In the past, before technology was used to monitor the weather accurately, people looked at the skies, watched how animals and plants behaved, and relied on signs and superstitions to forecast the weather. Indeed, some people still believe that, when cows lie down or a cat sneezes, it is going to rain. Nowadays, scientists who study the weather, called meteorologists, use many different methods to make their forecasts. Satellites monitor our weather and send information to computers at special processing stations. On the ground, weather stations all over the world record wind speeds and directions, temperature, clouds and air pressure.
