Shifts of adulterations as the result of seasonal horizontal convection under the shelf plate (numerical modeling)



The article shows that the water dynamics induced by differential cooling in upper shelf area (down to 60 m depth) is significantly influenced by day/night variations which delays an establishing of a seasonal water-exchange in shallows. Convective exchange flows within the entire shelf region in seasonal circle requires 4—7 weeks to reach a quasisteady state. Formation of a linear portion on the horizontal temperature profile can be used as an indicator of the approaching of the flow to the steady state. Flushing time for the shelf zone under steady-state condition is 30 days and is only slightly influenced by the slope length.
