Development of open ocean fog forecasting regions

Fog and low visibilities have long been considered serious hazards to navigation at sea. Neither is particularly easy to forecast. Many approaches can be taken to attack the problem. One possible approach to developing forecast equations is through application of statistical techniques. As a part of that approach, regions have been developed which are homogeneous with respect to synoptic weather and oceanographic patterns, fog occurrence, and observation density. This Technical Note describes the statistics which went into the development of the regions, the selection of the appropriate seasons for the regions, and the regions themselves.The regions cover the North Atlantic and North Pacific Oceans from 25 deg North to 70 deg North.
