Eddy–Mean Flow Interaction in Zonal Oceanic Jet Flow along Zonal Ridge Topography

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...

Geographical Variability of the First Baroclinic Rossby Radius of Deformation

Creator:

Chelton, Dudley B., deSzoeke, Roland A., Schlax, Michael G., El Naggar, Karim, and Siwertz, Nicolas

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...

The sea state bias in altimeter estimates of sea level from collinear analysis of TOPEX data

Creator:

Chelton, Dudley B.

Abstract:

The wind speed and significant wave height (H1/3) dependencies of the sea state is in altimeter estimates of sea level, expressed in the form ∆hSSB=bH1/3, are examined from least squares analysis of 21 cycles of collinear TOPEX data. The bias coefficient b is found to increase in magnitude with increasing...
