By employing a heat budget analysis appropriate to zonally and time averaged conditions within the atmosphere, it is shown that the net downward heat flux Q at the ocean's surface can be expressed as ...
Numerical Simulation of the Arctic Ocean Circulation
Numerical Simulation Arctic Ocean Circulation
2009/3/7
The circulation of the Arctic Ocean and Greenland Sea is simulated using the 1969 numerical model of Bryan and Cox. The coastline and bottom topography of the region are resolved by a 110 km horizonta...
An Example of Eddy-Induced Ocean Circulation
Eddy-Induced Ocean Circulation Gyre scale local vorticity balances
2009/2/18
Gyre scale and local vorticity balances are examined for a single numerical experiment designed to elucidate the role of eddies in the oceanic general circulation. Due to the complex nature of the flo...
