Document title

Two types of longitudinal dune fields and possible mechanisms for their development

Authors(s) and Affiliation(s)



Longitudinal dune fields characteried by nearly uniform interdune spacing are distinguished from longitudinal dune fields characterized by fairly variable interdune spacing and high frequencies of dune coalescence. The empirical and theoretical evidence indicating that the former may be due to helical air currents aligned with the dunes is reviewed. Hypotheses arguing that the latter may arise indirectly from horizontal pressure gradients or bidirectional wind regimes are dicussed An evolutionary timescale is estimated for the formation of desert longitudinal dune fields
