The up and down sides of rotors relative to ridges
The downwind ridge can generate a wave of its own. What I tried to say
earlier is that this second wave (not to be confused with a secondary peak off of the first wave) can either reinforce or cancel the upwind wave with the result being either much stronger downwind of the second ridge or little to nothing at all. There have been books written on this. A good example is Mark Palmer's "Practical Wave Flying". On 4/7/2016 7:39 PM, son_of_flubber wrote: Hoping to clarify, my upwind Ridge A generates the primary. My downwind ridge Ridge B is downwind of Ridge A (and lower in altitude). Secondary wave lift and rotor forms upwind of Ridge B. Oftentimes, ridge lift between the rotor and the ridge. -- Dan, 5J
