The role played by the Atlantic and Pacific, and Indian Oceans in South American climate variability is one of the topics researched by Marcelo Barreiro, Head of Atmospheric Sciences at Uruguay’s University of the Republic (UDELAR). Barreiro and his research group study climate variability and predictability on the continent in timescales varying from a single season to decades. This involves the study of regional and global oceanic processes and their impact on remote areas via atmospheric teleconnections—distant but connected climate phenomena.
