| Abstract: | By using the data array of satellite measurements of the sea-surface temperature (SST), it is shown that the distributions
of linear trends of the SST for 17 years (1986–2002) are closely correlated with the specific features of large-scale circulation
of waters. The extreme values of trends of the SST are observed in the zones of the Gulf Stream, East-Greenland, Labrador,
and North-Atlantic Currents, North Equatorial Countercurrent, South Equatorial and Antarctic Circumpolar Currents. The differences
between the distributions of trends of the SST for some months of the year are revealed. In the zones of currents transporting
warm surface waters from the tropical areas, positive trends of the SST are observed for the most part of the year. On the
contrary, negative trends are predominant in the zones of currents transporting cold upwelling waters.
