Desert Dust in the Global System

Front Cover
Springer Science & Business Media, Sep 5, 2006 - Science - 288 pages

Dust storms, produced by the removal of surface materials from the world’s drylands, are a vital component of the environment. This is because of their role in biogeochemical cycling, their potential influence on climate, their role in sediment accumulation and their influence on human affairs. This book, which is exhaustively referenced, explores and summarises recent research on where dust storms originate, why dust storms are generated, where dust is transported and deposited, the nature of dust deposits and the changing frequency of dust storms over a range of time-scales.
