In the middle of March 2021, a persistent dust weather broke out in central East Asia including most parts of northern China, which aroused people's high attention to the dust source area and the benefit of the ecological construction project. Using high precision and large range of meteorological data, this paper calculated the dust driving conditions on the ground and the sand transport conditions during the strong wind process, and estimated the dust lift amounts at different hours. Then, the dust contribution rates of Mongolia and northern China were obtained for the days of 14th and 15th. The results show that, compared with the past ten years, northern China is not prone to emit dust, while desert areas in central and eastern Mongolia tend to rise more dust due to significant temperature increase and decreased precipitation. It shows that 75% of the dust in the strong dust storm in Beijing on March 15 was raised on the 14th in Mongolia, while 84% of the dust in the followed larger storm on the 16th and 17th was raised from North and Northwest China on the 15th. The total dust amounts inside and outside the border are basically the same.

Key words: dust storm, Central East Asia, dust lift amount, climate change
