[QUOTE="Mike Belt, post: 4537742, member: 69"] Think of wind as water like when a damn breaks. The rush of water will take the least resistance. When it does hit resistance it will alter the direction of flow. Over simplified but basically the same outcome. An east wind blowing perpendicular to a north/south ridge may deflect off that north side and change the direction of air flow FOR THAT PARTICULAR location to a more northerly direction. Get up on top of that ridge and the flow may very well be easterly again. Much of this depends on wind speed though. With higher, more consistent wind speed as those ridges deflect direction they suck the air from the hollow creating a vacuum. Something has to fill that void and that is air being drawn back into that void and in all likelihood, from another direction opposite that of the actual wind direction. Again with those higher wind speeds this often creates a backflow of air. When this happens you could be sitting on the side of a ridge, let's say the north side as in the above example with an east wind blowing in your face. You think you're hunting the right wind for seeing deer towards the ridge south of you. What could be happening is that the wind is bouncing off that north ridge above and behind you and towards the top it's curling up and back over sending it a completely different direction headed back and over that south ridge and dropping your scent exactly where you don't want or expect it to be. When hunting ridges and hollows it happens all the time that you may have a "ground" direction and a completely different upper wind direction. Ever wonder why deer are blowing from upwind of your location? It's actually easier to make a hunt plan with consistent higher winds than light winds. They are more predictable.
