Types
-
Thermometers measure air temperature; barometers measure air pressure; psychrometers measure humidity; anemometers measure wind speed; and weather balloons and satellites measure all of those conditions.
Use
-
These instruments can help predict the weather: air temperature dictates precipitation types from rain to snow; air pressure indicates whether it will precipitate or not; humidity affects comfort level as high humidity can create uncomfortable conditions; and wind direction moves weather systems.
Location
-
Weather instruments are used in many different locations. Advanced instruments like weather balloons or psychrometers are generally used by weather stations, airports and military bases. Thermometers and barometers are available in models that anyone can use.
