Isobars are lines of constant or equal pressure on a
weather map. They can be used to find areas of low or
high pressure over a broad area, and they can tell us
how intense the system may be. On weather maps, you
may have noticed areas that have a large L or H over a
region with lines circling around them. The L stands for
low pressure and H stands for high pressure. The lines
circling them are isobars.
