Doppler Radar

http://www.weatherusa.net/blog/images/doppler-orlando-1943.gif

Doppler Radar is used to view weather that is near by. The original doppler radar is a system that returned echoes from an object to determine radial velocity. Weather stations have used the system so much that doppler radar today is known as weather radar instead of it's orignal use. This doppler picture is one of hurricane Charlie that hit Florida in 2004.
