The city of Hohhot in North China’s Inner Mongolia autonomous region is coated in rime, the frosty filigree of ice, on Jan 9. It was the first rime the city had received in 2020. Rime is a rare natural phenomenon in winter, when oversaturated water vapor condenses in the air. It is caused by the rapid freezing of supercooled water droplets on impact with an object. Hohhot city has become a land of rime because of its extreme range of temperature, separating day and night. [Photo/Xinhua]
