Doppler Radar




The satillite image a above is an example of a doppler radar, which gets its name from the "Doppler Effect". The Doppler Effect works in a fairly simple way. Satillites are postioned in specific places and send out waves which retrieve the sound of hail, precipitaion, or even dust. The time it takes for the signals that were sent by the satillite to return determain if the weather is moving toward that region or away from it. This is the most reliable tool when it comes to planning for weather.
