英文摘要	In this work we analyze wind speed and solar irradiation data of high spatial and temporal res-olution for an extended area of north-western Africa including the Mediterranean Sea. We ex-ploit the ERA5 data bank compiled and maintained by the European Centre for Medium Range Weather Forecast (ECMWF). One of the new products they provide is horizontal wind speed components at a height of 100 m (modern wind turbines have a hub height between 80 and 120 m). We demonstrate that the desert area is an optimal location for windand solar electricity production for two peculiar aspects. Firstly, the wind speeds at 100 m over the Sahara are almost as large as wind speeds over the open sea. Wind speed differences between the standard 10 m altitude and 100 m level are considerably larger over the desert area than over the sea. Secondly, there are utilizable anticorrelations between local wind speeds at 100 m and surface solar radiations over the Sahara. As far as we know, such anti-correlations over our target area are not considered until very recently as an exploitable source of combined solar-wind electricity production. We provide a theoretically optimum combination of the two resources in a simple model framework. The result is that resource combinations between 60-40% and 70-30% wind-solar electricity aggregation (depending on the geographic location) provide and optimally smooth output with a minimal loss of total production achieved by either pure wind or pure photo-voltaic generation.
