We demonstrate a previously unexplored range of patterns in vibrated non-cohesive granular systems. Some of the patterns we observe are ubiquitous on the surface of Earth and Mars. Surprisingly however, we observe a swirling motion —called here as ‘’Granular Cyclones’’— in the granular bed in a narrow range of frequencies. We report features and properties of this swirling granular motion and other topological patterns in this simple yet fascinating experimental system.
