World Marine Fog Climatology Based Upon Ship Observations for 1950-2007

The world distribution of fog is presented from ship weather observations over a 58 year period. For the world ocean excluding polar areas, fog is an infrequent event with the median occurrence 0.1 % of the time. Greater fog occurrence is concentrated in three distinct areas: NW Oceans, marginal seas and wind driven upwelling coastal areas. For most areas, the greatest fog is during the summer, over an SST local minimum, and in a thin surface atmospheric layer capped by a stable atmosphere.
