Western Pacific thermocline structure and the Pacific marine Intertropical Convergence Zone during the Last Glacial Maximum
Paleoclimate proxy evidence suggests a southward shift of the Intertropical Convergence Zone (ITCZ) during times of Northern Hemisphere cooling, including the Last Glacial Maximum, 19–23 ka before present. However, evidence for movement over the Pacific has mainly been limited to precipitation reconstructions near the continents, and the position of the Pacific marine ITCZ is less well constrai...
متن کاملQuantifying the Effects of Lower Sea Level on Tropical Pacific Climate during the Last Glacial Maximum
ACKNOWLEDGEMENTS First and foremost, I wish to thank my research advisor and co-advisor, Dr. Kim Cobb and Dr. Emanuele DiLorenzo. They have put a tremendous number of hours into this project while teaching me that conducting research is challenging, tiring, but more importantly, fun and inspiring. I also wish to thank Dr. Yen, both who introduced me to the world of academia. Working in both of ...
متن کاملSurface temperature control in the North and tropical Pacific during the last glacial maximum
Based on coupled modelling evidence we argue that topographically-induced modifications of the largescale atmospheric circulation during the last glacial maximum may have led to a reduction of the westerlies, and a slowdown of the Pacific subtropical gyre as well as to an intensification of the Pacific subtropical cell. These oceanic circulation changes generate an eastern North Pacific warming...
متن کاملDynamical and observational constraints on tropical Pacific sea surface temperatures at the last glacial maximum
Asynchronously coupled atmosphere and ocean general circulation model simulations are used to examine the consequences of changes in the west/east sea-surface t mperature (SST) gradient across the equatorial Pacific at the last glacial maximum (LGM). Simulations forced by the CLIMAP SST for the LGM, where the west/east SST gradient across the Pacific is reduced compared to present, produce a re...
متن کاملThe role of ocean-atmosphere interactions in tropical cooling during the last glacial maximum
A simulation with a coupled atmosphere-ocean general circulation model configured for the Last Glacial Maximum delivered a tropical climate that is much cooler than that produced by atmosphere-only models. The main reason is a decrease in tropical sea surface temperatures, up to 6 degrees C in the western tropical Pacific, which occurs because of two processes. The trade winds induce equatorial...
