A strong Mongolia Cyclone will form gradually, according to data analysis. Since March 26, with the cyclone and the accompanied cold air, a large-scale SDS will occur in the southern part of Mongolia from the west to the east. As the cyclone moves eastward, on March 27, the scope of SDS will be expanded and the intensity will also be enhanced significantly. Moreover, when the cyclone shifts further south, the downstream areas, such as China and the Republic of Korea, will encounter the SDS brought by the cyclone. So please pay attention to the subsequent SDS forecast as well as the necessary mitigation and prevention  measures(RSMC-ASDF BEIJING reported).
