Work setting "Weather File" FSX:SE

In FSX: SE, using the "Weather File" mode causes the wind speed, direction, and OAT to not change with altitude. All parameters remain the same as they were on earth. Screenshots for explanation c height 10000ft (AOT=16)
and 15000ft. (AOT=16)

Just like it was on earth.

With update weather data have changed, but what they correspond I do not know.

and, I know, again the ground weather was loaded at an altitude of 15,000 ft
