We present a simple model for the surface of the ocean, suitable for the modeling and rendering of most common waves where the disturbing force is from the wind and the restoring force from gravity.It is based on the Gerstner, or Rankine, model where particles of water describe circular or elliptical stationary orbits.

A backscattering model for ocean surface
IEEE Transactions on Geoscience and Remote Sensing, 1992A surface scattering model based on an approximate solution of the integral equations for the surface tangential fields has been developed for non-Gaussian distributed, finitely conducting surfaces. It consists of two parts. One part is proportional to the surface roughness spectrum, and the other to the surface bispectrum.

Bistatic model of ocean scattering
IEEE Transactions on Antennas and Propagation, 1998An analytical closed-form model is derived for the average power echo received by a bistatic altimeter from an oceanic surface at a frequency high enough for the Kirchhoff scattering mechanism to be dominant over the Bragg resonance one. The asymmetric behavior of the sea waves is taken into account, modeling the surface height as a non-Gaussian ...

Models of the Ocean: Which Ocean?
2006Physics actually represented in an ocean model depend on each model’s resolution and its parameterization of subgridscale effects. This chapter is a review of parameterizations used in ocean models, focussing on operational ocean forecasting systems for the North Atlantic and Mediterranean Sea. This review is limited to z-coordinate models.

Ocean color is determined by spectral variations in reflectance at the sea surface. In the analytic model presented here, reflectance at the sea surface is estimated with the quasi-single-scattering approximation that ignores transspectral processes. The analytic solutions we obtained are valid for a vertically homogeneous water column.

Coupled atmosphere-ocean models are at the core of numerical climate models. There is an extraordinarily broad class of coupled atmosphere-ocean models ranging from sets of equations that can be solved analytically to highly detailed representations of Nature requiring the most advanced computers for execution.

Modelling of Geochemical Tracers in the Ocean
1990The basic mechanisms of marine biology and chemistry which influence the atmospheric concentration of carbon dioxide are embedded in the three-dimensional current field of an OGCM. The modelled tracers are phosphate, alkalinity, oxygen, dissolved inorganic carbon, particulate organic carbon, and calcite, the latter three in three isotopes.

Modeling Equatorial Ocean Circulation
Annual Review of Fluid Mechanics, 1985Double objectif de l'article: presenter, aussi succinctement que possible, les principes de la dynamique equatoriale, et passer en revue les recents developpements en la matiere. Les differents chapitres traitent successivement: des modeles suivant leur sophistication dynamique; des solutions non forcees, des solutions forcees par des vents qui s ...

Oceans and ocean models as seen by current meters
Journal of Geophysical Research, 2011[1] From a collection at 18,588 current meter locations spanning 12,825 observation years, we examine ocean circulation in terms of topostrophy. We affirm previous indications of strongly positive topostrophy toward higher latitudes, and we consider variation with depth. We explore use of the current meter data set for evaluating models skills. This is
