“Called dual polarization, the upgrade will play a big role in spotting tornadoes, meteorologists said, because the new technology can see the unseen.
Dual-pol radars are so precise that they can see individual types of precipitation, such as hail and rain — a level of detail that will come in handy during severe weather.”
"As long as it gets lofted high enough for the radar to see it and sample it, it has a really distinct signal in dual-pol," said Paul Schlatter, the NWS meteorologist in Norman that is training forecasters on the new radars.
This will come in handy if, say, a tornado is cloaked in a rain cloud, making it invisible to the naked eye — and current Doppler radar.”
