Deserts and Wind

About the lecture

In this module, we think about the distribution and characteristics of deserts, as well as the important aeolian (wind-blown) processes which influence their formation. We focus on: (i) the distribution of deserts, notably in relation to global patterns of aridity; (ii) some of the key landforms on desert surfaces, such as dunes and mountains, and their relative prevalence; (iii) the concept of sediment budget and its importance in understanding desert landscapes; (iv) the roles of sediment size and wind strength in sediment transport processes, and the two main types of transport – suspension and saltation; (v) the influence of desert surface characteristics, such as amount of vegetation, on transport processes.
