Define isobar and isotherm. Interpret weather maps using isobars to locate high and low pressure systems, . Meteorology is the study of the atmosphere and its phenomena. Meteorologists are scientists who study the atmosphere and its phenomena. Many also interpret weather maps and make forecasts.
Weather maps show isobars and isotherms.
Isobars are lines of equal air pressure. The isobar lines are labeled with a number representing the air pressure in hectopascals. In high pressure systems , the air pressure increases towards the cente r. When the isobars are closely spaced, strong winds are likely to be present associated with low pressure systems. When the isobars are far apart, relative calm prevails which is usually associated with high pressure systems.
