Doppler Radar- Based on the Doppler effect, this radar system uses a transmitter to emit microwave radiation and a directional antennae to receive and measure the time of arrival of reflected pulses from distant objects. An important component of meteorological forecasting, Doppler radar creates an atmospheric profile of clouds, including their reflectivity (size and type of particles in the air, indicate precipitation type), velocity (speed and direction of the air relative to the radar station), and intensity of precipitation. Here, Doppler radar creates an image of Hurricane Charley over central Florida, showing its location, wind and associated cloud and precipitation movement, precipitation intensity, and DBZ values (equate to approximate rainfall rates) (http://kwilklab.wordpress.com/author/kwilk1984/).
