And finally, our meteorologists can't control the radar. Yes, if you see the sweep going around, its live. Most importantly, ours is operated from a control panel in our First Warning Weather Center . And we have recently added Storm Track software which allows us to draw a map projecting where a storm will go and when it will arrive. No, not all radar is doppler radar.
Regular radar detects rainfall and can tell how much rain is falling at any given location.
Doppler radar does that AND can detect how much the rain is being blown around by the wind. This makes doppler radar especially helpful in spotting severe thunderstorms and other damaging weather. On our radar display, this turbulance is shown as purple. Radar works by bouncing a radio signal off the drops of rain and timing how long it takes for the reflected signal to return. This turbulence generally occurs in strong thunderstorms.
