WebDew forms when the air cools to the dew point. Frozen 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.

The dew point is the temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative humidity (RH) of 100%. At this point the air cannot hold more water in the gas form. If the air were to be cooled even more, water vapor would have to come out of the atmosphere in the liquid form, usually ... department of transport wait timesWebFrost forms is the same way as dew except it occurs when the dewpoint is below freezing.
