Abstract—The intensification of the Main Black Sea (Rim) Current caused by wind forcing is revealed to be
accompanied by the weakening of the mesoscale eddy dynamics and the associated horizontal (trans-shelf)
water exchange, while the relaxation of the Rim Current in the absence or reduction of the wind (Ekman) forc-
ing leads to the opposite effect. This conclusion is made on the basis of the results of a joint analysis of the wind
field characteristics (NCEP), satellite infrared imagery, and ship hydrological observations, as well as from the
results of laboratory experiments on the modeling of physical mechanisms of the variability of the macro- and
mesoscale dynamics of the Black Sea waters.
