Large-Scale Circulations Induced by
Localized Mixing in the Ocean
Abstract
Vertical mixing in the ocean interior is generally assumed to be small.
In this talk, we will emphasize that small-scale mixing processes can sometimes
induce basin-scale oceanic currents, such as in the case of the so-called
Azores Current and Countercurrents, which span approximately 3000 km
zonally in the North Atlantic Ocean. The mechanisms of mixing are explored
using numerical models. The importance of incorporating such mixing via
parameterizations in ocean models will be emphasized. |
