Изучение процессов теплообмена и распределения потоков тепла в океанах имеет важное значение для понимания климатических изменений на Земле. Северная Атлантика, являющаяся одним из ключевых компонентов глобальной климатической системы, играет существенную роль в регулировании климата наших широт.Одним из ключевых инструментов для анализа распределения тепла в океанах является вероятностный анализ. В настоящей работе методами математического моделирования проводится статистический анализ данных наблюдений тепловых потоков в Северной Атлантике.Материалы и методы. Используемые методы включают в себя анализ случайных процессов, заданных стохастическим дифференциальным уравнением (СДУ) или уравнением Ито, аппроксимацию данных наблюдений и решение уравнения Фоккера-Планка-Колмогорова (ФПК) для описания эволюции вероятностного распределения тепла в океане.Результаты исследования. С помощью методов математического моделирования проведен вероятностный анализ распределения потоков тепла в Северной Атлантике за период с 1979 по 2022 годы. Результаты исследования позволили установить закономерности распределения потоков тепла в изучаемом регионе за рассматриваемый период времени.Обсуждение и заключения. Полученные результаты могут быть полезными для дальнейшего изучения климатических процессов в Северной Атлантике, а также для разработки стратегий управления ресурсами и защиты окружающей среды.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. The study of heat interaction processes and the distribution of heat flaxes in the oceans is important for understanding climate change on Earth. The North Atlantic, which is one of the key components of the global climate system, plays a significant role in regulating the climate of our latitudes. One of the key tools for analyzing heat distribution in the oceans is probabilistic analysis. In this work, using mathematical modelling methods, a statistical analysis of observational data on heat fluxes in the North Atlantic is carried out.Materials and Methods. The used methods include the analysis of random processes specified by the stochastic differential equation (SDE) or the Ito equation, approximation of observational data, and solution of the Fokker-Planck-Kolmogorov (FPK) equation to describe the evolution of the probabilistic distribution of heat in the ocean.Results. Using mathematical modelling methods, a probabilistic analysis of the distribution of heat fluxes in the North Atlantic for the period from 1979 to 2022 has been carried out. The results of the study made it possible to establish patterns of distribution of heat flux in the studied region over the period of time under consideration.Discussion and Conclusions. The results may be useful for further study of climate processes in the North Atlantic, as well as for the development of resource management and environmental protection strategies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>случайный процесс</kwd><kwd>стохастическое дифференциальное уравнение</kwd><kwd>уравнение Фоккера-Планка-Колмогорова</kwd><kwd>поток тепла</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Random process</kwd><kwd>stochastic differential equation</kwd><kwd>Fokker-Planck-Kolmogorov equation</kwd><kwd>heat flow</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках государственного задания, тема № FMWE-2024-0016.</funding-statement><funding-statement xml:lang="en">The research was carried out within the framework of a state asignment, topic No. FMWE-2024-0016.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gorshenin A., Osipova A., Belyaev K.
