Аннотация: The characteristics of the eddy mass transport are estimated depending on the values of the parameters of a large-scale flow that forms under the conditions of the shelf seas in the Arctic. For this, the results of numerical simulation of five Arctic seas with a horizontal resolution permitting the development of mesoscale eddies are used. The parameters obtained in numerical experiments are considered as a statistical sample and are analyzed for their independence. Further clusterization in space of found set of most independent variables allows to identify several separate types of eddies. The features of the resulting clustering are described and discussed in the presented work.

Ключевые слова: eddy mass transport, subgrid-scale processes, parametrization, clustering.
