I have seen it at Thunder Ranch at the end of the bullet's flight, especially with things like a 308 or 223 which are not moving very fast, winds bouncing off terrain features carry the bullet up. But this is not to be confused with a straight horizontal wind driving the strike up due to the bullet rotation on the air. At Thunder Ranch, Clint, Jacob and I were shooting his rifle the "Hammer" to about 1200+ Plus yards across the valley to an opposite hill. The bullet was randomly impacting 10ft over the target at times. Well a light snow started and the winds where blowing up the side of the hills carrying the bullet, this can be seen in the snow. We were shooting 168gr bullets out of a 20" rifle over 1200 yards away.
Sacramento Valley Range has a Terrain feature around 500 yards give or take, that is in the line of the wind which has a slope on the up wind side which, Jumps the wind across the range giving you a vertical component at the right movement. It's not rocket science, it wind hitting something and bouncing off.
Cause and effect, Terrain features diverting the wind giving it a vertical element.
Same with the wash at RO, it is in the path of the prevailing wind, which lifts the wind up in a ramping fashion around the 900 yard line. Which at sea level, if you are shooting a 168gr bullet will cause a vertical because the bullet is going Transonic a lot of the time.
Straight winds unaffected by Terrain are not causing it, terrain, absolutely can cause it, and during our class at Sac Valley I demonstrated this in detail.
It's not Voodoo, wind is water, when moved, and funneled and squeezed between berms and other terrain feature, even small ones, it increases the velocity, like rapids on a river. Wind is water...
When a person is at the range and flags are present from 200 to 1000 yards and one flag is going the wrong way, the Prevailing winds are not clashing, the wind is bouncing off something like a berm and moving locally, you don't have a prevailing wind out of the East with a narrow spike coming from the West, the air doesn't flow that way. You have a local disturbance caused by something like berm, hill, sand dune, wash, etc...
And I hate to say, I think the point was missed earlier, when I say we saw 40" in vertical at 700 yards, that was not due to MV variations, but shooter variations. Not Breaking the Shot at the bottom of the breathing cycle, but at different points, caused this vertical -- the SHOOTER, not the MV, the Shooter. Breaking the shot incorrectly can cause a person to hit above an E Type one shot and below the target on another without changing a thing but where and how they executed the shot.
Science for sure, but not the science of the bullet climbing the wall of air it is falling through.

This is worth copying and putting in your data book. Read this again in your spare time. Pay attention to it. This is worth way more than you know. Frank mentions snow and the SEE, and we have seen the same thing in mountains with low cloud cover, and in other places when there is a lot of smoke out there.
This may not be about verbiage on wind calls, but this post by Frank is very important to those who may not understand what they have been seeing. To me, this from Frank is worth the whole 3 pages of post here. Just from this dumbass country boy opinion.
And not to pick the scab on the sore, I'll take all the factory match 308 ammo I can get, leave the brass in the grass, and fuck reloading, its the shooting time that matters most. (308 here guys, not so on the 375 Cheytac, I will hunt them lost brass hard.)
Wind call for me? (working off a known scope setting.)
Spotter up? Spotter up.
Shooter up? Shooter up.
Hold.
Hold.
Hold 3 mils left.
Shooter up, 3 mils left.
Send it.
Hit.
Or:
Miss, hold 1.5 mils left and .5 low, send it.
Shit, Bang...
Miss. WTF did you do?
DamnifIknow.
Well, the target is GONE dumbass.
Screw you too...
And so it goes around here.
It's your playground but I think it for the good of the whole group if you or a mod delete all here that's not directly associated with wind call verbage.
