Definition

Circular to elliptical, relatively flat mounds often without external slip faces.

Synonyms

Morphometry

On Mars, they are 40–100 m across and <30 m high with 100–1,000 m spacing (De Hon 2006).

Formation

They form where dune height is inhibited by unobstructed strong winds. Strong unidirectional winds retard normal upward growth of dune crests, leading to the formation of dome dunes. Alternatively, they may form when wind velocities are low (Pye and Tsoar 1990 and references therein). Dome dunes may transform into other dune forms. Computer modeling (Parteli et al. 2009) suggests that dome dunes may form if the wind oscillates between two prevailing directions with a period shorter than 0.01 % of the dune’s turnover time, which is the time needed for the dune to cover a distance equal to its own size.

Domes may also be dunes smaller than the critical size for a barchan development where slip faces and horns are not able to evolve (Parteli 2007).
