Fog dew point spread
WebDec 14, 2016 · The dew point is the temperature at which condensation (a cloud) forms. If the dew point is the same as the temperature on the ground, then there will be fog. The temperature usually decreases as the altitude increases. This is called the lapse rate. WebIn this example, the reported dew point temperature is 58 degrees. Dew points indicate the amount moisture in the air. The higher the dew points, the higher the moisture content of the air at a given temperature. Dew point temperature is defined as the temperature to which the air would have to cool (at constant pressure and constant water ...

Not necessarily. Season, time of day, terrain, wind, etc. all have an effect on the temperature/dew point relationship.
WebThe 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 as fog or precipitation.
