We use a high-resolution numerical model toanalyze the hydrodynamical exchange processes of the CienfuegosBay with the Caribbean Sea. Results show that freshwaterinputs and wind are the main factors controlling the waterexchange in the bay. Nine simulation case studies with threewind conditions and three freshwater inputs were carried out.The main conclusion is that the Cienfuegos Bay system has aslow exchange rate, with an average flushing time of 39 daysduring the rainy period and 50 days during the dry one, forthe most probable wind direction. Two new temporary scalesfor Cienfuegos Bay are discussed: the local e-flushing time andthe flushing lag. The results obtained for these new variablesvalidate the slow exchange capacity of the bay.
