 Abstract:

   In this work, we calculate climatic wind-wave and lithodynamic characteristics of the shallow part of the Black Sea, adjacent to the western coast of the Crimean Peninsula, for time period from 1979 to 2008. The original software package developed at the Institute of Problems of Mathematical Machines and Systems of the National Academy of Sciences of Ukraine and the re-analysis data of the Japan Meteorological Agency are used. The latter ones are corrected using long-term observational data on the stationary offshore platform located in the northwestern part of the Black Sea. First, a wave field is calculated over the entire Black Sea with a resolution of 1.5–3 minutes, and then on a finer unstructured grid in the region of Kalamitsky Bay. After that, the currents and lithodynamic characteristics induced in the coastal zone of the bay are calculated. It was found that in Kalamitsky Bay the maximum heights of significant waves for the period from 1979 to 2008 did not exceed 5 m. The constructed roses of wind-wave characteristics indicate the fact that the waves are most likely to propagate from the south-west, despite the fact that the typical wind here has the predominant north-north-east and south-south-west components. Obviously, this is due to the configuration of the coastline. Storms are most frequent in the cold half-year (from October to March). Their share in the total number of storms is more than 80%. This is manifested both in the climatic fields of the wind and in the climatic fields of the waves for different months. The described results generally correspond to published data obtained on the basis of analysis of long-term semi-instrumental observations at marine hydrometeorological stations in the study region. It is concluded that the software package used can be successfully used for scenario wind-wave and lithodynamic estimates in the region, which are supposed to be performed and presented in the second part of the work.

Keywords: modeling, re-analysis, Black Sea wind-wave climate.
