摘要
Pattern formation in sand dunes due to localized strong winds is investigated taking a downburst as an example. Extending the phenomenological model proposed by Nishimori et al. and taking into account the characteristic of powders, we calculate numerically the temporal evolution of sand patterns without using the hydrodynamic equations. We discuss the relation between the velocity distribution of a downburst and obtained patters qualitatively.
