Abstract

Analysis of the surges on the hydrometeorological stations in the Sea of Azov is fulfilled to assess the general regularity of storm surges occurrence, including full information on timing, frequency, and conditions for the storm. An approach is proposed for estimating the statistical characteristics of extreme sea levels and their duration in correlation with local wind currents and types of synoptic situations over the Sea of Azov, obtained by the method of constructing self-organizing maps of surface atmospheric pressure and wind current. The research can be useful for the development of empirical models of the surge prediction and the validation of the numerical simulation of storm surges. It will improve the accuracy of model and forecast estimates for especially dangerous phenomena.
