What is Atmospheric Pressure? A Comprehensive Guide

Atmospheric pressure, often referred to as air pressure, is the force exerted by the weight of the air above us. It plays a crucial role in weather patterns, aviation, and even human health.

Understanding Atmospheric Pressure

To define atmospheric pressure, it is measured in units like Pascals or atmospheres (atm). Standard atmospheric pressure at sea level is approximately 1013.25 hPa.

How It Affects Weather

Changes in atmospheric pressure indicate upcoming weather conditions. High pressure usually brings clear skies, while low pressure often results in storms or rain.

Common Questions Answered

Why does atmospheric pressure decrease with altitude?
As you go higher, there is less air above, reducing the pressure exerted.

How is it measured?
Barometers are the primary instruments used for measuring atmospheric pressure accurately.
