Why is a frost more likely if the dew point is above freezing?
• Temperatures remained below freezing during the afternoon. • The snow may crust at night, due to outward radiation, even thought the air temperature remains well above freezing point. • Temperatures had, for several days, been near 00F at night, and it was well below freezing now.
The freezing level, or 0 °C (zero-degree) isotherm, represents the altitude in which the temperature is at 0 °C (the freezing point of water) in a free atmosphere (i.e. allowing reflection of the sun by snow, icing conditions, etc.).
The freezing level is the elevation at which the air temperature is 0 degrees Celsius, 32 degrees Fahrenheit, or 273 degrees Kelvin. At this temperature, water freezes, including particles of moisture in the air*.
Apr 21, 2015 · The higher the dew point is above freezing, then freezing temperatures are less likely. If the dew point is below freezing, then a frost becomes more likely. Dry air heats and cools much more quickly than humid air.
Sleet and freezing rain occur by a similar process, but are different forms of precipitation. Sleet occurs when snowflakes melt into a raindrop in a wedge of warm air well above the ground and...

Apr 28, 2016 · Ice, at least at atmospheric pressure, cannot form above the melting point of water (0 Celsius). The phenomenon of water freezing on objects like the ground, parked cars, motorbikes etc, is due to thermal inertia. On a long, cold spell these objects will cool down to below 0 Celsius.
Freezing or frost occurs when the air temperature falls below the freezing point of water (0 °C, 32 °F, 273 K). This is usually measured at the height of 1.2 metres above the ground surface.
