Process Dew Occurrence
Dew forms well on clear and calm evenings. Dew is also well formed when the humidity is high, otherwise when the cloudy sky objects become cool longer because the clouds radiate heat back to the earth. Which when the wind blows, the air takes more time to cool down near the dew point. In areas where the temperature can reach minus below zero degrees Celsius can be found in the form of ice crystals. This dew is called frost or white dew.
