When I was a student pilot and reading the wind section of the manual I remember the illistrations showing high and low pressures on the front and back sides of the ridges etc. I have a book that also targets back country flying and it addresses much of this. However, in a plane you are generally flying within areas the air is a bit more stable vs being relatively close to the ground. Not that any of this has made me a better wind reader but I have been thinking about it ever since I shot that mountain lion a month ago and how it all applies to the bullet path.
I noticed a transition from updraft, hide area, to down draft, within a relatively short distance down the slope of the finger I was on that day. I also noticed a pressure shift in kestrel
. The pressure shift was not great enough at 1000 to make any difference but at 1500-2500 I do believe it needed to be accounted for. I have not shot beyond 1500 so I have no clue. ??
Back to the point, on the backside of mountain the wind tumbles in a clockwise rotation, creating up and down drafts. Have you guys noticed this and thought about how to account for bullet path relative the invisible air stream at say 100 feet off the deck?
