Weather ToolsWhat are they? What do

they do?

The Most Common Weather Tools Are:

• Thermometer• Wind Vane• Anemometer• Barometer• Rain Gauge

• Sling Psychrometer

Thermometer• A thermometer is

a weather tool used to measure

the temperature.

Thermometer• A thermometer

measures temperature in

degrees Fahrenheit or

degrees Celsius

Wind Vane• By observing wind

vanes, we can know the direction of the wind. Knowing the

direction of the wind is an important part

in predicting the weather.

Wind Vane• Wind vanes indicate the

direction of the wind using

cardinal and intermediate

directions.

Anemometer• Wind speed is an

important part of weather.

• An anemometer is a weather tool that measures how fast the wind is blowing.

Anemometer

• An anemometer is a weather tool that measures wind speed in Miles Per Hour (MPH).

Barometer

• Barometers can help you predict

good or bad weather.

Barometer

• Barometers measure air pressure in

pounds per square inch (PSI)

Rain Gauge• A rain gauge is a

weather tool used to collect rain and determine how much rain has fallen.

Rain Gauge

• The rain gauge is really just a jar with a ruler on it.

Rain Gauge

• A rain gauge is used to measure the amount of rain in inches.

Sling Psychrometer

• A sling psychrometer measures relative humidity.

Relative Humidity

• The relative humidity tells us how “full” the air is at the time of measurement.

• For example, 90% relative humidity means that at that moment the air is holding 90% of the maximum amount of water it could.

Sling Psychrometer

• A sling psychrometer measures percent of relative humidity.
