The dew point of a given body of air is the temperature to which it must be cooled to become saturated with water vapor. This temperature depends on the pressure and water content of the air. When the air is cooled below the dew point, its moisture capacity is reduced and airborne water vapor will condense to form liquid water known as dew. [1]

The temperature at which frost will form is called the dew point, and depends on the humidity of the air. [1] When the temperature of the air drops below its dew point, excess water vapor is forced out of solution, resulting in a phase change directly from water vapor (a gas) to ice (a solid).
The dew point is a saturation point. When the dew point temperature falls below freezing it is called the frost point, as the water vapor no longer creates dew but instead creates frost or hoarfrost by deposition. [17] The dew point is associated with relative humidity. A high relative humidity indicates that the dew point is closer to the ...
The present weather symbol depicts the current weather which normally is obstructing the visibility at the time of observation. The visibility itself is shown as a number, in statute miles in the United States and meters elsewhere, describing how far the observer can see at that time. This number is located to the left of the present weather ...
A dry line (also called a dew point line, or Marfa front, after Marfa, Texas) [1] is a line across a continent that separates moist air and dry air. One of the most prominent examples of such a separation occurs in central North America , especially Texas, Oklahoma, and Kansas, where the moist air from the Gulf of Mexico meets dry air from the ...
Especially in meteorology they are used to analyze the actual state of the atmosphere derived from the measurements of radiosondes, usually obtained with weather balloons. In such diagrams, temperature and humidity values (represented by the dew point ) are displayed with respect to pressure .
