Which mechanism causes star dune formation in hyper-arid environments?

💡 Explanation

Star dunes form because bidirectional winds generate transverse ridges, and multidirectional shifts cause sand to accumulate vertically rather than migrating linearly. Therefore, omnidirectional wind regime confluence is responsible, rather than unidirectional or stabilizing processes influencing other dune types.
