Russian oceanologists found out what takes heat from the Arctic seas
The press service of the university stressed that its scientists were the first in the world to study the contribution of oceanic vortices to heat transfer. The study was conducted based on the study of satellite images over the past 30 years.
"Vortices extract from currents and accumulate in the Norwegian and Greenland Seas up to a third of all heat coming from temperate latitudes. Another third goes to the Barents Sea, and the rest of the heat continues its movement to the Arctic basin," the university noted.
Oceanologists have found that the process of vortex formation can significantly reduce the amplitude of temperature anomalies. However, according to the researchers, the data do not give a complete picture of the heat balance in the Arctic seas, there are probably other little-studied oceanic processes affecting heat transfer in the oceans.
Earlier it became known that climate change could lead to the fact that the Arctic will lose its long-term ice reserves, the acceleration of the water cycle in the Arctic can affect the entire ecosystem, the ice in the Arctic has become thinner, and their life is shorter, ttelegraf.ru writes.
