ISOBARS- Certain weather maps allow us to view High and Low pressure systems that control the weather. An isobar is a line connecting locations of equal barometric pressure. Isobar maps show where pressures are relatively high and low, and show us where pressure changes are gradual or dramatic over a distance.

Station ModelStation Model All over the United States, hundreds of

weather observations are taken several times during the day.

Meteorologists need a way to get all of this detailed information into the smallest area possible on a weather map, so that several stations can be plotted for the same observation time on the same map, thus giving a ‘big picture’ of what the weather is doing at a snapshot in time.

Thus, the need for the station model.
