In this paper we examine the mechanisms of variability of the oceanic heat flux in the Norwegian Current (across the Svinoy section in the southern Norwegian Sea) in 1993–2019. GLORYS oceanic reanalysis with a spatial resolution of 1/12° is used. It is found that the variability of oceanic heat flux is associated with that of water transport, which, in turn, is associated with variability of the sea level gradient across the Norwegian Current. It is shown that an increase in water transport of the Norwegian Current is a result of a decrease of the atmospheric pressure over the central part of the Norwegian Sea. The latter intensifies the southwesterly winds along the Scandinavian Peninsula. The sea level gradients across the Norwegian Current, formed by the winds, are primarily associated with Ekman pumping towards the coast, as well as with the wind stress curl. Both have a significant impact on the variability of water transport through the section. Another factor is variability of the steric sea level gradient, which significantly affects the water transport during the period of a rapid temperature rise of in the Norwegian Current (1995–2005).</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324213312">Более 90% океанического тепла поступает в Северный Ледовитый океан с Норвежским течением. В данной статье исследуются причины изменчивости океанического потока тепла с Норвежским течением (через разрез Свиной в южной части Норвежского моря) за 1993–2019 гг. Для анализа используются данные океанического реанализа GLORYS с пространственной дискретностью 1/12°. Было показано, что межгодовые колебания океанического потока тепла определяются изменчивостью расхода, который, в свою очередь, связан с изменениями градиента уровня моря через Норвежское течение. Показано, что увеличение расхода Норвежского течения происходит при понижении атмосферного давления над центральной частью Норвежского моря, что усиливает юго-западные ветра вдоль Скандинавского полуострова. Формируемые градиенты уровня моря через Норвежское течение связаны как с экмановским нагоном, так и с ротором поля ветра. Они оказывают существенное влияние на изменчивость расхода Норвежского течения в исследуемой области. Дополнительным фактором является изменчивость стерического градиента уровня моря, который влияет на изменчивость расхода только в период быстрого роста температуры воды Норвежского течения (1995–2005 гг.).</p></trans-abstract><kwd-group xml:lang="en"><kwd>Svinoy section</kwd><kwd>oceanic heat flux</kwd><kwd>discharge</kwd><kwd>Norwegian Current</kwd><kwd>GLORYS</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>разрез Свиной</kwd><kwd>океанический поток тепла</kwd><kwd>расход</kwd><kwd>Норвежское течение</kwd><kwd>GLORYS</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Башмачников И.Л., Юрова А.Ю., Бобылев Л.П., Весман А.В.
