Change in the wind flow regime in stratified lakes

Wind flows in meromictic saline lakes in which the water column does not mix to the bottom for at least one year are studied. This leads to the formation of the upper and depth layers with small density gradients, between which there is a water layer with a large density gradient. It has been shown that, depending on the density stratification and the wind speed, wind flows (in a vertical plane) of two types are possible: with one or two circulation zones. For a two-layer lake model, a criterion for the change in the wind flow regime is proposed.
