In the Takla Makan Desert, the sand dunes near the northern extreme of the Keriya River are shaped by a complex circulation system created when northerly and northwesterly winds meet in the summer.1

This interaction of air currents creates distinct topographical patterns in the sand. Additionally, during the spring, the heating of surface sands triggers ascending currents and strong northeasterly winds, which contribute to the movement of sand and the formation of dust storms. These wind patterns are critical to the desert's geomorphology, as the interaction between wind direction, velocity, and turbulence dictates the resulting dune shapes and sizes.123
