What happens to the visibility after a cold front passes?

• A. Visibility deteriorates
• B. Visibility improves rapidly
• C. Visibility remains unchanged
• D. Visibility reduces gradually

Answer: (B)

When a cold front moves through, it often brings rain, clouds, and higher humidity that reduce visibility. After the front passes, cooler, drier air moves in, the precipitation ends, and the skies typically clear up quickly. This drying and clearing trend leads to a rapid improvement in visibility, which is why the best choice describes visibility as improving rapidly after a cold front passes. Sometimes there may be lingering showers or fog, but the general pattern is a quick climb in visibility as conditions stabilize.
