To determine the probability of turbulence occurring in the waves seen in the imagery, pilot reports were examined for correlation. Approximately 90% of the severely turbulent days had wave signatures in the water vapor imagery during the time period of the reports. The wave signatures on these turbulent days appear different in the imagery from the signatures on the days that were less turbulent. The turbulent days had complex wave patterns with apparent interference and crossing wave fronts that extended downwind for a significant distance. The days that were less turbulent had wave signatures that were much simpler with wave patterns that could be characterized as linear.
