What you see is the radar beam hitting different an inversion in the air - or air masses with different densities (IE cooler air below warmer air). Normally the lowest tilt from the radar is at 0.5° from the base and shoots out - effectively getting higher and higher above the ground the further the beam goes. The differential densities in the air forces the beam to bounce down and hit the ground (in the field we call this superrefraction. Wiki it if you are bored). The energy reflected back to the radar is then seen and interpreted as just that...energy and hence colorized by the amount reflected back. Upcoming changes to all National Weather Service radars will be able to differentiate different phases and thus...seeing ground like that...will hopefully be a thing of the past.
Sorry bills... was trolling and had to jump the gun. |

| I held down the F11 key on my mac, it lowered the volume, and I did not laugh, so I am a good person? |
