APPLICATION OF DOPPLER WEATHER RADAR TO TURBULENCE MEASUREMENTS WHICH AFFECT AIRCRAFT
Analysis of thunderstorm turbulence hazardous to aircraft operation and coordinated Doppler radar observations indicate a high potential for Doppler radar utilization particularly the mean velocity spectrum breadth observations in defining severe turbulence areas. The mean Velocity Processor (MVP, the first real-time display of Doppler radar data) and the Multi-moment Ling Display (MMD), both developed at NSSL, are utilized with the radars to study vortex motion, turbulence, and wind shear areas. In addition, the Plan Shear Indicator (PSI) developed by the Air Force Cambridge Research Laboratory (AFCRL) was also employed. A number of severe convective storms were penetrated by an instrumented aircraft directed into areas which analysis inferred to be turbulent. Aircraft recorded turbulence and concurrent Doppler data are compared. Utilization of the spectrum breadth calculated from the mean velocity data as a turbulence signature is discussed. Vortex motion signature is also defined. (Author)
