WebIf the roadway temperature and dew point temperature are above freezing, liquid water forms on the surface (dew), but if the temperature is below freezing, frost forms … WebFrozen dew forms when air cools to the dew point, and dew forms, and then the air temperature drops below freezing, freezing the dew droplets. Frost is when the dew point is below freezing, so the water vapor in the air changes directly into ice, through deposition. Distinguish among dry haze, wet haze and fog. highboard kiefer massiv

(2) When the dew point rises above freezing, dew, mist, fog, smog, and some clouds form. Condensation can also be characterised by where it occurs, such as at or near the earth’s surface or in free air. Webdew, deposit of waterdrops formed at night by the condensation of water vapour from the air onto the surfaces of objects freely exposed to the sky (see video). It forms on clear nights when the air is calm or, preferably, when the wind is light.
