PP33D:
Advanced Understanding of Tropical Hydroclimate Changes During the Pleistocene and Holocene Posters


Submit an Abstract to this Session


Session ID#: 44141

Session Description:
Tropical climate changes during the Pleistocene and Holocene are manifested as dramatic reorganizations of rainfall patterns, in contrast to the dramatic temperature swings in the higher latitudes. Despite the increasing availability of tropical paleoclimate records and model simulations, the physical mechanisms driving these changes are still unclear. We invite contributions exploring the hydrological and monsoonal changes on decadal-to-glacial timescales since the Pleistocene by natural archive data, new proxies, and simulation methods to reconstruct precipitation change from local to regional scales in the tropics and their global links. We particularly welcome proxy-model syntheses exploring physical mechanisms.
