Was mountain wave activity observed near the accident?

Figure 6. Lidar observations of a localized flow reversal within a 60 m/s upper-level jet at 11.5 km MSL. This is a unique instantaneous (1-min) measurement of the breaking of a mountain wave. Negative radial velocities represent flow toward the lidar.
