Today’s Tip: Predicting Weather
Changing weather means changing air pressure. Decreasing air pressure indicates the approach of a low pressure area, which often brings clouds and precipitation. Increasing air pressure often means that a high pressure area is approaching, bringing a fine and clear day. A barometer measures air pressure and is a well-known instrument to predict weather.
Animals sense the movements in air pressure that precede all weather changes. Watch the animals around you and see if you notice changes in their behavior with various types of weather. Right before a rain, insect-eating birds, such as swallows, have a tendency to fly much lower to the ground, and bees and butterflies seem to disappear from the flower beds they usually visit.
