expected squared error of smoothed fields of sea surface height...

Eddy properties in the California Current System

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...

Sampling Errors in Wind Fields Constructed from Single and Tandem Scatterometer Datasets

Creator:: Schlax, Michael G., Chelton, Dudley B., and Freilich, Michael H.
Abstract:: Sampling patterns and sampling errors from various scatterometer datasets are examined. Four single and two tandem scatterometer mission scenarios are considered. The single scatterometer missions are ERS (with a single, narrow swath), NSCAT and ASCAT (dual swaths), and QuikSCAT (a single, broad swath obtained from the SeaWinds instrument). The two...

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...

Air–Sea Heat Exchange along the Northern Sea Surface Temperature Front in the Eastern Tropical Pacific

Creator:: Thum, Nicolai, Esbensen, Steven K., Chelton, Dudley B., and McPhaden, Michael J.
Abstract:: The atmospheric response to the oceanic forcing in the eastern Pacific along the northern equatorial sea surface temperature (SST) front is investigated in terms of sensible and latent heat flux during the 6-month period from 28 July 1999 to 27 January 2000 and the 7-month period from 28 June 2000...

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.

Creator:: Chelton, Dudley B., Esbensen, Steven K., Schlax, Michael G., Thum, Nicolai, Freilich, Michael H., Wentz, Frank J., Gentemann, Chelle L., McPhaden, Michael J., and Schopf, Paul S.
Abstract:: Satellite measurements of surface wind stress from the QuikSCAT scatterometer and sea surface temperature (SST) from the Tropical Rainfall Measuring Mission Microwave Imager are analyzed for the three-month period 21 July–20 October 1999 to investigate ocean–atmosphere coupling in the eastern tropical Pacific.

The Effects of Wind Forcing and Background Mean Currents on the Latitudinal Structure of Equatorial Rossby Waves

Creator:: Perez, Renellys C., Chelton, Dudley B., and Miller, Robert N.
Abstract:: The latitudinal structure of annual equatorial Rossby waves in the tropical Pacific Ocean based on sea surface height (SSH) and thermocline depth observations is equatorially asymmetric, which differs from the structure of the linear waves of classical theory that are often presumed to dominate the variability. The nature of this...
