Abstract

The Air Force Research Laboratory began a recent investigation into High Altitude Turbulence after a request from the Air Force for more basic research leading to improved forecast of this phenomenon. The laboratory sought out recent flight data to assist in the understanding of high altitude turbulence and to use as verification for forecast models. With the assistance of the NASA Dryden Flight Research Center, data from an ER-2 flight was found that included persistent moderate to high intensity turbulence over a long distance for a range of altitudes. The data has been analyzed and compared to some turbulence forecasts and other analyses techniques. The in-flight turbulence was not strictly a traditional "mountain wave" encounter, and has proven to be a challenge to understand and to model.
