Atmospheric Pressure Definition: What It Is and How It Works

Atmospheric pressure is the force exerted by the weight of air in Earth’s atmosphere. It affects weather patterns, human health, and various technologies. Understanding this concept is essential in fields like meteorology, aviation, and engineering.

Key Components of Atmospheric Pressure

The standard atmospheric pressure at sea level is 1013.25 millibars or 29.92 inches of mercury. It decreases with altitude due to thinner air. Instruments like barometers measure this pressure, helping predict weather changes.

How Atmospheric Pressure Works

Air molecules have weight and collide with surfaces, creating pressure. Variations occur due to temperature and altitude shifts. High pressure often brings clear skies, while low pressure indicates storms or rain.
