The researchers studied wind patterns in the Dunhuang Gobi desert from 2002 to 2008. They found that the prevailing wind directions are east and west, with wind speeds following a specific pattern. During the day, the wind blows from the east, while at night it comes from the south. Wind speeds are higher during the day than at night. In summer, the wind tends to come from the northeast, while in winter it comes from the south. The wind speed varies throughout the year, with the highest speeds in April and the lowest in January. Overall, the wind direction remains consistent over the years, while wind speed shows a slight decrease over time.
