                         Sediment Transport (COAWST), com alt{\'{\i}}ssima

                         Opera{\c{c}}{\~a}o Ant{\'a}rtica XXXIII (OP33). As 
                         simula{\c{c}}{\~o}es realizadas com o modelo COAWST foram 
                         avaliadas considerando a temperatura da superf{\'{\i}}cie do mar 
                         (TSM) e perfis verticais de temperatura e vento. No qual 
                         verificou-se que o modelo reproduziu de forma acertada tanto a TSM 
                         como os perfis de temperatura e vento. A estabilidade e o 
                         desenvolvimento da CLAM foram analisados, considerando a 
                         modula{\c{c}}{\~a}o local de TSM e os padr{\~o}es advectivos 
                         impostos pelas condi{\c{c}}{\~o}es sin{\'o}ticas atuantes. Para 
                         isso, foram selecionados tr{\^e}s estudos de caso, sob 
                         influ{\^e}ncia de condi{\c{c}}{\~o}es pr{\'e}-frontais, 
                         frontais e p{\'o}s-frontais. Os resultados demonstraram que a 
                         CLAM foi modulada pela advec{\c{c}}{\~a}o t{\'e}rmica, 
                         condicionada pelas situa{\c{c}}{\~o}es sin{\'o}ticas 
                         atmosf{\'e}ricas analisadas e pela TSM local, assim como foi 
                         observado em alguns casos um maior desenvolvimento da CLAM 
                         associado com o incremento do vento em superf{\'{\i}}cie. Na 
                         verifica{\c{c}}{\~a}o do mecanismo de ajuste hidrost{\'a}tico, 
                         foi observado a atua{\c{c}}{\~a}o deste mecanismo no estudo de 
                         caso influenciado por condi{\c{c}}{\~o}es frontais. A 
                         an{\'a}lise do papel dos termos das equa{\c{c}}{\~o}es 
                         horizontais de momentum em superf{\'{\i}}cie evidenciou maior 
                         influ{\^e}ncia dos termos de gradiente de press{\~a}o, coriolis, 
                         advec{\c{c}}{\~a}o e tend{\^e}ncia total, assim como, uma

                         ABSTRACT: In order to study the dynamical and thermodynamic 
                         mechanisms at the oceanatmosphere interface, responsible for the 
                         stability of the Marine Atmospheric Boundary Layer (MABL), in the 
                         southwest of the South Atlantic Ocean, this work used the regional 
                         numerical modeling system Coupled Ocean Atmosphere Wave Sediment 
                         Transport (COAWST), with very high spatial resolution, and data 
                         measured in situ during Antarctic Operation XXXIII. The COAWST 
                         model simulations were evaluated considering the Sea Surface 
                         Temperature (SST) and temperature and wind vertical profiles. It 
                         was verified that the model correctly reproduced both SST and 
                         temperature and wind profiles. The MABL stability and development 
                         were analyzed, considering the local modulation of the SST and 
                         advective patterns imposed by synoptic conditions. Thus, three 
                         case studies were selected, influenced by pre-frontal, frontal and 
                         post-frontal conditions. The results showed that the MABL was 
                         modulated by thermal advection, conditioned by atmospheric 
                         synoptic conditions and local SST, as well as in some cases, a 
                         greater MABL development was associated with surface wind 
                         increment. During the case study influenced by frontal conditions, 
                         the hydrostatic adjustment mechanism was observed. The horizontal 
                         equation terms role analysis of the surface momentum showed a 
                         greater influence of the pressure gradient, coriolis, advection 
                         and total tendency, as well as a relation between the horizontal 
                         diffusion term increase and the surface wind reduction in two of 
                         three analyzed cases.",
