"High to low down you go"
Works in three ways
-Altimeter error - if pressure or temperature decreasing altimeter will overread
-Jetstreams when southbound, decreasing temp=you'll go under it
So do you mean "you'll be OK at that level as you'll go under it" or "you need to descend and go under it"? How does that translate to my increasing temp? (I may sound cynical but that's not my intent.)

Also, I suspect that the third thing on the 'High to Low' list is about being lower than expected should you fail to change QNH, is that what you meant?

Last;
Remember this - Lenticular cloud = Mountain wave turbulence. Sounds obvious but when I did it there was more then one correct answer to their question.
I had this topic, the question asked where the rotor turbulence would be found and there were two very tempting choices:
  • in the trough between the lenticular clouds
  • under the lenticular clouds
I drew a diagram and went with 'under the clouds' and must have gotten it right.

PS is anybody else sitting this in the near future?
