The effects of windblown sand on the deterioration of mural paintings in cave 285, in Mogao caves, Dunhuang

Windblown sand, driven by high-velocity winds, is a significant factor in the deterioration of mural paintings on the east wall of Cave 285 in the UNESCO-listed Mogao Caves. Despite being less exposed to moisture and solar radiation compared to other walls, the east wall exhibits notable damage, including detachment, flaking, and fading, attributed to sand adhesion and collision. This study highlights the dual impact of wind velocity on both the physical structure and artistic integrity of the murals, offering critical insights for conservation efforts in arid environments.
