The only thing more dangerous than a tornado is a tornado that occurs at night. People have some weird need to want to see the tornado before they seek shelter or take any other action. Seeing a tornado at night is usually almost impossible, but last night it wasn't. Meteorologists at the National Weather Service in Jackson, Mississippi were able to confirm the presence of a damaging tornado last night based completely on radar data, proving the effectiveness of its new dual-polarization technology.
Doppler weather radar is one of the most useful tools available to track the weather in almost real time. Since the technology came into regular use in the 1950s, researchers have made incredible advances in the abilities of basic weather radar. Not only does weather radar track precipitation, but it can also detect bugs, bats, dust, road traffic, tornado debris, and even the setting sun.
