Noun
seif (plural seifs)
- A sand dune that elongates parallel to the prevailing wind.
- 1954, Bulletin of the Research Council of Israel, volume 4, page 196:
- Such seifs have a somewhat zig-zag form instead of a fairly straight line.
On the top of seifs small transverse dunelets are very often found, and these may be likened to almost straightened-out barchans. […] On the top of the seif they form a wave-like pattern with a fairly defined "wavelength".
- 1973, Ralph Alger Bagnold, The Physics of Blown Sand and Desert Dunes, page 224:
- Though the actual transition forms suggested in Fig. 76 do exist and have been examined by the author, the above tentative explanation of the growth of a seif dune chain should certainly not be taken as implying that all such chains have originated as barchans.
- 1980, P. Turner, Continental Red Beds, page 80:
- Seifs are longitudinal forms elongated parallel to the prevailing wind direction.
- 2009 February 26, Bruno Andreotti et al., “Giant aeolian dune size determined by the average depth of the atmospheric boundary layer”, in Nature, volume 457, number 7233, , pages 1120–1123:
- Tsoar, H. Dynamic processes acting on a longitudinal (seif) sand dune .
