Weather Instruments

By: Zachary Ladowski


A thermometer is a instrument that measures the energy of the air molecules. When the air around the thermometer heats up, the liquid inside goes up as well.


A barometer is a instrument that is used to measure the air pressure. It shows this by having air push down on the meter. This allows us to tell whether the weather will be either sunny, cloudy, or even stormy.

Sling Phychrometer

This instrument is used to measure the relative humidity of the air, the is done by have two different thermometers(different types) that are wet, then you spin both around, then the water will evaporate showing you the relative humidity.

Rain Gauge

This instrument instrument measures the rain fall, this shows data only when there in precipitation. You see the measure when it is collected in the gauge.

Wind Vane

This instrument is used to measure the direction of the wind is blowing. We see this when the wind is blowing.

This instrument helps us find out the speed of wind is blowing. We see this measure when the wind is blowing.

Weather Maps

All weather maps indicate atmospheric conditions above a large portion of the Earth's surface. Meteorologist use weather maps to predict and forecast weather. We get information from other data such as satellites.

The hydrometer measures the water vapor content of air or the humidity. It is measured by modern used electronic devices use temperature of condensation. We find this by using the relative humidity.

Weather Balloons

The weather balloon measures weather conditions higher up in the atmosphere. The weather balloon sends back information atmospheric pressure, temperature, humidity, and wind speed with a device called radiosonde. We find information from the balloon as the balloon goes up by the radiosonde.

The compass is a navigational instrument for finding directions. We find this from the magnetic fields of the world.

Weather Satellites

Weather satellites are often used to photograph and track large-scale wind and air movements. Meteorologist analyze and compile the data to find on their computers. We find this information from multiple pictures taken of Earth's weather as it is moving, like a hurricane.
