Abstract

The main aim of the study is to identify in the Black Sea quasi-homogeneous spatial areas and corresponding relevant features, the climatic statistical characteristics of which will determine these areas. Numerical modeling and discriminant analysis were applied. As a result of modeling an array of wind wave parameters for the period of 45 years (1979–2023) was obtained. The values of the main parameters (significant wave heights, spectrum peak periods, propagation directions) for this period at 92 points uniformly distributed over the Black Sea were analyzed. The main features, by which the zoning of the Black Sea was carried out, were climatic repeatabilities of the following parameters: significant wave heights in the ranges of h_s< 1 m, 1 <h_s< 3 m, 3 <h_s< 5 m, h_s> 5 m; and spectrum peak periods in the ranges t_p< 3 s, 3 <t_p< 6 s, 6 <t_p< 9 s, t_p> 9 s. According discriminant analysis six quasi-homogeneous areas (clusters) in the Black Sea were identified. The main zoning parameters are wave heights in the ranges 3 <h_s< 5 m and h_s> 5 m and periods 6 <t_p< 9 s. The identified clusters are quite homogeneous in the repeatability of wave action of the north-eastern and north-western directions. The obtained quasi-homogeneous areas of the Black Sea significantly refine the zoning obtained earlier and can be used to study and forecast sea climate change.

期刊介绍： Dynamics of Atmospheres and Oceans is an international journal for research related to the dynamical and physical processes governing atmospheres, oceans and climate. Authors are invited to submit articles, short contributions or scholarly reviews in the following areas: •Dynamic meteorology •Physical oceanography •Geophysical fluid dynamics •Climate variability and climate change •Atmosphere-ocean-biosphere-cryosphere interactions •Prediction and predictability •Scale interactions Papers of theoretical, computational, experimental and observational investigations are invited, particularly those that explore the fundamental nature - or bring together the interdisciplinary and multidisciplinary aspects - of dynamical and physical processes at all scales. Papers that explore air-sea interactions and the coupling between atmospheres, oceans, and other components of the climate system are particularly welcome.
