| Resumo | This study summarizes the main findings of the program named Air-Sea Interaction at Brazil-Malvinas Confluence (INTERCONF) under the High Latitudes Oceanography Group (GOAL). This program, under the umbrella of the Brazilian Antarctic Program (PROANTAR) leads scientific cruises across the BMC region once a year. This is made during the Austral spring when simultaneous oceanic and atmospheric observations were made onboard of a Brazilian vessel. A total of 6 cruises have been performed to date, from 2004 to 2009, covering different periods within the typical synoptic cycle of the region. The data taken from oceanic and atmospheric measurements performed simultaneously at the Brazil-Malvinas Confluence (BMC) region at the Southwestern Atlantic Ocean have revealed lateral temperature gradients as high as 0.3°C.km-1 at the surface and sub-surface. In the Oceanic Boundary Layer (OBL), the vertical temperature gradient reaches 0.08°C.m-1 at 500 m depth. Our results show that the Marine Atmospheric Boundary Layer (MABL) at the BMC region is modulated by the strong sea surface temperature (SST) gradients present at the sea surface. The mean MABL structure is thicker over the warm side of the BMC where Brazil Current (BC) waters predominate. The opposite occurs over the cold side of the confluence where waters from the Malvinas (Falkland) Current (MC) are found. The warm side of the confluence presented systematically higher MABL top height compared to the cold side. This type of modulation at the synoptic scale is consistent to what happens in other frontal regions of the World Ocean, where the MABL adjusts itself to modifications along the SST gradients. Our results suggest that the sea level pressure (SLP) is also modulated locally, together with static stability vertical mixing mechanism, by the surface condition during all cruises. Post and pre-frontal conditions produce opposite thermal advections in the MABL, that lead to different pressure intensification patterns across the confluence. At the same time, a synoptic cycle can be identified at the region, marked by the successive passages of frontal systems and extratropical cyclones. The different phases of the synoptic cycle lead to different thermal advections at the confluence, causing respective different patterns of atmospheric boundary layer adjustment to the surface heterogeneity induced by the confluence. Furthermore, our study shows that peculiar transitional characteristics are also observed between the conditions of well-established warm and cold advection. At many phases of the synoptic cycle, very stable boundary layer occurs at one or both sides of the confluence. Some of the observed characteristics, such as a large moisture accumulation near the surface suggest that existing sensible and latent heat fluxes parameterizations fail under very strong stratifications and the consequences of this deficiency are analyzed. |
