Ocean Buoys
Abuoy is an object that floats on water, and is often used to warn boats away Prom dangerous places in the ocean or on a river. But some buoys have special instruments on them. These buoys can tell us the temperaturę and other things about the conditions of the atmosphcre.
Weather Satellites
Humans send satellites into space to travel around the Earlh. The satellites send back information to SCWUtists on the ground. Some of the information fbsy ęive us is about the weather and the Earth's tempera
