Evaluating the Impacts of Climate fluctuations on wind processes (Case study: Abshirin ecosystem)

Farhad Hasani Dorabad; Naser Mashhadi; AmirReza Keshtkar

Volume 76, Issue 1 , June 2023, , Pages 77-101


  The desert environment is aeolian, being dominated by the wind. The dynamics of wind erosion are driven by both natural processes, including climate and its fluctuations, and human activity. Separating the climatic and anthropogenic causes of wind erosion can improve the understanding of its driving ...  Read More
