K1 • Easterly winds are the main cause of the decoupling of the Atlantic Jet from the western Alboran Sea • Remote effects of atmospheric pressure over the western Mediterranean Sea are also of significant importance • This decoupling provokes important changes in the phytoplankton distributions in the Alboran Sea
AB The main objective of the present study is to gain insight into the response of the AtlanticJet (AJ) to the atmospheric forcing, in order to understand the hydrodynamic processes behind itsdisconnection from the Western Alboran Gyre (WAG) and the eastward displacement of the latter. Ananalysis was carried out based on observations of high frequency radar (HFR) derived currents and sealevel, numerical model simulations and satellite imagery, with particular focus on the events of intenseand endured easterlies. Among the main factors that characterize the atmospheric forcing linked tointense and persistent easterly wind events, the conjugation of the direct local wind forcing effect onthe Atlantic Inflow (AI) on the eastern side of the Strait of Gibraltar and the response of the coastalwaters in the northwestern (NW) corner of the Alboran Sea to the wind forcing over the Alboran Seaare of particular interest. In addition, the effect of the elevation surges in the Strait coming from thewestern Mediterranean Sea on reducing the AI intensity must be taken into account. These surgesappear in coincidence with the establishment of persistent and intense easterlies over the AlboranSea. The alteration of the AJ-WAG system in response to this forcing causes important changes in thephytoplankton distributions in the Alboran Sea. After the events of persistent and intense easterlies thephytoplankton accumulations in the NW Alboran Sea are displaced offshore and the phytoplanktontransported with the AJ is injected toward the central zone of the WAG.
