A New Look at the Vertical Shear of the Geostrophic Current. Part I: Dense Current.

Many appropriate and necessary phenomena and mechanisms have essential roles for transfer and diffusion of arriving solar radiation, from tropical regions to high latitudes in northern hemisphere and low latitudes in southern hemisphere. Atmospheric movements (winds) and oceanic movements (currents) are some parts of these mechanisms. Even different shear of them (movements) including vertical shear of them; have basic roles in the subject. Our goal in this research is familiarizing with oceanic efforts for transfer of sensible heat via dense current that is vertical shear of geostrophic current. In connection with the subject; three versions of dense current were introduced. Furthermore; baroclinic environment, geostrophic current and variation of it with respect to depth, definition of dense current, deriving of dense current vector in Cartesian Coordinates System, the other view to derive other equations of dense current, relation between dense current and geopotential thickness, other view of relation between dense current and geopotential thickness, and other subject related to dense current; have discussed expanded upon the research. Also, study of dense current can enlighten deep sea dynamics and helps to better understanding climate of deep oceans.
