                         between the Brazil Current (BC) and the Brazilian Coastal Current 
                         (BCC) on the local Marine Atmospheric Boundary Layer (MABL) is 
                         investigated here. This front is typical of wintertime in the 
                         Southern Brazilian Continental Shelf (SBCS) and this is the first 
                         time that its effects are investigated over the above MABL. Here 
                         we analyze variability, vertical structure, and stability of MABL 
                         as well as heat fluxes at air-sea interface, across five 
                         oceanographic transects in the SBCS made during a winter 2012 
                         cruise. Local thermal gradients associated with mixing between 
                         distinct water masses, play an essential role on MABL modulation 
                         and stability. Although weaker when compared with other frontal 
                         regions, the cross-shelf thermal gradients reproduce exactly what 
                         is expected for open ocean regions: Stronger (weaker) winds, lower 
                         (higher) sea level pressure, and a more unstable (stable) MABL are 
                         found over the warm (cold) side of the oceanographic front between 
                         the BC (warm) and coastal (cold) waters. Our findings strongly 
                         support the coexistence of both known MABL modulation mechanisms: 
                         the static and hydrostatic MABL stability. This is the first time 
                         that these modulation mechanisms are documented for this region. 
                         Turbulent fluxes were found to be markedly dependent on the 
                         cross-shelf SST gradients resulting in differences of up to 100 
                         W.m\−2 especially in the southernmost region where the 
                         gradients were more intense.",
