Yeah...that is probably how I should have phrased that.  Does this issue with model  resolution occur over other mountain ranges, or is there something different about the Whites and Greens?

Because our mountains tend to be smaller and isolated the grid averaging can make MWN “look” like 5,000 ft.

More or less. To keep the same amount of air flowing over the mountain it has to accelerate when the depth of flow shrinks.

I get how it works in something with actual sides/top/bottom (like a nozzle or the aforementioned hose), but there is no compressing force above the mountain...wouldn’t the air just go up and over?

I'm trying to look through some soundings to illustrate this... you have anything good Chris that might be able to show this, like a BUFKIT snapshot or something?

It sounds very similar to like upslope precip and relationship to the inversion...inversion lowers and it starts squeezing out snow like toothpaste from a bottle.

You can see the inversion starts just above summit level, 750ish, and that’s what squeezes the flow.

I vaguely remember this from waaaaay back. I remember the professor said they will sometimes raise the ground below a bridge to increase flow and lower the water elevation. Seems counterintuitive, but it happens in certain flows.flow.jpg.f5f8e6465245732374d4c5dd5ff2b194.jpg

We do this with flow through a pipe to increase the pressure we reduce the space it is squeezed through

That’s actually pretty cool.   Were you in Civil E?

That's awesome.  Thanks dude.  

Perfect level to squeeze it out.  I think Mansfield's geography lends itself well to that.  The 4000ft ridgeline isn't like a classic pyramid peak/summit but it doesn't allow wind any options for going around.  I firmly believe the meso-scale topography of it plays into the upslope snow and winds.  It's not a Peak that wind can bend around, it has to go over it.

MWN is similar with the Presidentials all around.  Wind is locally forced to go up and over.  There is no easy escape around the terrain.
