8.4.1 Tell me What are weather maps?
Weather maps or ‘synoptic charts’ appear every day in newspapers and during the television news. We may see them as digital images on our phones as weather apps. Weather maps use lines and symbols to show areas of low and high pressure and weather events such as cyclones, rainfall, warm and cold fronts. The lines on a weather map are called ‘isobars’. Isobars join places with the same atmospheric pressure. The numbers on the isobars represent differences in atmospheric pressure, which is the weight of the air. This varies from place to place, depending on the air temperature. Meteorologists use sensitive instruments called ‘barometers’ to measure atmospheric pressure.
