The composition of Danniang sand dunes mainly comes from

Danniang sand dunes were formed by the accumulation of wind power. Every winter and spring, the climate in this area was dry, and the wind was strong. In addition, the vegetation was thin, so the wind was less blocked by the river surface, forming a vortex updraft. These air currents carried sand grains from the sandbars and floodplains, which were blocked by the mountainous terrain by the river. The wind speed slowed down, and the sand grains piled up on the hillside, forming Danniang sand dunes over time.

Danniang's sand dunes were formed by the accumulation of wind power. Every winter and spring (mainly from October to March of the next year), the climate in this area was dry, and the wind was strong. In addition, the vegetation was thin, and the wind was less blocked by the river surface, thus forming a vortex updraft. The airflow carried sand grains on the sandbars and floodplains. It was blocked by the mountainous terrain along the river, and the wind speed slowed down. The sand grains piled up on the hillside and accumulated over time to form sand dunes.

However, there was no clear information about the direction of the wind. Thus, it was impossible to determine the dominant wind direction of Danniang's sand dune.

Danniang Sand Dune was located in Danniang Township, Milin County, Xizang, 90 kilometers away from the confluence of the two rivers. It was the largest sand dune in the middle of the Yarlung Zangbo River. The sand dunes were formed mainly because the sand grains from the nearby sandbars and floodplains were piled up on the slopes by the wind, forming the current sand dunes over time. Danniang Sand Dune was also known as the Buddha Palm Sand Dune because it was shaped like a Buddha's palm. The climate in this area is diverse, including tropical, sub-tropical, temperate-zone and frigid climate, and the annual rainfall is about 650 millimeters. The best season to view Danniang sand dunes was winter and spring. At this time, the water flow of the Yarlung Zangbo River slowed down, the riverbed was exposed, and the wind was strong, making the sand dunes more obvious.
