Here, we study a specific type of so called topographically generated eddies (TGE) that are often generated, in the Black Sea, due to baroclinic instability caused in a jet stream impinging on bottom irregularities. This research was focused on mesoscale eddy activity in the northeastern part of the Black Sea, particularly, on isolated and grouping...

The northeastern part of the cyclonic Rim Current, which encircles the entire basin of the Black Sea, is named as the Northeast Caucasian Current. It periodically approaches the coast, triggering the formation of topographic generated eddies, including long-living isolated anticyclonic eddies and short-living multiple anticyclonic eddies, which gro...

The Northeast Caucasian Current (NCC) is the northeastern part of the cyclonic Rim Current (RC) in the Black Sea. As it sometimes approaches the narrow shelf very closely, topographically generated cyclonic eddies (TGEs) can be triggered. These eddies contribute to intense, along- and cross-shelf transport of trapped water with enhanced self-cleani...
