What happens to winds when isobars are close together?

• A. Winds are weaker
• B. Winds are calm
• C. Winds are moderate
• D. Winds are stronger

Answer: (D)

When isobars are close together on a weather map, it indicates a steep pressure gradient between high and low pressure areas. This steep gradient results in stronger winds. The closer the isobars are, the more rapid the change in pressure over a given distance is, which leads to increased wind speeds. Meteorologically, this phenomenon reflects the fundamental relationship between pressure differences and wind behavior; the greater the pressure difference, the stronger the resulting winds. Therefore, when isobars are tightly packed, it signifies that the atmospheric conditions are conducive to stronger wind flow, leading to gusty conditions.
