1.1 AIRCRAFT MEASUREMENTS OF TURBULENCE: LENGTH SCALES, SPECTRA, BUDGETS, AND THE PREDICTION PROBLEM

The authors gratefully acknowledge the enabling contributions Dr. Timothy Crawford made to these aircraft turbulence measurements and analyses. This work could not have been done without his scientific vision, unique engineering skills, and remarkable management ability. 2. Introduction. The goal of our direct airborne measurements of turbulence is to investigate the structure and dynamics of strong clear air and refractiv
