Abstract
An analysis of the spatiotemporal variability of advective heat transfer in the atmosphere over the oceans in the Northern Hemisphere has been carried out for 1979–2018 based on reanalysis data. The maximum increase in the advective heat transfer intensity at the beginning of the 21st century is observed in the tropospheric layer of 850–500 hPa at the northern and southern boundaries of the regions in the Pacific Ocean. It is found that the areas of intensive heat outflow and inflow were located near the boundaries of the meridional circulation cells—in the subtropical and subpolar oceanic gyres, respectively. The interannual variability of heat transfer in both oceans is caused, as a rule, by the influence of atmospheric circulation processes. Thus, changes in the transfer characteristics within the identified areas, where an imbalance of heat advection is observed, allow us to conclude about the possible effect of heat transfer from these regions on the occurrence of air-temperature anomalies in the adjacent territories.
