  1. Fog

    Fog is a collection of liquid water droplets or ice crystals suspended in the air at or near the Earth's surface. While fog is a type of stratus cloud, the term "fog" is typically distinguished from the more generic term "cloud" in that fog is low-lying, and the moisture in the fog is often generated locally. Fog is distinguished from mist only by its density, as expressed in the resulting decrease in visibility: Fog reduces visibility to less than 1 km, whereas mist reduces visibility to no less than 1 km. For aviation purposes in the UK, a visibility of less than 5 km but greater than 999 m is considered to be mist if the relative humidity is 70% or greater – below 70% haze is reported. The foggiest place in the world is the Grand Banks off the island of Newfoundland, the meeting place of the cold Labrador Current from the north and the much warmer Gulf Stream from the south. Some of the foggiest land areas in the world include Argentia, Newfoundland and Point Reyes, California, each with over 200 foggy days per year. Even in generally warmer southern Europe, thick fog and localized fog is often found in lowlands and valleys, such as the lower part of the Po Valley and the Arno and Tiber valleys in Italy or Ebro Valley in northeastern Spain, as well as on the Swiss plateau, especially in the Seeland area, in late autumn and winter. Other notably foggy areas include Hamilton, New Zealand, coastal Chile, coastal Namibia, and the Severnaya Zemlya islands.

Dictionary of Nautical Terms

  1. fog

    A mist at sea, consisting of the grosser vapours floating in the air near the surface of the sea. The fog of the great bank of Newfoundland is caused by the near proximity of warm and cold waters. The air over the Gulf Stream, being warmer than that over the banks of Newfoundland, is capable of keeping much more moisture in invisible suspension; and when this air comes in contact with that above the cold water, it parts with some of its moisture, or rather holds it in visible suspension. There are also dry fogs, which are dust held in suspension, as the so-called African dust, which often partially obscures the sun, and reddens the sails of ships as they pass through the north-east trades.
