visibility

Visibility refers to the distance one can see clearly through the atmosphere, often affected by weather conditions like fog, rain, snow, or pollution. It’s a key factor in navigation and safety, especially for drivers, pilots, and maritime operations. When visibility is high, you can see far ahead; when it's low, your view is limited, making movement and decision-making more challenging. Meteorologists measure visibility using instruments or estimates, and it’s usually expressed in miles or kilometers. Good visibility is essential for safe travel, and understanding its changes helps in planning and responding to weather conditions.
