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 (like the U.S.), and they can tell us how intense the system may be.
Wind Direction and Isobars surface maps. Winds flow roughly parallel to the isobars, as depicted in the schematic below. This relationship is observed on real surface maps. In the example below, surface observations and isobars (yellow contours) have been plotted. Reports of wind direction from Nebraska into Minnesota, show that the observed wind direction is nearly parallel to the isobars.
