On the Generation of Mesoscale Eddies and their Contribution to the Oceanic General Circulation. I. A Preliminary Numerical Experiment
Mesoscale Eddies Oceanic General Circulation Preliminary Numerical Experiment
2009/3/24
Numerical experiments on the wind-driven ocean circulation in a closed basin show that mesoscale eddies can appear spontaneously during the integration of the equations of motion for a baroclinic ocea...
The spindown of an ocean is investigated, using a two-layer numerical model. At the initial instant, a pool of warm water the size of the Coral Sea occupies the subtropical portion of the top layer; t...
Pressure fluctuations on the deep seafloor at frequencies below inertial and tidal have been measured. Between 0.1 and 1 cycle per day the variance is about 2 mb2, spectra diminish with increasing fre...
