1. Dew point

   The dew point is the temperature to which air must be cooled to become saturated with water vapor, assuming constant air pressure and water content. When cooled below the dew point, moisture capacity is reduced and airborne water vapor will condense to form liquid water known as dew. When this occurs via contact with a colder surface, dew will form on that surface.The dew point is affected by humidity. When there is more moisture in the air, the dew point is higher.When the temperature is below the freezing point of water, the dew point is called the frost point, as frost is formed via deposition rather than condensation. In liquids, the analog to the dew point is the cloud point.

1. dew point

   The dew point is the temperature at which air must be cooled to become saturated with water vapor, causing the moisture in the air to condense and form dew. It is the highest temperature at which dew can form. If the air continues to cool, dew will turn into frost. The dew point can vary based on air pressure and the amount of water vapor present in the air.

1. Dew point

   The dew point is the temperature below which the water vapor in a volume of humid air at a given constant barometric pressure will condense into liquid water at the same rate at which it evaporates. Condensed water is called dew when it forms on a solid surface. The dew point is a water-to-air saturation temperature. The dew point is associated with relative humidity. A high relative humidity indicates that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and that the air is maximally saturated with water. When the dew point remains constant and temperature increases, relative humidity decreases. General aviation pilots use dew-point data to calculate the likelihood of carburetor icing and fog, and to estimate the height of the cloud base. At a given temperature but independent of barometric pressure, the dew point is a consequence of the absolute humidity, the mass of water per unit volume of air. If both the temperature and pressure rise, however, the dew point will rise and the relative humidity will lower accordingly. Reducing the absolute humidity without changing other variables will bring the dew point back down to its initial value. In the same way, increasing the absolute humidity after a temperature drop brings the dew point back down to its initial level. If the temperature rises in conditions of constant pressure, then the dew point will remain constant but the relative humidity will drop. For this reason, a constant relative humidity with different temperatures implies that when it's hotter, a higher fraction of the air is water vapor than when it's cooler.

1. Gregg Berhalter:

   When we go down to those countries and it’s 90 degrees and 90% dew point and it’s unbearable humidity and guys are getting dehydrated and cramping up and getting heat exhaustion, that’s the nature of our competition.
