STUDYING OF STATISTICAL CHARACTERISTICS OF EXTREMAL WIND WAVES ON COASTAL ZONE OF THE BLACK SEA ACCORDING TO THE DATA PRESENTED BY STATE HYDROMETEOROLOGICAL SERVICE OF UKRAINE

Evstigneev V.P., Naumova V.A., Evstigneev M.P.

In this publication a statistical characteristics of extremal wave heights on the Ukrainian coast of the Black sea have been studied, using the data of standard observations performed on marine network stations of the State hydrometeorological service of Ukraine. It is shown for the first time that distribution of maximal wave heights corresponds to Gumbel distribution; statistical distribution of storm occurrence (to be accompanied with wave heights more than 3m) in the period of the most intensive storm activity corresponds to Poisson distribution. Corresponding numerical parameters of distributions has been obtained.

Keywords: wind-wave anomalies, storms, Azov-BlackSea region, Gumbel distribution, Poisson distribution.
