Definition: Fog which forms in the lower part of a relatively moist and warm air mass as it moves over a relatively cooler water surface. This process cools the water vapour to such an extent that it condenses into the suspended water droplets that create the fog. It reduces visibility to less than one-half (1/2) nautical miles. (See also advection fog).  ECCCanada
