Which fog forms over warm water in very cold air?

  • A.Advection fog, which forms instead where warm moist air moves across a surface that is colder than its dew point
  • B.Radiation fog
  • C.Frontal fog, which forms where precipitation falling from warm air aloft saturates the colder air beneath it
  • D.Steam fog

Answer: D

Cold air flowing over much warmer water is rapidly moistened and mixed, and because the saturation curve is convex the mixture becomes supersaturated and fog forms. Arctic sea smoke is the extreme case. Advection fog forms by the opposite arrangement, warm air over a cold surface, which is a useful contrast to draw explicitly.
