Surface waters are traced with numerical Lagrangian particles transported in the velocity field of three different ocean models with horizontal resolutions that range from 1/4° to 1/32°. The connections resulting from the large-scale convergent Ekman dynamics agree qualitatively but are strongly modulated by eddy variability that introduces meridional asymmetry in the amplitude of transport. Lagrangian forward-in-time integrations are used to analyze the fate of particles originating from the central regions of the convergence zones and highlight specific outflows not yet reported for the southeastern Pacific when using the currents at the highest resolutions (1/12° and 1/32°). The meridional scales of these outflows are comparable to the characteristic width of the fine-scale striation of mean currents. specialized PACIFIQUE 032 43 8 [en ligne] 2016 https://www.documentation.ird.fr/hor/fdi:010066611 10.1002/2016GL068217 [F B010066611] https://www.documentation.ird.fr/hor/fdi:010066611 https://www.documentation.ird.fr/intranet/publi/depot/2016-04-08/010066611.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-04-08 2016-07-12 fdi:010066611 fre
