Question 1266Navigation General

The correct answer is C) visibility will improve rapidly. After the passage of a cold front, the air mass behind the front is typically drier and less humid compared to the air mass ahead of the front. This drier air reduces the amount of water vapor in the atmosphere, leading to a decrease in haze and improved visibility. The decrease in moisture and cloud cover associated with the passage of a cold front allows for better visibility, which usually improves rapidly as the front moves through the area. The other options are incorrect because: A) Visibility does change after the passage of a cold front, typically improving. B) Visibility becomes better, not poorer, after the cold front passes. D) Visibility improves rapidly, not just slightly, due to the drier air mass behind the front.
