Good stuff, A0.
A trick that helps me visualize what's happening is to think of the air as water, but taking into consideration the effects of temp and baro press that A0cake illustrated above.
The first thing is to get good at estimating the wind speed based on its effects on the vegetation and objects. Then, learn the difference between near wind and far wind, and sometimes even near and far winds in different directions. Once you get reasonably proficient at that, then you start adding in things like accounting for pressure gradients, temperature anomalies, and so on. As A0 pointed out, some of this is very AO-specific (no pun intended).
Tall buildings introduce some weird air flows that can be a real bitch to shoot around. I once got invited to help with a nuisance bird control shoot in the downtown area of a big city using suppressed .22 rifles with subsonic ammo, and I got more education about wind around tall buildings those two days than I could have PAID for anywhere. BTW - BulletFlight works just fine for doping .22s :D
Great info, great thread. Wind just plain kicks your ass. It is wind that makes a spotter an absolute necessity. Its a cool study and I am learning more on every shoot. Our location has variable wind with consistent changing direction. Its very interesting.
