  1. Research on the impact of mountain waves on general aviation Deon van der Mescht Templ ref: CRS–CC-PRES-TEMP-003.2 Doc Ref no:

  2. Mountain wave definition The American Meteorological Society (AMS) defines a mountain wave as an atmospheric gravity wave which forms in the lee of a mountain barrier as statically stable air passes over the barrier (AMS 2010). Templ ref: PPT-ISO-colour.001 Doc Ref no:
