The effect of long-period variability of the speed and direction of sea surface winds, absolute geostrophic velocities on the sea surface temperature (SST) and thermal upwelling index (TUI) trends in the Canary upwelling region is considered using satellite data from 1980 to 2016. Despite the statistically significant intensification of the surface wind in the region, there were no long-term trends in the upwelling intensity (expressed in SST terms), as well as in the geostrophic velocities. It is concluded that the absence of a significant intensification of the Canary upwelling with the increase of the drift wind in the region is associated with a general weakening of the northeast trade wind due to the observed global warming.

Abstract. Sea surface wind perturbations over sea surface temperature (SST) cold anomalies over the Kashevarov Bank (KB) of the Okhotsk Sea are analyzed using satellite (AMSR-E and QuikSCAT) data during the summer-autumn period of 2006–2009. It is shown, that frequency of cases of wind speed decreasing over a cold spot in August–September reaches up to 67%. In the cold spot center SST cold anomalies reached 10.5 °C and wind speed lowered down to ~7 m s−1 relative its value on the periphery. The wind difference between a periphery and a centre of the cold spot is proportional to SST difference with the correlations 0.5 for daily satellite passes data, 0.66 for 3-day mean data and 0.9 for monthly ones. For all types of data the coefficient of proportionality consists of ~0.3 m s−1 on 1 °C.
