1. Weather Data Tools

2. Thermometer ► Measures air temperature

3. Barometer ► Measures air pressure ► High Pressure=fair weather ► Low Pressure=wet, 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 Earth’s 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.
