Summary
Volume transport in Sverdrup of the Agulhas Current (at 32°S) and the Agulhas Leakage (section at the Good Hope line). The offline ARIANE software was used to track Lagrangian particles originating in the Agulhas Current. The virtual particles are seeded in a zonal section across the Agulhas Current at 32°S over the full depth for southward velocities and are advected for a maximum period of 5 years based on the 5 d three-dimensional velocity field obtained from FOCI. Each particle is assigned a fraction of the total instantaneous Agulhas Current volume transport that remains constant as it is advected forward. An annual time series of Agulhas leakage is obtained by summing the volume transport associated with particles that exited the Cape Basin through the Good Hope section within 5 years.
