Weather Instruments

A barometer is an instrument that measures air pressure. It helps predict weather changes, such as storms.

A thermometer measures the temperature of the air. It tells us how hot or cold it is.

A rain gauge measures the amount of precipitation (rainfall) that falls in a specific area.

An anemometer measures wind speed and helps determine how strong the wind is.

A barometer shows changes in air pressure. A drop in pressure often indicates that a storm is coming.

A wind vane shows the direction from which the wind is blowing.

Measuring wind speed helps predict the severity of the storm and potential damage.

You would use a barometer to check for low air pressure and a thermometer to see if temperatures are near freezing.

A rain gauge helps us understand how much rain has fallen, which is important for flood predictions.

Low air pressure often leads to stormy weather, while high air pressure usually brings clear skies.
