Detailed explanation-1: -Depositional frost is also known as white frost or hoar frost. It occurs when the dewpoint (now called the frost point) is below freezing. When this frost forms the water vapor goes directly to the solid state.
Detailed explanation-2: -Snow forms when the atmospheric temperature is at or below freezing (0°C or 32°F). If the ground temperature is at or below freezing, the snow will reach the ground. However, the snow can still reach the ground when the ground temperature is above freezing if the conditions are just right.
Detailed explanation-3: -At temperatures below the dew point, the rate of condensation will be greater than that of evaporation, forming more liquid water. The condensed water is called dew when it forms on a solid surface, or frost if it freezes.
Detailed explanation-4: -This is the key to the rapid snow melt you witness when dew points soar into the 40s and 50s. The dew point is the temperature that air needs to achieve in order to condense. If you have a temp of 40F and a dew point of 40F, the air is said to be saturated and you’re going to be seeing some fog, mist, rain, or snow.
