Wind and the Navigator, Wind Theory - USAF Training Film (1957)

This film explains what causes wind, how it acts, and how the various driving forces in the atmosphere set up winds that behave according to well established laws. Animation is used to explain pressure gradient force, Coriolis force, geostrophic wind, gradient wind, friction level, wind contours (isobars), and constant pressure charts. This film is a natural complement to both the private pilot and instrument ground school courses.
