Weather Tools

Meteorologists use weather tools to predict the weather


A thermometer helps measure the temperature of the air. A thermometer is a glass tube containing alcohol or mercury, so when the air around the thermometer heats up it expands and moves up the tube. Then it shows the temperature.

Rain Gauge

A rain gauge, as implied by its name, is used to measure the amount of rainfall over an area over time.


A barometer measures air pressure. A higher air pressure means it will be clear and good weather. A low air pressure means there may be storms or rain. The air pressure helps meteorologist tell if there could be storms in the days to come.

Weather Satellite

Weather Satellites can be used to take picture of large-scale air movement and keep track of them. The meteorologist then goes on to compile and analyze the data with computers to predict the weather.

Sling Psychrometer

A sling psychrometer is used to measure relative humidity. To do this meteorologists use two thermometers, one of them has a wet cloth around it. You the swing the psychrometer around and the water on the one thermometer evaporates making the temperature on that thermometer lower.


Meteorologist use an anemometer to measure wind speed. It is basically three cups that capture the wind making the anemometer to move. The cups are attached to a dial that shows the wind speed. This can help meteorologist see if there might be a storm coming.

Why weather predicting is important to me?

Weather predicting is important to me because it keeps me save. If there was ever a tornado or hurricane, meteorologist are able to predict it way in advance giving us time to prepare and stay safe. It also is important because it helps you out with planning. For example if it's going to pour later on and you don't know, you may not have packed an umbrella. Or if you wanted to go to the beach this week, but have no idea when it is going to be warm and sunny, meteorologist can help predict that.
