| Abstract: | Numerical experiments on the reconstruction of upwelling and downwelling at the eastern boundary of the ocean were carried out in the framework of a multilayer model of the ocean involving the upper mixed layer (UML). The peculiarities of these phenomena when they are formed and attenuated owing to the strong intensification and abatement of the longshore wind have been studied. It is shown that cold waters are always involved from the thermocline to the UML during upwelling. In downwelling, this occurs as a rule. However, during upwelling the abatement of the wind may result in subduction —the inflow of warm waters from the UML to the thermocline.Translated by Mikhail M. Trufanov. |
