Abstract. Climate evolves following natural variability and knowledge of these trends is of paramount importance to understand future scenarios in the frame of global change. Obtaining local data is also of importance since climatic anomalies depend on the geographical area. In this sense, the Canary Current is located in one of the major eastern boundary current systems of the oceans and is mainly driven by the Trade Winds. The latter promotes Ekman transport and give rise to one of the most important upwelling zones of the word in the Northwest African coast. Nearly 30 years ago, Bakun raised a hypothesis contending that coastal upwelling in eastern boundary upwelling systems (EBUS) might be intensified as the effect of global warming due to the enhancement of the Trade Winds as the effect of increasing pressure differences between the ocean and the continent. Using available NCEP/NCAR wind data north of the Canary Islands from 1948 to 2017, we show that Trade Winds intensity experienced a net decrease of 1 m s-1. Moreover, theses winds are strongly influenced, as expected, by the large-scale atmospheric patterns, such as the North Atlantic Oscillation (NAO). In addition, we found a relationship between the wind pattern and the Atlantic Multidecadal Oscillation (AMO), indicating that the ocean contributes to the multidecadal atmospheric variability in this area of the ocean with a considerable lag (> 10 years).

Short summary
We analyzed changes in wind patterns during the last 70 years (1948–2017) in the Canary Current area, located in one of the major upwelling regions in the world, using monthly NCEP wind data. Results demonstrate that Trade Winds were quite stable in direction but they suffered a significant net decrease of 1 m s-1 in intensity. We also found significant correlations between the NAO index and the wind direction and intensity, specifically in winter, and between the AMO index and the wind direction.
