What do you mean by blowing snow?

Heavy snow;

Heavy snowfall will occur a few hours after snowfall in mountainous areas. It is a strong wind formed by strong boosting airflow, which can blow up the snow on the ridge or windward slope and cross the mountain, and the blowing height can reach more than 30 meters. In the form of suspended flying, snow particles pour down from hillsides, troughs and valleys, covering the sky, just like fog permeating Shan Ye. When the snow blows high, the visibility is very small and the harm is serious, but the duration is short, mainly in mountainous areas.
