Weather Tools What 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.
