"Kyle Boatright" wrote Taking Kennesaw "Mountain" and Stone "Mountain" out of the equation, you need to get pretty far North in Georgia (75 miles from Atlanta, at least) to find anything more than 500' hills... I'd guess wind shear was the source of any turbulence. KB It was my understanding that you could get standing waves that could go for 100 miles, or more. Wrong? -- Jim in NC

Wrong? -- Jim in NC True (even farther, but the amplitude decreases as you go farther downwind. The rotor is at ridge level. There can also be a lot of wave turbulence at the tropopause but that would be above 310. Turbulence in the middle flight levels is usually shear unrelated to mountain waves. The mid flight levels are in the laminar portion of mountain waves and it is amazingly smooth there. Mike MU-2

Wrong? -- Jim in NC No doubt about that, but the real mountains in Georgia are pretty far North and/or Northeast. Since wind from 285 close to due West, I woudn't think anything more or less West of Atlanta would cause standing waves anywhere near the city.. Of course, all of this goes back to what the original poster considered to be "Near Atlanta".. KB
