A line on a weather map joining places with the same air pressure

An isobar is defined as a line on a weather map that connects points of equal atmospheric pressure. This meteorological tool is crucial for visualizing the distribution of pressure over a geographic area, which helps in analyzing weather patterns and predicting meteorological conditions. Isobars can indicate areas of high and low pressure; when isobars are close together, they suggest a steep pressure gradient, often associated with strong winds. Conversely, widely spaced isobars indicate a gentle pressure gradient and lighter winds. This understanding of isobars is essential in fields such as meteorology and atmospheric science, aiding in the interpretation of weather data and forecasts.
