The Resolution Capability of an Irregularly Sampled Dataset: With Application to Geosat Altimeter Data
Publisher: American Meteorological Society
Abstract: A formalism is presented for determining the wavenumber-frequency transfer function associated with an irregularly sampled multidimensional dataset. This transfer function reveals the filtering characteristics and aliasing ...
Filter Transfer Functions for the Method of Successive Corrections
Publisher: American Meteorological Society
Abstract: The frequency-domain characteristics of the successive corrections method in one dimension are investigated through the calculation of smoother weights and filter transfer functions. The successive corrections algorithm ...
The Accuracies of Smoothed Sea Surface Height Fields Constructed from Tandem Satellite Altimeter Datasets
Publisher: American Meteorological Society
Abstract: A technique previously developed for assessing the effects of sampling errors on sea surface height (SSH) fields constructed from satellite altimeter data is extended to include measurement errors, thus providing estimates ...
The Accuracies of Crossover and Parallel-Track Estimates of Geostrophic Velocity from TOPEX/Poseidon and Jason Altimeter Data
Publisher: American Meteorological Society
Abstract: Mean-squared errors of surface geostrophic velocity estimates from the crossover and parallel-track methods are calculated for altimeters in the Ocean Topography Experiment (TOPEX)/Poseidon and Jason orbits. As part of the ...
Sampling Errors in Wind Fields Constructed from Single and Tandem Scatterometer Datasets
Publisher: American Meteorological Society
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, ...
Summertime Coupling between Sea Surface Temperature and Wind Stress in the California Current System
Publisher: American Meteorological Society
Abstract: Satellite observations of wind stress and sea surface temperature (SST) are analyzed to investigate ocean?atmosphere interaction in the California Current System (CCS). As in regions of strong SST fronts elsewhere in the ...
The Midlatitude Resolution Capability of Sea Level Fields Constructed from Single and Multiple Satellite Altimeter Datasets
Publisher: American Meteorological Society
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 ...
Summertime Influence of SST on Surface Wind Stress off the U.S. West Coast from the U.S. Navy COAMPS Model
Publisher: American Meteorological Society
Abstract: High-resolution mesoscale model sea surface temperature (SST) analyses and surface wind stress forecasts off the U.S. West Coast are analyzed on monthly time scales for robust signatures of air?sea interaction as the surface ...
Satellite Observations of Mesoscale Eddy-Induced Ekman Pumping
Publisher: American Meteorological Society
Abstract: hree 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, ...
Geographical Variability of the First Baroclinic Rossby Radius of Deformation
Publisher: American Meteorological Society
Abstract: Global 1° ? 1° climatologies of the first baroclinic gravity-wave phase speed c1 and the Rossby radius of deformation ?1 are computed from climatological average temperature and salinity profiles. These new atlases are ...
