Dew point below freezing

WebCondensation can occur when the dew point is below freezing or 0° C, and it can also occur when the dew point is above freezing. The types of condensation can be divided into two groups in this way: (1) When the dew point falls below freezing, frost, snow, and certain clouds occur. (2) When the dew point rises above freezing, dew, mist, fog ... WebWhen air cools to its dew point through contact with a surface that is colder than the air, water will condense on the surface.
