What is the dew point when it rains?PrecipitationPrecipitation is the process by which water in the atmosphere is returned to the ground though rain, show, dew or other means. This precipitation generally has the effect of raising the relative humidity of the air....
The dew point depends on how much water vapor is present in the air. If the air is very dry with few water molecules, the dew point is low, and surfaces must be much colder than the air for condensation to occur. If the air is very humid with a high concentration of water molecules...
At its most essential, the dew point is the temperature at which air becomes saturated with moisture and can no longer hold all the water vapor suspended, leading to the condensation of excess water vapor into liquid water (dew). It's the tipping point when water vapor leaves the gaseous s...
Dew Point: The dew point temperature is the temperature at which water vapor will condense into water droplets, whether that is cloud droplets, fog, or dew. It is an important measure in meteorology for forecasting and for human comfort, since no more water can be evaporated into the air wh...
Dew point is the temperature to which air must be cooled for water vapor in it to condense into dew or frost. At any temperature there is a maximum amount of water vapor that the air can hold. This maximum amount is called water vapor saturation pressure. Addition of more water vapor res...
The key difference between dew point and freezing point is that dew point is the temperature at which the air becomes saturated with water vapor, whereas the freezing point is the temperature at which a liquid becomes solid.Dew point and freezing point are important analytical parameters. These ...
If the temperature of unsaturated air is decreased, a temperature is reached at which the air becomes saturated with water vapour. This temperature is called the dew point temperature.

Dew Water droplets condensed from the air, usually at night, onto cool surfaces. 2 Guttation Guttation is the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses, and a number of fungi. Guttation is not to be confused with dew, wh...
Depending on temperature, air can hold a fixed amount of water vapor; relative humidity is the ratio of actual vapor in the air to this fixed amount. For example, at a temperature of 68 degrees Fahrenheit (20 degrees Celsius), one cubic meter (35 cubic feet) of air can hold about 18 ...
