====== AF 201B Unit 13 Orientation Lesson 6 - Wx Theory ======
{{ :courses:201b:ground:201b-wxtheory.pdf |Syllabus}}

The student will become familiar with weather theory (fronts, pressure
systems, fog, etc.).

The student should display an understanding of weather theory (fronts,
pressure systems, fog, etc.).
