To detect eddies from the GLORYS12 outputs, we adopt the widely used winding-angle (WA) method (Nencioli et al., 2010; Yan et al., 2024; Yang et al., 2013). The WA method is based on the geometric characteristics of instantaneous streamlines and selects an eddy when the following situations are satisfied. WebAbstract.
