This report summarizes the Integrated Turbulence Forecasting Algorithm ITFA Meteorological Evaluation conducted by ACT-32O from January to August 2000. The ITFA, developed at the National Center for Atmospheric Research NCAR, combines several turbulence forecasting techniques into a single algorithm that produces a forecast of the potential for high-level, clear-air turbulence. The purpose of the evaluation was to provide a subjective assessment of the performance, characteristics, and trends of the ITFA before and during periods of widespread, significant turbulence. Evaluation results indicate that ITFA has the potential to be a useful tool for the detection and prediction of jet-streamwind shear induced upper-level turbulence. In addition, several recommendations were made for further development.
