Fig. 1: The eddy-rich ocean model INALT20 is used to estimate Agulhas leakage (AL) via Lagrangian particle tracking (ALLA), to update an existing method to reconstruct AL from sea surface temperature (ALSST), and to establish a new Lagrangian method to reconstruct AL from sea surface height (ALLA-SSH).

a 5-day mean snapshot of simulated upper ocean (134 m) current speed. b Release (AC) and sampling (GH) sections for the Lagrangian simulations performed to estimate ALLA, exemplary leakage and no-leakage trajectories are displayed in red and gray lines, respectively. c 5-day mean snapshot of simulated near surface (16 m) temperature, boxes used to calculate the temperature difference between the South Atlantic (SA) and Indian Ocean (IO) used for the ALSST estimation are added. d 5-day mean snapshot of sea surface height (SSH) anomaly (global mean subtracted) used to calculate geostrophic velocities for the new Lagrangian ALLA-SSH estimation, satellite track employed for the old ALSSH estimate by Le Bars et al. (2014) is overlayed.
