### What Is the Range of Barometric Pressure? | Sciencing

In an area of high pressure, the air is denser than the air surrounding it. Winds blow air out of a high-pressure area, causing it to sink. As air slowly descends, its temperature rises. The warmth of the air prevents water from condensing to form clouds. As a result, high-pressure areas are often associated with clear weather.
