Climate change and its impacts in the South Atlantic Ocean

The oceans are a complex system, connected in multiple ways with many complicating factors that are introduced by the geometry of ocean basins, the presence of land boundaries, atmospheric forcing, interaction with the cryosphere and biosphere and variations associated with the dynamics of the continental shelf. In additionm observation difficulties and its high cost in real time, creates a serious problem of sampling which is partly resolved through the use of numerical modeling results where the low spatial resolution of the global general circulation models are nested to isolated components (atmosphere, ocean, land surface, etc. ..) with ability to solve regional scales of motion.

Climate models are the traditional tools used to generate projections of future climate using the various development scenarios. These global models are highly complex, but the low resolution of 200 km is not in any way suitable for regional studies. In this project, whose focus is to evaluate impacts and vulnerability to climate change in the region of the South Atlantic Ocean (OAS). The regional climate is predominantly affected dynamics that occurs on high resolution spatial and temporal scales. As a result, global circulation models can not explicitly capture the dynamic structure (and physical complexity) of high-resolution which are absolutely necessary for the evaluation of climate impacts.

The importance of high resolution (keeping the physical complexity) climate scenarios for studies of ocean impacts and adaptation to climate change is a matter still on the frontier of scientific research, whose importance has been recognized by the productive sectors of society. The specific objective of this project is to obtain sub-regional scale climate projections for the Southwest Atlantic Ocean in order to assess their impacts.
