Doppler spectra of Tornadoes
- 1958: 1st measurement of tornadic winds
- 1973: 1st measurement of tornadic winds with pulsed Doppler radar (NSSL)
- 1977: 1st direct measurement of tornadic winds with NSSL’s high
- OU/NSSL cooperative effort
1955: James Q. Brantley of the Cornell Aeronautical Laboratory (CAL)
built a CW radar for the detection of weather motions (Brantley and Barczys,
6th Weather Radar Conference, 1957). This CW Doppler radar (or one like
it) was a Navy radar modified by Brantley for use by the United States
Weather Bureau (USWB) in 1957, 58, and 59 in attempts to detect tornados
on the Great Plains. On June 10th, 1958, a major tornado entered the city
of El Dorado, Kansas and was observed with the USWB’s CW Doppler radar.
- 1973, Dusan analyzed time series data obtained from the Stillwater Tornado.
- 1977, The high PRF capability that was added to the Norman Doppler radar
was a cooperative effort between OU (Dr. Tuma) and NSSL.
