Realistic Dangerous Weather - Physics Simulation

That’s great to know. Btw, are you flying airliners or GA? as I heard that turbulence with GA is good/realistic, but that it’s the airliners that are like on rails

I raised this question again for the next Developers Update (Nov. 29th), specifically asking Asobo if they are planning to fix the lack of cloud turbulence while using real live weather! Hope you all follow up with them as well.

small good news from the Dev Q&A,
Seb admitted my observations that the general cloud density is too low in live weather, so they gonna look into this and see what’s possible.

In turn, when they increase the cloud density, the turbulence should get more noticeable.

However he didn’t admit the absense of general cloud turbulence
(which is the case, dangerous weather physics are still missing.)

Thanks for raising that question in the Q&A. Here is the corresponding bug report:

It sounded like they misinterpreted the question unfortunately. They were going on about general turbulence and suggesting what time in the year you should fly to experience turbulence and completely missed the fact that the question refers to cloud turbulence specifically. This might have to be raised again.

Oh noooooooo! This is a very simple question about cloud turbulence! How can they misunderstand it?! I have to watch it!

Seems like Seb did answer it and he said he will look into it for the next Sim update! Fingers crossed, they will figure out how to make the real weather clouds denser which should hopefully result in more realistic turbulence!

I did not know there is a link between cloud density depicted in sim and cloud turbulence. I thought the density part of the question was only about how it looks visually going through clouds. Are we saying that if I use a weather preset and set clouds really dense that there will be cloud turbulence?

Edit: Tested this with presets and clouds at max density provides no turbulence when flying through it in a 172.

Can someone please tell Seb this and show him?

Interesting! There are other tests that showed the density does make a difference but I have never tested it before because the issue to me is bigger than that! The clouds should cause turbulence and they do in real life, only if the particle movement is modeled correctly! Currently it’s not! Seb is saying that he got significant turbulence going through clouds, but that has never happened to me even in stormy conditions! Sure, I get wind and updraft/downdraft turbulence but none through the clouds and that’s bad for a Flight Sim!

I don’t know, listening to him it sounds like he was confusing cloud turbulence with general turbulence in stormy conditions which is evident by what he says towards to the end about what time in the year you should fly in order to get turbulence. But if they are just going to let live weather clouds go to the max density similar to what I can set in presets then that will not do what we asking for I am afraid. Hoping I am dead wrong.

Saw the stream. A bit disappointed when they are finally asked about the lack of in-cloud turbulence, they almost misunderstand the question…

There is no in-cloud turbulence in live-WX.
Yes, there are (endless) updrafts / some downdrafts, machanical turbulence, and ultra-frequent-micro-gusts causing a turbulence effect.

But no turbulence inside CBs, at the buttom of cumulus clouds etc.
That the devolpers themselves haven’t noticed this is a bit concerning imho.

That the severity of the turbulence relates to cloud density comes from the video where Seb adjusts some WX-presets, and he gets severe turbulence with max density. Problem is (as said by many others) that live-WX doesn’t seem to be anywhere near these density values.

The lack of proper turbulence and in-cloud turbulence is the thing that really dumbs down msfs atm, imho.

Correct me if I’m wrong, but denser clouds should cause more turbulence in reality, there is simply more energy, up & down drafts going on than in small ‘‘seethrough’’ clouds. What Seb was describing is the fact that a heated ground related to a cooler air temperature can cause turbulence as well, even without any clouds.

I made a big test a while ago, but I didn’t retest ever since.

I bet you are only flying airliners. I fly mostly GA and get turbulence when I enter clouds with live weather (don’t use presets), especially clouds with rain. Try it with a GA aircraft.

“We” have tried.
Last time I tried, I searched for the most severe WX on the globe - live WX. From South America to Japan.
Flew my mighty C152 through the “thunderstorms”/CBs - no turbulence.
Updrafts for miles…

What you might refer to are wind gusts. But those only yaws the plane ultra-fast : no roll movement, no abrupt up-/downdrafts, no “vacuume” pockets etc.

Those wind gusts are all over the place, and not related to clouds at all.

I did a test, using cumulonimbus Floyd Epic Clouds preset, default clouds density is 0.08. Flying through the clouds with the Pilatus that is a light plane, there are no turbulence. Setting density to 5 (max), same, no turbulence (clouds look like volcanic eruption). So my guess (same as in other posts) is that the turbulence we can sometime experience flying through clouds are coming from the ground or from gusts injected by Live weather but are not generated by the clouds themselves.
In SU6 they made an adjustment to the cloud density effect on the aircraft but it was to fix a performance problem with the aircraft, it did not impact the turbulence within the clouds.
Continuing the discussion from [RELEASE] Release Notes (1.20.6.0) Sim Update 6:

Maybe they’ll make some adjustments to the density in the next SU15, it will improve clouds depiction that in many cases are too transparent in Live weather for sure but I doubt that it will fix the turbulence issue within clouds. They should find a way to link the cloud density (or another parameter) to a turbulence value or correctly model the up/down draft flows, air flow turbulence generated within the clouds.

I do! But clouds sure cause a lot of turbulence for airliners! You can simply just a few youtube videos. There is absolutely no movement associated with Live Weather clouds in the Sim for airliners right now which is very unrealistic.

You are absolutely right! The sad thing is clouds did have turbulence before SU5! and lots of it! Right now there is none, and you correctly stated that all the turbulence is associated with up and downdraft and wind gust! None of it is associated with the clouds (cloud particles) themselves!

Asobo please look into this. Even FS2004 had this depicted correctly and much better!

Regarding that point, I am not sure if clouds turbulence have ever been implemented in MSFS. Maybe what you experienced before SU5 were over simulated turbulence present everywhere (not clouds related) that many complained about. They decided to temporally desactívate them meantime to re-implement with a more accurate model based on heat coming from ground, what they did.
