| Resumo | The Brazil-Malvinas Confluence (BMC) region is acknowledged as one of the most energetic regions of the World´s Ocean. This region is characterized by the meeting of two opposing boundary currents: the Brazil and the Malvinas currents. At the Confluence, tropical warm and saline waters, transported by the Brazil Current (BC), interact with subantarctic cool and less saline waters of the Malvinas Current (MC), forming an active and nonsteady meandering frontal region. Moreover, due to the BMC closeness to the continent, its impact over the regional climate may be significant, although this issue has never been thoroughly investigated. This work presents novel simultaneous in situ ocean-atmosphere (OA) observations at the BMC region based on observational data collected simultaneously at both the Marine Atmospheric Boundary Layer (MABL) and the Oceanic Boundary Layer (OBL) on board the Brazilian Navy R/V Ary Rongel in November 2004. To our knowledge, this is the first simultaneous observation of the MABL and the OBL in the region. Furthermore, it is expected that the MABL would be affected by the BMC dynamics due to its high spatial-temporal variability. Our results show that air-sea exchanges are closely correlated with the SST fields. Heat flux calculations range from 110 W.m-2 over warm waters down to 18 W.m-2 over cold waters. High values of heat flux and air-sea temperature differences are associated with relatively strong near-surface winds. On the absence of strong large-scale synoptic systems, our observations suggest that MABL is modulated by the strong local sea surface thermal gradients. These measurements have shown that OA exchanges are closely related to the SST fields: weak (strong) winds are observed over cold (warm) waters in a cool (warm) atmosphere, which indicates a stable (unstable) MABL. This suggests that the MABL is modulated at the synoptic temporal and spatial scale by strong surface thermal gradients between the warm Brazil and the cool Malvinas currents. This process has been documented at the synoptic scale for other regions around the world but not yet for the BMC region. The prevailing mechanisms between the local forcing, which induce the MABL-OBL interaction, and the large scale on modulating the air-sea interaction are still an open issue and deserve further investigation. A new cruise is going to take place November 2005 and the same sampling strategy will be repeated. | |||
