With the use of three-dimensional nonlinear mathematical model dynamic processes and features of transformation are studied admixtures in the Sea of Azov, caused the action of variable wind and atmospheric pressure at presence of stationary currents. On the basis of results of numeral calculations conclusions are done about influence of sizes of speeds of stationary flows on the maximal rejections of level and speed of non-stationary currents, generated the fields of wind, SKIRON got on an atmospheric model. The analysis of influence of change intensity of stationary flows is executed on the sizes of areas of drainage and submergence in off-shore districts exterminating depending on the angle of slope (getting up) of relief of waterside area. It is set that the united action permanent and wind was simulated with the SKIRON weather forecasting system result in the substantial increase of area of distribution of passive admixture and time of its dispersion as compared to influence only of stationary currents.
Keywords: numerical modeling, sigma-coordinate model, dynamic processes, stationary currents, areas of drainage and submergence
Mots-clés : evolution of passive admixture.
