Abstract

A GCM developed at NASA/Goddard Space Flight Center was used in conjunction with White's aeolian sand flux model to produce a global potential aeolian transport map. Surface wind stress predictions were used from the output of a GCM simulation that was performed as part of the Atmospheric Model Intercomparison Project on 1979 climate conditions. The spatial resolution of this study is 4° × 5°, instantaneous 6-hourly wind stress data were saved by the GCM and used in this report. A global map showing potential sand transport was compared to drift potential directions as inferred from Landsat images from the simulated sand drift direction and the drift direction and the drift direction inferred for dune forms.
