What is a cold air funnel? A cold air funnel is a high based, weak circulation that occurs in a cool air mass. It develops well above the earth’s surface. Since it is high based and weak, they rarely impact the earth’s surface, although they can look threatening.
Unlike typical tornadoes, cold air funnels develop in a shallow cool air mass and often behind a cold frontal passage.
