“A dune that tends to develop unusual height but migrates only a limited distance because seasonal shifts in direction of the dominant wind cause it to move alternately in nearly opposite directions” (Jackson 1997, p. 545).


Reversing dunes are intermediate in character between star and transverse dunes. They are similar to transverse dunes but have a secondary slip face which develops periodically and is oriented in an opposite direction from that of the primary slip face (McKee 1979).


Sigmoidal dune. S-shaped or straight, triangular (Tsoar 2001), steep-sided, sharp-crested dune which is formed in response to alternating and opposing winds of roughly equal velocities (Holm 1957; Stone 1967; Edgell 2006) (Fig. 1).
