Desert Dust and Climate : An Investigation Using an Atmospheric General Circulation Model

Part of the NATO ASI Series book series (ASIC, volume 282)

Abstract

A modeling of the atmospheric cycle of desert dust particles has been introduced within an atmospheric general circulation model to investigate the modifications of this cycle induced by climatic changes. For this purpose, simulations of the present-day and Last Glacial Maximum (LGM) climates have been performed. The results show littlle changes of the simulated atmospheric dust contents on a global scale but more important changes over some regions. However, the observed large increases over ice-caps for the LGM are not well reproduced.
