Isobar

An isobar is a line on a weather map that connects points sharing the same atmospheric pressure at a specific time. These lines help meteorologists visualize how air pressure varies across regions, indicating high-pressure systems (generally associated with clear weather) or low-pressure systems (often linked to storms or precipitation). By analyzing isobars, weather patterns, wind flow, and potential weather changes can be better understood. They are essential tools in weather forecasting, providing a visual representation that simplifies the complex movement of air masses in the atmosphere.
