On the necessity of creating a series of oceanographic climatic research atlases (SOCRAT)

Resumo

In this paper, an integration method is proposed for a system of ocean dynamics equations (3DPEM) for creating a series of atlases with the joint title SOCRAT so that circulation in lower ocean layers can be adjusted to circulation in upper layers, avoiding smoothing of the intensity in upper layers caused by long integration or poor resolution. Specific simulations are presented, which were carried out by the author with a group of colleagues. These results conserve the realistic features of circulation thanks to the short integration period and high resolution. It is shown that due to long integration and/or simulation with rough resolution, simulations lose the main feature of ocean dynamics: intense alongshore currents; as a result, a nonexistant stable physical state uncharacteristic of an ocean is imposed.
