A long-term (10-year) mesoscale simulation was carried out using ROMS for the Brazilian southwest coast. The results are being analyzed in terms of the baroclinic instability along a zonal section between Cabo Frio and Cabo de São Tomé, along the Rio de Janeiro coast. The instability profiles are being calculated with an adapted Johns (1988) model. Results will also be compared to global ocean simulations databases, such as MyOcean and HYCOM/NCODA, focusing on the instability profiles.
