New Weather Technology
Updated: Monday, November 12 2012, 03:19 PM EST
After nearly a quarter of a century, the National Weather Service is upgrading doppler radar. The new technology is called Dual Polarization. The conventional doppler radar signal vibrates horizontally through the atmosphere. The new dual polarization or 'dual-pol' signal vibrates both horizontally and vertically.
Meteorologists say this new technology will do a better job of detecting snow, heavy rain and hail. They say that will lead to more accurate watches and warnings and could help you be better prepared for the storm.
The upgrade comes at a high cost, $225,000 for each of the 160 sites in the country. Meteorologists say it could take years before all the dual polarization benefits are known. Some researchers say the upgrade could save the U.S. $700 million a year in weather related damages.
