Abstract: | The analysis of surges in the Sea of Azov is carried out on the basis of three-dimensional nonlinear model using the prognostic fields of near-water wind and atmospheric pressure. Carried out is the comparison of the results of numerical computations with the data of direct measurements of the sea level at a number of coastal stations. Studied is an effect of atmospheric impact intensity variations on the maximum values of sea level deviations and current velocities, as well as on the admixture transformation features. The analysis of results of numeric computations enabled to make a conclusion on the dependence of the pollution dissipation time on the wind speed and on the location of pollution areas. |
