Atmospheric pressure is the weight of air pressing down on Earth’s surface. It is higher at sea level and lower in mountains. It affects weather patterns and human comfort. Barometers measure this pressure, usually in millibars. Low pressure often signals storms or rain.

Atmospheric pressure is the force exerted by the weight of air above and around us. It varies with height—being highest at sea level and decreasing with altitude. It influences weather systems; for example, low pressure can lead to storms or rainfall. People often feel changes in pressure before bad weather. It is measured in millibars using barometers. Understanding atmospheric pressure is essential for weather forecasting, flying and even human health, especially in high-altitude regions where oxygen is low.
