DopplerOHYEA!

OH YA! The Doppler effect is the bomb diggidy. Bats use the Doppler effect to live. They need it for everything in their life. Without it, they could not function and would have been long extinct. The bats use Doppler effect for moving. In some way, they send out sound waves that bounce and reflect off of most things in the world. The vibrations reflected tell the bat where they are in relation to different objects, including their prey.

Another common use of the Doppler effect is in weather prediction. They use a Doppler Radar system that sends pulses of radiation. This not only tells the "linear speed" of weather systems, but "radial speed". These two combined help determine exact movement of the systems. The radiation sent out is reflected by the weather and return to a computer that measures the varying frequencies. The computer creates the visuals for the weather systems, and that is what we see when we watch our news during the day.
