Weather Station Symbols Chart - Meteorological Symbol Guide by EPA #1803794 (License: Personal Use)

The chart, published by the U.S. Department of Environmental Protection, systematically organizes meteorological symbols across categories including cloud coverage (e.g., 1/10 to 9/10), wind speed (calm to 50 knots), front types (warm, cold, stationary, occluded), cloud types by elevation, and weather conditions like rain, snow, thunderstorms, and hail. It also includes barometric tendency indicators, air pressure markers (H/L), and miscellaneous sky cover phenomena such as fog, haze, and dust/sand.

Used primarily by meteorologists, students, and weather enthusiasts to read and interpret surface weather maps; supports educational content, forecasting training, and operational weather analysis where symbol literacy is critical.
