Abstract

This paper focuses on numerical modelling of an extreme surge in the Taganrog Gulf on March 24, 2013 to study its formation features and identify the requirements for an accurate reproduction of atmospheric and marine circulation in the Sea of Azov. Two versions of the three-dimensional σ-model of marine circulation INMOM (Institute of Numerical Mathematics Ocean Model) with different spatial resolutions of ~4 km and ~250 m were originally used. Additionally, two types of atmospheric forcing were used during the simulations of these models: Era-Interim reanalysis and WRF (Weather Research and Forecast Model) model data. The paper shows that, according to the obtained results, the accuracy of an extreme surge reproduction in the Sea of Azov was more dependent on the quality of atmospheric forcing than on the spatial resolution of the marine circulation model. Additional simulations were performed with three different configurations within the INMOM version with a spatial resolution of ~250 m and with the use of the WRF atmospheric forcing. Configurations varied in types of the model: baroclinic, barotropic and shallow water approximation. However, simulation results of the models with different configurations were practically identical to each other.
