Vertical component of the wind

After SU6 in MSFS2020, I noticed that the descending winds of the wind on the leeward slopes became significantly aggressive. Fake in them, the glider sharply falls into the air hole, while losing a lot of height. I suffered for a long time and lost in guesses. Yesterday I decided to check and understand what is happening with the wind and its vertical components on the leeward slopes. I posted a glider over the western slope and turned on the active pause. Weather preset: No clouds, wind speed at all heights are 10 knots. 1 Stage: Wind direction 273 ° M. On the video, we observe a fairly stable direction of wind 272-275 ° M and its speed of 13-14 knots. Accordingly, we observe the stable speed of the vertical component of the wind in 3.5 units. Stage 2: I changed the wind ruling at 93 ° M. In the second half of the video, we observe a very unstable direction of the wind 65-125 ° M and its speed of 11-18 nodes. At the same time, the speed of the vertical component of the wind varies from 3.5 to - 8.5 units! It’s terribly and very wrong!
