Meteorologically-driven circulation and flushing times of the Bay of Algeciras, Strait of Gibraltar Sánchez-Garrido, José Carlos García-Lafuente, Jesús Sammartino, Simone Naranjo-Rosa, Cristina Belén De los Santos, F.J. Álvarez-Fanjul, Enrique Meteorología marina - Algeciras A primitive-equation model has been used to investigate the meteorologically-driven circulation of the Bay of Algeciras. It is shown that the mean circulation of Atlantic Water (AW) is characterized by an anticyclonic cell, while Mediterranean Water (MW) follows a preferred cyclonic pathway. Meteorological forcing distorts substantially the AW mean circulation pattern, and only modulates that of the MW. Winds drive a vertical circulation cell in the Atlantic layer consistent with Ekman dynamics, whereas the horizontal circulation pattern is markedly dependent on the swift Atlantic jet entering the Mediterranean and changes from clearly anticyclonic to cyclonic as the jet separates or approaches the strait’s northern shoreline. This occurs through atmospheric pressure-driven acceleration/deceleration of the jet, in agreement with internal hydraulics theory predictions. It is also found that the renewal of AW is largely modulated by tides, with meteorological forcing playing a secondary role. The opposite applies to the renewal of MW. 2024-09-25T16:41:35Z 2024-09-25T16:41:35Z 2014-03-15 journal article Sánchez-Garrido, J. C., Lafuente, J. G., Sammartino, S., Naranjo, C., de los Santos, F.
