When does it get foggy in Guizhou?

Winter. Because the influence of cold air is more frequent in winter, winter is also a period of high incidence of fog in Guizhou. If combined with special road terrain conditions, heavy fog or dense fog often occurs. Fog in Guizhou mainly forms in three ways: first, the most common "radiation fog", which mostly appears in autumn and winter in clear weather conditions with clear morning breezes and abundant water vapor near the ground; second, the "front" that appears after cold air moves south "Fog" dissipates after the cold air blows over; the third is fog caused by special terrain. In mountainous areas, the humid air at the bottom of the valley condenses water vapor during the climb, thus forming fog on the top of the mountain or halfway up the mountain.
