Station model
A station model is a symbolic illustration showing the weather occurring at a given reporting station. Meteorologists created the station model to find a number of weather elements in a small space on weather maps. Maps filled with dense allows users to analyze patterns in air pressure, temperature, wind, cloud cover, and precipitation.〔CoCoRAHS (2005).

Station model plots use an internationally-accepted coding convention that has changed little since August 1, 1941. Elements in the plot show the key weather elements, including temperature, dew point, wind, cloud cover, air pressure, pressure tendency, and precipitation.〔National Weather Service (2003).

==Measurement location and units==
Weather maps primarily use the station model to show surface weather conditions, but the model can also show the weather aloft as reported by a weather balloon's radiosonde or a pilot's report.
Station model plots use a mixture of metric and Imperial units depending on the map's location and what is being shown. Surface maps in the United States primarily use Imperial units, such as inches, degrees Fahrenheit, and knots. Most of the world, however, uses metric measurements for everything but wind speed, which is shown in knots.
