Weather Data Tools
2
Thermometer

• Measures air temperature

3
Barometer

• Measures air pressure
• High Pressurefair weather
• Low Pressurewet, stormy weather

4
Psychrometer

• Measures the amount of water vapor in the air,
  which is called relative humidity.

5
Anemometer

• Measures wind speed

6
Wind Sock/Wind Vane

• Both devices are used to determine wind direction.

7
Weather Balloon

• Weather balloons carry electronic equipment that
  can measure weather conditions high in the
  Earths atmosphere.
• They can measure temperature, air pressure,
  relative humidity, wind speed and wind direction.
  

8
Radar

• Radar is used to find the location, movement,
  type and amount of precipitation.

9
Satellite

• Weather satellites provide images of weather
  systems.
• This is the weather tool that shows cloud cover.
  
• Satellites can track storms and measure wind
  speed, humidity and temperatures at different
  altitudes.
