According to the drifter project, the waters of the central Atlantic flow east and further south. They do not cross the parallel of 45 degrees (slide 1). But the water off the coast of Norway is really abnormally warm (slide 2). As of March 11, 2013, when the radiation balance in the Arctic is negative and the water temperature is minimal, the water temperature in northern Norway was characterized by a spatial anomaly of 5°С. Quote from our monograph: "Let's consider the problem of water exchange in the oceans. The regime of the Arctic Ocean differs from the regime of the Atlantic Ocean in that about 5 thousand km3 of river water is brought to it annually (the Northern Dvina, Ob, Yenisei, Khatanga, Lena, Kolyma, Mackenzie, etc. For this reason, the waters of the Arctic (salinity 30 ‰) have a lower salinity than the waters of the Atlantic (salinity 35 ‰). In our opinion, it is important to consider in detail the features of the Arctic and Atlantic water exchange process. It is well known that water exchange through channels is formed under the conditions of the presence of sea level gradients and water density gradients, which create a corresponding pressure gradient. Even in the absence of a level difference between the Arctic and the Atlantic, water exchange occurs due to the different density of their waters. This water exchange takes place according to the open admiral S.O. Makarov's "right hand" rule. Slide 2a shows a map of the ice situation in the Arctic on December 23-29, 2012 and the currents that provide the corresponding features of the spatial ice cover. Due to the peculiarities of the spatial distribution of the slope of the ocean surface, throughout the year, water flows into the Arctic from the Atlantic along the Norwegian coast, and flows out along the Greenland coast. The spatial distribution of temperature, which fully characterizes the density of water in winter, indicates an increase in the water exchange between the Arctic and the Atlantic due to the density gradient in winter. The authors of the monograph believe that in the warm season, when the river flow into the Arctic Ocean increases, the leakage of Arctic water into the Atlantic increases sharply. Such leakage occurs according to the "Right Hand" rule along Greenland. In winter, when the river flow is sharply reduced, the inflow of warm Atlantic water into the Arctic basin also occurs according to the "right-hand" rule, along the coast of Norway. Thus, a more intensive outflow of water from the Arctic Ocean to the Atlantic as a result of a seasonal increase in the flow of rivers, the influx of warm Atlantic water into the Arctic, which softens winters in northern Europe. The melting of permafrost in Siberia and Canada is causing an increase in river flow to the Arctic and warming in Northern Europe. The effect of the "right-hand rule" forms gulfs of warm Atlantic water (not to be confused with the Gulf Stream) to Novaya Zemlya. This is a typical situation and it is the result, among other things, of the intensification of the Arctic-Atlantic water exchange and the Icelandic cyclone (slide 3)."
