On a weather map, isobars closely spaced indicate what condition?

Explanation:
Isobars are lines of equal surface pressure. When these lines are closely spaced, the pressure changes a lot over a short distance, creating a strong pressure gradient force that drives faster winds near the surface. So closely spaced isobars indicate strong winds. If the isobars are far apart, the gradient is weak and winds are lighter. Extreme rainfall isn’t determined by how close isobars are; it depends more on moisture and lifting processes.
