Geostrophic Current and Associated Vertical Motion off Northeastern Taiwan

1991
Abstract The geostrophic velocity changes its direction with increasing depth by thermal wind relationship. The rate of rotation with depth is related to the vertical velocity by Hide's theorem. A method for calculating the three-dimensional absolute velocity by means of Hide's theorem and beta vorticity dynamics is developed.

On the Mixed Stability Program for Quasi-Geostrophic Ocean Currents

Journal of Physical Oceanography, 1974
Abstract A simple, two-layer, quasi-geostrophic model is used to investigate the stability of baroclinic currents confined to a finite length scale L in a basin of considerably larger dimension (4L). The current distributions studied are typical of oceanic boundary currents and of certain oceanic and atmospheric eddies.

Eddy-Current Interactions using a Two-Layer Quasi-Geostrophic Model

1989
Abstract Processes associated with interactions between a mesoscale eddy and an ocean current are examined using a two-layer quasi-geostrophic model. Model configuration is chosen so that the eddy tends to approach the current, and the chance for interactions is enhanced.

The quasi‐geostrophic advective wave in a baroclinic zonal current

Quarterly Journal of the Royal Meteorological Society, 1951
AbstractAn idealised advective wave is studied on the assumption of geostrophic advection of temperature. There is a genuine instability of zonal motion due to this factor and the wave form is similar to thermally asymmetrical depressions and anticyclones.

Satellite-Based Geostrophic Currents for Improved Ocean Angular Momentum Estimates

Ocean angular momentum (OAM), a measure of the rotational motion of the oceanic fluid masses, undergoes alterations as a consequence of changes in both the distribution of ocean mass and the direction and speed of ocean currents. While a number of products provide estimates of these changes, they rely on global ocean current models.Geostrophic currents
