A mathematical model for aeolian megaripples on Mars

The recent mathematical model for megaripples formation proposed by Yizhaq [Physica A 338 (2004) 211] is used to explain the huge megaripples formation observed on Mars. The model also predicts a few linearly unstable modes which correspond to megaripples with different wavelengths at the same wind condition as seen in some places on Mars. Studying these aeolian bedforms can provide information about the past and present climatic conditions on Mars.
