Short summary
The South Pacific Subtropical High (SPSH) is a main feature of the South American (SA) climate. We analyzed its behavior during two extreme temperature events based on paleoclimate records and climate models. The SPSH expands (contracts) in warm (cold) periods. The changes affect other elements of the SA climate like the strength of the southerly winds and the position of the westerly wind belt. Projections indicate that this expansion and its consequences will continue during the 21st century.
