Washington DC: U. S. Navy, Bureau of Aeronautics, c1943. Presumed First Edition, First printing. Wraps. Two-hole punched. 32 pages, plus covers. Illustrated front cover. Illustrations. Glossary. The booklet was designed to point out some of the flight problems involved in negotiating the type of weather conditions that are associated with the warm front. This booklet will inform the aviation cadet about the characteristics of the warm front. A warm front is the leading edge of a warm air mass that is replacing a colder air mass. A warm front is depicted by a red line with half-moons pointing the direction of its motion. Like cold fronts, warm fronts also extend from the center of low-pressure areas, but nearly always on their east side. Warm fronts move slowly, typically 10 to 25 miles per hour. Generally, prior to the passage of a warm front, cirriform or stratiform clouds, along with fog, can be expected to form along the frontal boundary. Light to moderate precipitation is probable, usually in the form of rain, sleet, snow, or drizzle, accentuated by poor visibility. More
