Impact of millennial-scale Atlantic meridional overturning circulation (AMOC) changes on tropical South American precipitation during the last glacial period

Abstract

Future evolution of tropical rainforest and biodiversity across South America is of great concern to scientific community, policy maker and general public. Understanding this issue depends greatly on our knowledge about the response of tropical South American precipitation to the Atlantic meridional overturning circulation (AMOC) slowdown under global warming scenario, which however never occurred throughout the era of instrumental data. This thesis thus refers to similar states of the AMOC reduction in the past, e.g., the Heinrich Stadials (HS) and the Dansgaard-Oeschger (DO) Stadials during the last glacial period, to explore the ocean-atmosphere interaction over tropical South America.
