Part of a series of color, animated aerology films produced for the U.S. Navy in World War II, “The Theory of Fog Formation” (1943) was made for trainee pilots, with an aim to improve their understanding of fog and safe flight through it. After outlining the theory of fog formation, the film overviews various types of fog and how each one impacts air travel. It also reviews the combined effects of air temperature and wind. The film concludes with an anecdote about a bomber plane mission.

The other films in this seven film series discuss such subjects as ice formation on aircraft, warm and cold fronts and the serious weather associated with each, cloud formations, and

flight planning through and around weather conditions.
