Barometers are used to measure air pressure. As the air pressure increases the needle on the barometer moves higher. Increasing pressure typically means improving weather conditions. Decreasing pressure typically indicates the weather is changing and storms may be approaching. Learn more weather and air pressure in JetStream - An Online School for Weather.
