"Surface" temperature/wind doesnt show earth's surface values

@sPhoenix
At the "sounding" :
3200m ... -5°C
4800m ... -15°C
4800-3200=1600m ..... ΔT=10
10/1600 = 6,25/1000m = ISA (almost !) -
@sphoenix
Nice sounding! Is freely available ? -
Yes almost ISA in this case, but just an example. But in most cases the ISA temperature delta would be good enough problably.
This graph is from meteblue, it's only available for point+ subscriber i think.

Thank you -

Thank you. I took the example of Chamonix and Mont-Blanc temperatures just to underline the wrong temperature display by global models in mountain areas. You give the way to know the exact temperature, fine. But for me, just a quick look to the airgram, as you explained before, it’s enough precision.
What I have found through these questions, that’s the worse terrain resolution of the global models compared to there atmospheric resolution. And this is not obvious, as Windy show a very precise terrain resolution, we expect the same precision from global models, but that’s impossible ! -
