Barometer, Thermometers


Your barometer is just as accurate a weather forecaster as the TV meteorologist you watch with the news. Under most conditions it forecasts weather for the 12 to 24 hours ahead. Its mission is to measure air or atmospheric pressure and indicate its rising or falling.


A THERMOMETER measures the air temperature. Most thermometers are closed glass tubes containing liquids such as alcohol or mercury. When air around the tube heats the liquid, the liquid expands and moves up the tube. A scale then shows what the actual temperature is.

WEATHER SATELLITES are used to photograph and track large-scale air movements. Then meteorologists compile and analyze the data with the help of computers.
