What does a wider spacing of iso bars around low pressure indicate?

Wider spacing of isobars around a low-pressure area signifies a weak pressure gradient. The pressure gradient is the difference in atmospheric pressure between two points over a specific distance; when the isobars are farther apart, this indicates that the change in pressure over that distance is gradual.

In atmospheric terms, a weak pressure gradient often leads to lighter winds, as there is less difference in pressure between adjacent areas. Recognizing this concept is important for understanding weather patterns and predicting wind behavior. When isobars are closely spaced, it indicates a strong pressure gradient, leading to stronger winds.

Therefore, the correct interpretation of wider spacings between isobars is that they suggest a less intense variation in pressure, corroborating the identification of a weak pressure gradient.
