AbstractThe confluence of the Malvinas and Brazil currents over the Argentine Basin give the region chaotic dynamics and severely limit potential predictability. To probe the forecast horizon for ocean surface quantities of temperature and carbon, we construct regional models of the Argentine Basin with biogeochemistry at 1/3° and 1/12° resolution and design a series of experiments. We add positive and negative zonal wind stress anomalies over small and large areas during a short period in different model runs. We calculate the response of the surface temperature and DIC. The 1/3° model maintains predictability for up to 45 days, while the 1/12° model has a shorter window of about two weeks. However, the 1/3° model response is only consistent with the 1/12° model for about 8 days calling into question the potential predictive skill of the coarser model at longer lead times.
