Web11 de ago. de 2024 · The dew point is the temperature to which the air must be cooled in order for it to become saturated. It provides a measure of the actual amount of water vapor in the air – so the higher the dew point, the more moisture in the air. WebAs the air temperature is cooled to the dew point, the relative humidity increases and reaches 100% when the two temperatures coincide. The best way to understand the dew point notion is to visualise how dew is formed on a clear fall morning, for example. Dew occurs as a result of the air gradually cooling overnight. Web22 de out. de 2024 · What is a Dew Point? The dew point is the temperature at which the air, with no change in pressure, must be cooled to become fully saturated. At this temperature, the moisture will condense into dew. It is important for predicting the formation of dew, frost, fog, and even the minimum temperature.
