Isobars on weather maps are lines connecting locations with the same air pressure. Isobaric lines form closed loops, thereby identifying areas of low or high air pressure. For example, if all ...

Hourly weather observations that include sea-level pressure readings are plotted or printed on weather maps that meteorologists can analyze. Isobars are drawn by connecting points having equal ...

A bar is a metric unit of pressure and isobars are lines on a weather map that connect points of equal pressure. Since variations in air pressure drive the winds on Earth, isobars also give ...
