NSSL studies weather radar, tornadoes, flash floods, lightning, damaging winds, hail, and winter weather out of Norman, Oklahoma, using various techniques and tools in their HWT, or Hazardous Weather Testbed. NSSL meteorologists developed the first doppler radar for the purpose of meteorological observation, and contributed to the development of the [[NEXRAD]] (WSR-88D). | NSSL studies weather radar, tornadoes, flash floods, lightning, damaging winds, hail, and winter weather out of Norman, Oklahoma, using various techniques and tools in their HWT, or Hazardous Weather Testbed.

In 1962 a research team from the United States Weather Bureau's National Severe Storms Project (NSSP) moved from Kansas City, Missouri to [[Norman, Oklahoma]], where, in 1956, the Cornell Aeronautical Laboratory had installed a 3 cm [[Continuous-wave radar|continuous-wave]] Doppler Weather Surveillance Radar-1957 ([[WSR-57]]). This radar was designed to detect very high wind speeds in tornadoes, but could not determine the distance to the tornadoes. In 1963, the Weather Radar Laboratory (WRL) was established in Norman and, in the following year, engineers modified the radar to transmit in pulses. The [[pulse-Doppler radar]] could receive data in between each transmit pulse, eliminating the need for two antennas and solving the distance problem.<ref name="NSSL-Hist">[https://www.nssl.noaa.gov/about/history/ "National Severe Storms Laboratory NSSL History"]</ref> | |||
In 1964, the remainder of the NSSP moved to Norman, where it merged with WRL and was renamed the National Severe Storms Laboratory (NSSL). Dr. [[Edwin Kessler]] became the first director.<ref name="NSSL-Hist" /> In 1969, NSSL obtained a surplus 10-cm pulse-Doppler radar from the United States Air Force. This radar was used to scan and film the complete life cycle of a tornado in 1973. By comparing the film with velocity images from the radar, the researchers found a pattern that showed the tornado beginning to form before it could be visually detected on the film. The researchers named this phenomenon the Tornado Vortex Signature (TVS).<ref name="NSSL-Hist" /> Research using this radar led to the concept that would later go on to become the NWS NEXRAD WSR-88D radar network. | In 1964, the remainder of the NSSP moved to Norman, where it merged with WRL and was renamed the National Severe Storms Laboratory (NSSL).
