An advection freeze occurs when cooling by advection predominates, and a radiation freeze occurs when radiational heat loss is the predominant form of cooling. Radiation freezes occur mostly on clear, calm nights after cold air has moved into the region. The primary mechanism is loss of heat into space during the night. ... During radiation freezes, layers of cold air are formed with the coldest air normally found near the radiating surface. 2, record 1, English, - radiation%20frost
