SUMMARY:

The thesis project will investigate the influence of variations in the Sea Surface Temperature (SST) of the Benguela Current on climate variability in the tropical belts of Africa and South America. This research is important for understanding how regional oceanic phenomena can drive large-scale atmospheric and oceanic changes, a process known as teleconnections. To achieve this, the thesis project employs the SPEEDY-TOM3 coupled model, a dynamic tool capable of simulating the complex, bidirectional interactions between the ocean and the atmosphere in an integrated manner. Through this model, two distinct 60-year simulations will be conducted: one experiment focusing on a scenario of Benguela Gulf SST warming, and another on a scenario of SST cooling in the same region. Canonical processes will be used to create these two scenarios. The central objective is to understand the propagation mechanisms of these teleconnections by analyzing how changes in the Benguela Current's SST impact distant climate systems. This is achieved through a comprehensive analytical framework that combines statistical metrics, to quantify anomalies and patterns, with dynamic analyses of atmospheric and oceanic circulation. This dual approach will not only allow for the identification of correlations but also for the explanation of the underlying physical processes, such as changes in atmospheric pressure systems, wind fields, and moisture transport routes. The direct comparison of results between the two experiments should provide a foundation for a detailed understanding of how the Benguela Current acts as a driver of climate variability.
