How to consider wind resistance for open shelters.

[JuliaKH]

Hello,
We have an open stable for horses with just one opening. I would like to make another opening. Then there will be two openings on the same wall, with part of the wall left between the openings.
What I'm uncertain about is how it will be when it's windy. As it is today, the roof and walls rattle and shake a lot when it storms.

Current open stable:
*The opening we have now is about 2.2 meters wide, and I think about 2.5 meters high (I know it has approved measurements at least). The new opening will be the same size.

*It is certainly 5 meters high to the ceiling inside the open stable.

*The wall on one short side does not go all the way up to the ceiling; instead, there is a gap of about 1 meter leading into the barn.
*The roof of the open stable is just sheet metal, i.e., it is not on any inner roof but just screwed onto the beams.
*The openings face west; we live on the west coast, and the sea is about 1.5 km away. So it can blow very hard. This is not something we can change since the open stable was made from an already added part of the barn.
*I have attached a very nice drawing😅🤗

My question:
How do I know how the force of the wind changes and is affected by an additional opening?

If I open another opening of the same size without covering the wall towards the barn, will there not be an enormous force when the air is pressed further out into the barn, and will this cause the roof to be exposed to greater pressure from the inside and potentially fly off?

If instead, you put up a wall where it's open towards the barn so that the air doesn't continue from the open stable more than through the two openings, will there be less pressure on the roof then?
I think there cannot be as much incoming air if there is counter pressure from the air inside the open stable.
Or would the openings and inner ceiling need to be at the same height in that case?

Oh my, I realize it's a messy description and I don't have a good grasp of the terms...
I have tried to read about how the forces work but still don't really understand.
I will also attach a very detailed and clear sketch 🫣
Can someone help me, suggest where I should turn, read? I'm grateful for any input. 👍

And yes, I need to change to two openings as a couple of the horses don't dare to go in if the dominant one is standing in the opening.

Hello,
We have a pasture shelter for horses with only one opening. I would like to make another opening. It will then be two openings on the same wall, with a portion of the wall remaining between the openings.
What I'm uncertain about is how it will handle the wind. As it is today, the roof and walls rattle and suffer significantly when it storms.

Current pasture shelter:
*The existing opening is about 2.2 meters wide, and about 2.5 meters high (I know it meets the approved dimensions). The new opening will have the same dimensions.

*It is probably 5 meters high to the roof inside the pasture shelter.

*The wall on one short side does not go all the way up to the roof; there is a gap of about 1 meter leading into the barn.
*The shelter's roof is only a metal sheet, i.e., not resting on any inner roof, just screwed onto the beams.
*The openings face west; we live on the west coast, and the sea is about 1.5 km away. So it can be very windy. We can't change this since the shelter was made from an already extended part of the barn.
*I have attached a very fine drawing😅🤗

My question:
How do I know how the wind force changes and is affected by an additional opening?

If I open another opening of the same size, without closing off the wall leading up to the barn, won't there be a tremendous force when the air is being pushed into the barn, resulting in the roof being subjected to greater internal pressure and possibly flying off?

If, instead, a wall is erected where it is open to the barn, so that the air does not continue from the pasture shelter except through the two openings, will there be less pressure on the roof?
I think that not as much air can enter since there is counter-pressure from the air inside the pasture shelter.
Or would the openings and the inner roof need to be at the same height then?

Oh my goodness, I see that this is messily described, and I don't have a good grasp of the terms...
I've tried to read up on how this works with the forces, but I don't quite understand.

It shouldn't let in much more wind. If you had another opening on a different wall, the air would pass through. For example, the wind shelters used for animals in a pasture have three walls.
