Meeting of warm and cold ocean currents

Ocean currents are the horizontal continuous flow of a mass of water from one place to another. They are of 2 types – warm and cold ocean current. The meeting of cold and warm currents results into a meeting of the overlying warm air and cold air. The warm air meeting the colder air will cool the warm air below its dew point resulting in the formation of a thick fog. This meeting point of ocean currents also provides a rich ground for fishing due to the abundant presence of plankton.
