Precipitation in the form of moisture that
collects on the ground. It forms after the
temperature of the ground has fallen below
the dew point of the air in contact with the
ground. As the temperature falls during the
night, the air and its water vapour become
chilled, and condensation takes place on the
cooled surfaces. When moisture begins to
form, the surrounding air is said to have
reached its dew point. If the temperature
falls below freezing point during the night,
the dew will freeze, or if the temperature is
low and the dew point is below freezing
point, the water vapour condenses directly
into ice; in both cases hoar frost is formed.
