isobars

Isobars are lines on weather maps that connect points experiencing the same atmospheric pressure at a given time. They help visualize how pressure varies across an area, indicating high-pressure systems (anticyclones) and low-pressure systems (cyclones). Closely spaced isobars suggest strong winds, while widely spaced ones indicate calmer conditions. Meteorologists use isobars to understand weather patterns and predict changes, such as storms or clear skies. Essentially, they’re tools that make the invisible force of air pressure visible, helping us interpret and anticipate local and global weather behavior.
