    Abstract:
    A novel small wavelength instability occurs in experiments for vertically shaken (z = a cos(ωt)) sand, for small particle diameters d and when gas effects are important. At onset, the energy (aω)2/gd is proportional to a/d, as previously found for traveling waves. The instability begins as a surface perturbation with wavelength λ0 ∼ 6 mm; subsequently λ grows exponentially in time. © 1997 Published by Elsevier Science B.V.
