...Still don’t understand why there is wind info given for the surface and then 2000/3000 ft MSL etc in areas where the elevation of the ground is like 5000 or 10000MSL etc in like Colorado or mountainous areas.
I would love to hear a good explanation for this question. I live in Colorado, and there are wind barbs on the airgram at hPa corresponding to an approximate elevation of several hundred feet beneath the dirt I'm standing on. Also, I wonder about that sam issue as related to the map display, when you can set altitude based on pressure. Just skip the 850-1000 hPa range?
P.S. I think when I finally have all this sorted out well enough, I'm going to post a very thorough "explainer" with a bunch of screenshots so nobody gets as confused as me again (⊙.☉)7
