On our map, point "P" lies between 3000 feet and 4000 feet contours . Theme: Envo Blog. What role does the Automated Surface Observing Systems (ASOS) play in weather forecasting? You can think of isobars the same way, except that bar means pressure. To get us started on interpreting contour maps, we're first going to revisit our topographic map of Hawaii (right). The 1008 mb isobar passes between cities with pressures of 1009.7 mb at Point B and 1006.8 mb at Point C . First, we must identify the two contours that lie on either side of "P." In some cases the contours that we need are clearly labeled; however, in other instances, you will need to use the contour interval (1,000 feet, in this case) to "count" up or down from a labeled contour. . Where the isobars are close together, windy conditions may be expected. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. Isobars are lines of equal pressure. Isobars can be used to map atmospheric or air pressure in a way that makes it easier to understand. They show how temperature and pressure are changing over space and so help describe the large-scale weather patterns across a region in the map. On weather maps, you may have noticed areas that have a large L or H over a region with lines circling around them. One of the main uses for meteorologists is to identify how the atmosphere is behaving in a given point, this could lead to the identification of high and low-pressure systems. Clearly, we do not have two contours to use or do we? 3. We see an 85 degree isotherm running through Pennsylvania.
