Data sets

ERA5 hourly data on pressure levels from 1959 to present H. Hersbach, B. Bell, P. Berrisford, G. Biavati, A. Horányi, J. Muñoz Sabater, J. Nicolas, C. Peubey, R. Radu, I. Rozum, D. Schepers, A. Simmons, C. Soci, D. Dee, and J.-N. Thépaut https://doi.org/10.24381/cds.bd0915c6

Short summary

The circulation patterns of surface water over the northern Gulf of Cádiz are described based on hourly high-frequency radar data from 2016 to 2020. A persistent current follows the continental shelf slope eastward while near the coast, and currents generally have a balanced (eastward–westward) direction. In summer cross-shelf transport is promoted when westward coastal countercurrents recirculate offshore in the western region and merge with the slope current.
