What is the station model and weather symbols?
In meteorology, station models are symbolic illustrations showing the weather occurring at a given reporting station. Elements in the plot show the key weather elements, including temperature, dew point, wind, cloud cover, air pressure, pressure tendency, and precipitation.
What symbols are used in a station model?
In the center of the station model is a symbol or picture that represents two things: the cloud cover and the wind speed. The central circle represents the cloud cover. A black circle means the sky is completely overcast and cloudy, and a white or empty circle means that the sky is completely clear of clouds.

The large letters (Blue H’s and red L’s) on weather maps indicate high- and low-pressure centers. They mark where the air pressure is highest and lowest relative to the surrounding air and are often labeled with a three- or four-digit pressure reading in millibars.
How do you read a weather plot?
- A weather symbol is plotted if at the time of observation, there is either precipitation occurring or a condition causing reduced visibility.

What do the red and blue lines mean on a weather map?
On a weather map, a warm front is usually drawn using a solid red line with half circles pointing in the direction of the cold air that will be replaced. On a weather map, a cold front is usually drawn using a solid blue line with triangles pointing in the direction of the warm air that will be replaced.
