According to the National Weather Service, the first upgraded “dual-pol” system (NWS WSR-88DP) at Vance Air Force Base near Enid, Oklahoma. The National Weather Service began the transition to dual-polarization radar in the early 2010s. Better information about shape, size, and composition of the targets allows for improved discrimination of precipitation type (for example, Is it heavy rain or hail? or Is it snow or freezing rain?) There are even products that can be derived from dual-polarization radar that can help identify debris associated with a tornado in real-time and improve rainfall estimation. According to NOAA website, “Dual-polarimetric radar transmits and receives pulses in both a horizontal and vertical orientation.” This means the returned echoes contain information in both orientations about the raindrops, snowflakes, sleet, and hailstones.

Southeast United States Weather Doppler radar and satellite will display rain, snow, ice, warnings, statements and advisories on the map. Ok, we finally made it to dual-polarization. Southeast Weather Doppler Radar and Satellite Map. My master’s degree work involved the use of early WSR-88D radar data to track and locate landfalling hurricanes.

In fact, most tornado warnings today are based on Doppler radar identification.

With such information, meteorologists are now able to detect rotation in storms that could be indicative of a tornado. This Doppler effect also explains why the pitch of the horn of train sounds different as it approaches and moves away from you. We gather airborne Doppler-radar wind and precipitation measurements from the P-3 and G-IV aircraft, quality control the data on the aircraft, and then deliver it to our National Weather Service partners in real-time. From that information, we can determine velocity towards or away from the radar (radial velocity not true wind velocity by the way). Since we know the phase (shape, position, form, frequency) that the radar beam was transmitted, if scatterers (raindrops, etc.) are moving they will shift the phase of the returning radar echo. These radars introduced the vital life-saving capability of Doppler shifted phases. This was a part of the National Weather Service modernization effort in the early 1990s. weather radar network to the WSR-88D “S” band system. Around the time I was heading off to college in the late 1980s, the National Weather Service, Department of Defense, and other partners upgraded the U.S.
