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.
Weather Fronts and Isobars The boundary between a system of warm and cold air is known as a âfrontâ which coincides with changes in air pressure. Weather maps (surface chart) and forecasts usually show areas of low (red âLâ) and high pressure (blue âHâ) as well as weather fronts. Isobars, lines of equal pressure, when drawn on such a map, give a contour map showing areas of high and low pressure. Range of Barometric Pressure on Earth. Refer to Barometer Calibration
