What is Dew-point?

The Dew-point of air is the point where the moisture starts to form drops of water. When the air in the sky is reaching the dew-point, it is starting to rain. The higher the pressure, the less water the air can carry. The colder the air, the less water it can carry. This is why the dew-point drops when the pressure increase and or the temperature decrease.
