>>the consistent factor is the condition upwind. Bingo. I concur. I like slopes to have a clear area infront that it is at least 3 times the height of the slope. With MORE being substantially better.
Coastal slopes are so often good because the area in front of them is unobstructed and has a nearly constant surface temperature. We have to remember that there are many variables interacting in complicated ways. We're talking about the fluid dynamics of a compressible fluid (air). This is further complicated by the fact that we're standing on the surface of the flow's border. When I was in school the things that scared me the most were Antenna Theory and Fluids. I still consider them FM (******** magic). Luckily EE's didn't have to worry about fluids. The bottomline of slope evaluation is to fly it.
