Entrainment Rates and Eddy Exchange Coefficients From Reanalysis Sea Surface Salinity Data
Abstract Simple analytic models developed in this study are applied to long‐term averages of reanalysis surface salinity data to quantify two fundamental properties of ocean currents. The first model is based on the new Freshening Length schema and its application to the Irminger Current yields a ra...
