Forms of Condensation

P.146 Table 5-3

Dew is usually formed on cool, clear, calm nights ;

Frost‘s formation is similar to dew but they also need a temperature below freezing (0 °C)

1. Dew
   • Lowering temperature to dew point near the surface
   • prefer clear skies and no wind, and usually formed during the early morning
   • Diabatic process 
2. Frost
   • Lowering temperature to frost point, of which temperature is below 0°C
   • Diabatic process
3. Frozen dew
   • formation dew and then cool down to a temperature below 0°C
   • Diabatic process
4. Fog
   • Radiation fog
     • Diabatic process
   • Advection fog
     • Diabatic process
   • Upslope fog
     • Adiabatic process
   • Precipitation fog
     • Adiabatic process
   • Steam fog
     • Adiabatic process
5. Clouds
   • lifting of air
   • Adiabatic process
