Расчеты проведены по среднегодовым данным тепловых характеристик поверхности воды и компонентам теплового баланса с пространственным шагом 4о за 1979–2024 гг. Порядок отрицательного потока энтропии ~3 . 10–2 W/m2K, и эта величина имеет временную тенденцию приближения к нулю. Сделана оценка средней скорости диссипации механической (турбулентной) энергии на единицу массы ~2 . 10–7 m2/c3. Обсуждается разность трендов тепловых характеристик вследствие «открытости» и «закрытости» полярных акваторий Тихого океана в южном и северном полушариях. Отмечается возможность обратной связи параметров в направлении климатической устойчивости. Приближение потока энтропии к нулю уменьшает динамические процессы. Деградация движений увеличивает меридиональную разность температур между нагревателем (тропики) и холодильником (полюсы). Это приводит к обратному процессу – увеличению потока энтропии и возвращению океана к предыдущему стационарному состоянию.</p></abstract><trans-abstract xml:lang="en"><p>Climatic trend of the entropy flux across the water-air boundary is determined for the oceanographic section along 180o meridian in the Pacific Ocean. The flux is calculated on the average annual data for SST and components of heat balance with 4-degree spatial resolution for 1979–2024. The flux is negative with the value ~3 . 10–2 W/m2K and has a tendency toward zero. Mean rate of the turbulent energy dissipation per unit mass is evaluated as ~2.10–7 m2/s3. Different trends in thermal conditions for the «closed» and «open» polar areas in the Southern and Northern Hemispheres, respectively, are discussed. Possible feedback of the parameters toward climate stability is noted: the lower the entropy flux, the weaker water dynamics, and the higher SST difference between tropical and polar zones, that leads to reverse process of increasing the entropy flux and returns the ocean back to its previous stationary state.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Тихий океан</kwd><kwd>поверхность океан–атмосфера</kwd><kwd>баланс потока тепла</kwd><kwd>климатический тренд</kwd><kwd>поток энтропии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Pacific Ocean</kwd><kwd>ocean-atmosphere boundary</kwd><kwd>heat flux balance</kwd><kwd>climatic trend</kwd><kwd>entropy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность рецензентам за ценные замечания, полученные при подготовке работы.
