April 15-June 16: Storm penetrations by high-performance jet aircraft enabled ground-based scientists to check radar returns against airborne measurements of in-cloud turbulence for the first time. A two-month experiment by the Air Force Systems Command's Cambridge Research Laboratories and the National Severe Storm Laboratories of the National Oceanic and Atmospheric Administration at Norman, Okla., fingerprinted the wind to gather faster, more accurate information to identify tornadoes and devastating windstorms. Hazardous air currents swirling inside storms registered a distinct impression on doppler radar. Radar signals were processed through an electronics package to permit observers to pinpoint and measure gusts or turbulence. With severe storm patterns identifiable, observers could forecast their threat to aircraft in flight and people and installations on the ground. (AFSC Release OIP 101. 73; AFSC P10)
