Isobars are lines of constant or equal pressure on a weather map. They can be used to find areas of low or high pressure over a broad area (like the U.S.), and they can tell us how intense the system may be.
The circular lines you see on the chart are isobars-joining areas of the same barometric pressure. The pressure pattern is important because we can use it to tell us where the wind is coming from and how strong it is.It also shows areas of high and low pressure.he word 'synoptic' simply means a summary of the current situation. In weather terms this means the pressure pattern, fronts, wind direction and speed and how they will change and evolve over the coming few days.
