                         BrasilMalvinas, foram estudados em dois casos de intensidade do 
                         gradiente de TSM distintos, um mais intenso e outro menos intenso, 
                         e sob duas condi{\c{c}}{\~o}es atmosf{\'e}ricas diferentes.

                         foram analisados os processos din{\^a}micos e termodin{\^a}micos 
                         em transectos perpendiculares e paralelos ao gradiente de TSM. O

                         effects of the thermal oceanic front on the Marine Atmospheric 
                         Boundary Layer (MABL), in the BrazilMalvinas Confluence (BMC) 
                         region, were studied. This was based in two cases of SST thermal 
                         gradient intensities. One was more intense and the other less 
                         intense. Both cases were studied under two different atmospheric 
                         conditions. Using highresolution numerical model, we simulate and 
                         analyzed the dynamic and thermodynamics of it, over two 
                         orientations transects. One was perpendicular and the other 
                         parallel to the SST thermal orientation gradient. The main 
                         objective of this study was to analyze on which conditions the 
                         mechanisms of vertical mixing and pressure adjustment occur in 
                         MABL. Through of the terms of the momentum equation and heat 
                         fluxes, it was observed that the mechanisms of pressure adjustment 
                         and vertical mixing coexist under the two synoptic conditions 
                         analyzed and operate in different ways on one side and the other 
                         of the SST front. Under the presence of an atmospheric high 
                         pressure system the MABL is locally modulated by the SST and 
                         responds to the forcing, in which the minor order terms of the 
                         trend equation can be neglected, since it is a quasigeostrophic 
                         situation. On the other hand, under the influence of a low 
                         atmospheric pressure system MABL is influenced by dynamic 
                         mechanisms, which terms of friction and advection are in the same 
                         order of pressure gradient force.",
