The frequency of sand-dust weather（SDW）decreased and the intensity weakened in northern China during 1961-2020，while the SDW frequency（SDWF）of spring sharply increased in 2021 and 2023，which prompted widespread concern. As we know，the changes of spring general atmospheric circulation and surface condition of sand-dust source region are the main factors impacting the variation of SDW. Due to the weakening of mid-high latitude of Eurasia continent under global warming，there has been a notable reduction in the transportation. Additionally，owing to China’s efforts in preventing and controlling desertification during recent decades，sand-dust is less easily blown into the sky from sand-dust source region. Both factors have contributed to the notable decrease of SDWF in northern China. While，at the same time，the significantly warmer conditions over mid Asia have exacerbated the drought in southern Mongolia. This has deteriorated surface conditions and facilitated the lifting of sand-dust into the sky，which was then carried to northern China and other part of East Asia through atmospheric circulation. The occurrence of sand-dust weather in northern China is projected to decrease in the future as a result of global warming. However，it is anticipated that the dust concentration will increase in the arid and semi-arid areas of Central Asia，West Asia，and northern East Asia. In order to effectively cope with the risk of sandstorms exacerbated by climate change，China still needs to consolidate the achievements of desertification prevention and control，build a stronger ecological security barrier in the north. Moreover，it is imperative to continue to strengthen international cooperation in desertification prevention and control. Additionally，there is a need to improve the construction of the monitoring station network in the sand-source regions，as well as strengthen scientific research efforts to enhance the prediction capabilities and early warning systems for sand-dust events.
