Analyzing wind drift with trigonometry explained.

[Fjold]

A very useful post for shooters to learn the basics of wind deflection.

Now you just have to explain how to dope the wind when you look down the 1,000 yard range and the range flags are pointing in four different directions.

Wait!! I thought SCIENCE is applied to things that can be quantified, calculated, or measured. ART is more nebulous. Things that cannot be quantified, calculated, or measured and is in the eye of the beholder (windreader). I disagree that wind can be broken down to the minutest increment and measured and factored into a firing solution. A number of people have shown up at matches over the years with their wizzbang wind reader thingys, charts, graphs, and .30+ caliber Superloudenboomeners and still get their @$$ whipped by those who can actually read the wind.

We shoot with quite a few of the top long range shooters in the nation and it is rarely made to look easy. It always comes back to: the only way to learn it is to do it. We have hosted two advanced long range shooting clinics in the last two years. I post invites on this and other forums to come out and shoot, but most would rather not leave the safety of the keyboard.

A couple of people posting in the long range forum have been out to shoot and I would like to hear their interpretation of wind reading.

Typo, sorry, corrected now

As for your pedigree I really don't care. I don't care who you are, what you say you can do, or who your friends are. it means nothing on a web board. if you want respect don't tell me what you can do SHOW ME.

I've shot with some very talented people and trust me standing in their shadow, yeah they make it look easy. I said look easy. not that it was easy just that at a certain level of skill your confidence grows to the point that you look at a problem unflustered. because you've already done it.

As per the scientific side of this if you had a gizmo that had an anemometer array that feed back info to a lap top and gave real time windage updates yeah it can be plotted, recorded, and the best solution applied to the dope.
and what I mean by array is a row of them laid out on the firing line every 25 meters sending data back for a constantly changing wind call.
then you just need to dial in your wind and try to pull the trigger when conditions match what you dialed in. then it's all about the timing of the shot. You wind call can be precise but if you do not match the conditions to the moment you pull the trigger it's all for not.

the thing is I'm a 42 year old Toolmaker that hit trade school right out of High school and you should see the look on people face when you tell them that a 10 mph wind @ 45˚ is not half value it's .7 or .707% if you want to be that precise

if you want to see a grown man cock his head and wrinkle his lip tell him that.

just take that wind angle and look up the Sin x your wind speed and done.

MMMmmmmm - Huuuuhhhhh. Yep

[diver160651]

Maybe a separate thread on mirage angles, boils, dialing back, vegetation, dust, terrain features, wind shadows, low position mirage VRS elevated, gravity distance.... The stuff really doesn't end. But at the end of the day, wasn't the op trying to give a mathematical formula for one only one read angle?

I don't think it was meant (I could be wrong) on how to read the wind.

Maybe we can get a thread about the art of piss drift during pissing competitions?
OP never spoke of how to read the wind. He posted on its effects.

I have a little bit of experience in shooting in the wind and would be glad to help anyone who REALLY wants to learn how. What do you have in mind?

[kcstott]

pretty much.... right??

Yeah...?Ahhnother8 always has a chance,but was beat by a woman yesterday.

We were up at Ojai, playing with a little "mini clinic" where we all sat around calling wind and a hard holder put on the dope and took the shot. It was interesting to see how different people read wind and it was telling to notice how much the geography of a range effects the wind.

Ultimately fluid dynamics is a thing we can only sort of model, and as an anemometer array along the flighpath would be a nearly perfect macro example of heisenberg's uncertainty principle I doubt we could ever really measure the wind. Doesn't mean we can't get close though.

That closeness is the art. It's the soccer player's bicycle kick at half field into the top corner of the goal. Yes there is science behind it, or at least science can explain it, but the skill has transcended conscious thought and become a gut feeling. The internalizing of a practice, to the end that it becomes just another thing you do is absolutely ART. But I, like others don't get on the range nearly enough to do this, so while I'm at work and wish I could be shooting I'll read whatever I can in hopes that I can maximize my actual trigger time. And then I will go to Coalinga for regionals, and I too will get beaten by a woman.

If this is a real offer then where do I show up? Every time I'm at Coalinga I estimate too much wind at 300 and too little at 600, and then mirage shifts and I have no idea how to recalculate. I do a lot of hope, walk it in and surf it as long as I can. NOT a good way to shoot at Coalinga.

Johnny called me after shooting with highpower790 up there, and he was in an excited panic. Total paraphrasing "I was scoring for him, and he just wasn't shooting. Everyone else was shooting 8s and wide 9s and he was just sitting there. Then he looked behind us then he started shooting and he nailed an x! I waited for him to be on the gun before I looked behind me and all that was back there was the smoke stack and the trees. And then I realized it was the ****ing smokestack and the trees!!! Sneaky sneaky!"

I have so much to learn.

No, that isn't how Heisenberg works. It would, however, be a real life example of chaotic systems.

[milotrain]

I know that's not how Heisenberg's uncertainty principle works fundamentally. The macroscopic case of that principle is that you cannot measure something without influencing it (or at least that's what I was taught, ). This is a perfect example of that even if it's not correct

Of course the offer is real, but in order not to derail a thread on theoretical wind drift, I will PM you information on when/where to get help with real world wind drift, when shooting long-range. Shooting in Coalinga is a challenge and a hoot!! If you can be successful there and/or Sac Valley, you can be successful at most any range in the world.
