Weather Instruments by Brian Fontaine

Meteorologists use many different types of instruments to collect data about the weather conditions.

Thermometers measure temperature

Rain gauges measure the amount of precipitation that has fallen.

Barometers show where areas of high and low pressure are. High pressure signals what kind of weather? What temperature air?

The mercury barometer was invented in 1643 by Evangelista Torricelli. content/uploads/2009/09/merc_barometer.jpg

Aneroid barometers are more commonly used today.

With the Data from Hundreds of Places, Weather Maps Show Lines of Barometric Pressure

Wind Speed is Measured by a Anemometer An Aerovane

Wind Direction is Measured with a Wind Vane

Hygrometers Measure Humidity

Psychrometers also measure humidity

Weather Satellites Collect Data from Space

And take pp-to-the-minute ictures of weather patterns

Doppler RADAR detects cloud cover and precipitation by using radio waves.
