Explain how a barometer can be used to predict future weather conditions in a location.

A barometer is a popular instrument used in determining present and future weather conditions. An increase in pressure will typically indicate pleasant weather conditions. When the pressure decreases, unstable weather conditions will prevail. These conditions can develop into stormy weather patterns.

Barometer is an instrument used to measure the atmosphere's pressure. The high air pressure relative to average levels is associated with calm and sunny weather. On the other hand, low pressure is associated with bad weather, high winds, and rain.
