Стоксов дрейф, генерируемый поверхностным волнением, влияет на множество физических процессов, проистекающих в береговой зоне моря, в том числе на перенос тепла и соли, а также транспорт загрязняющих веществ. Учет параметров морских течений, вызываемых дрейфом Стокса, важен для более корректного описания общей гидродинамической структуры прибрежных вод. Кроме того, морские течения, генерируемые поверхностным волнением, могут вносить существенный вклад в процессы накопления и перераспределения загрязняющих веществ в прибрежной зоне моря. Представлены результаты исследований стоксова дрейфа на северо-восточном шельфе Черного моря в районе г. Геленджика за отрезок времени с 2003 по 2022 г. Выявлены сезонные и межгодовые особенности изменчивости скоростей и направлений течений Стокса. Показано, что с декабря по апрель, за исключением февраля, стоксов перенос обладает сопоставимыми повторяемостями по направлениям к берегу, от берега и на северо-запад...
The Stokes drift generated by surface waves affects many physical processes occurring in the coastal zone of the sea, including heat and salt transport, as well as transport of pollutants. Taking into account the parameters of sea currents caused by the Stokes drift is important for a more correct description of the general hydrodynamic structure of coastal waters. Moreover, sea currents generated by surface waves make a significant contribution to the processes of accumulation and redistribution of pollutants in the coastal zone of the sea. The article presents the results of the study of the Stokes drift on the northeastern shelf of the Black Sea near Gelendzhik for the period from 2003 to 2022. Seasonal and interannual features of variability of Stokes current velocities and directions have been identified. It has been shown that from December to April, excluding February, the Stokes transport has comparable repeatability in directions towards the coast, away from the coast, and towards the northwest. In February, the main flow tends to the open sea. In May and June, the repeatability of currents towards the coastline increases significantly, with the contribution of currents to the southeast increasing at the beginning of summer. In July, the currents directed to the southeast and away from the coast become almost identical in terms of repeatability. From August to November, the proportion of currents directed away from the coast increases with a gradual decrease in the repeatability of currents towards the southeast. In multi-year terms, the flow directed away from the coast to the open sea prevails (repeatability of 34.3%). The same flow has the highest mean velocity (0.053 m/s). Repeatability of the long-shore currents directed towards the southeast and northwest is almost the same, but the currents towards the northwest are much more intense.
