Stratospheric Turbulence Analysis.

Abstract

A model was developed to combine radiosonde observations with ultrasensitive well-calibrated radar measurements of clear air turbulence to provide estimates of two eddy parameters, the eddy dissipation rate and the eddy heat diffusion coefficient. The eddy parameters were obtained as volume averages over 1 km thick layers and time averages over several hours. The model was tested using simultaneously obtained radar measurements and pilot reports of turbulence intensity from a U-2 aircraft. The model was also shown to be consistant with other reported radar and aircraft measurements. (Author)
