Station Model

 Television weather reports represent weather conditions with smiling suns, rainy clouds and flashing bolts of lightning. In studying the weather we need to know where it is raining and where it is sunny, the wind speed and direction, humidity, visibility, pressure and temperature. To understand the weather we need to know how these meteorological variables are changing and how they relate to one another. To understand these relationships it is best to represent weather variables in a simple graph. Smiling suns do not contain enough information about the weather. On the other hand too many numbers drawn on a single map presents a confusing picture. Weather conditions observed at a city or town are best represented on a map using the station model.
