they are clearly going for something far more advanced with their CFD atmospheric airflow simulation. The problem is, the proximity airflow simulation particles are not interacting with the clouds.
If MSFS are working on this and will improve the turbulence, that is great news
Yep, the flight dynamics is light years ahead too, especially during flare. And inertia of a heavy aircraft felt like never before. DCS and X-Plane will never catch up.
Sorry but did I miss something? I didnt have this āTurbulenceā slider not in my Assistant Options?? Where is it? I search for it in the search field but didnt find it
Included in the Beta. Assistance Options under Piloting.
To the others: Sure MSFS has its quirks and issues. But thereās no way previous sims could come close to what we have ānowā. I mean we get virtually some form of monthly update. Not that I ever used XP and P3D, but I know generally it takes quite a few months between new versions or releases. For whatever reason people back then seemed to be a lot more patient and understanding compared to how people react regarding MSFS and Asobo. Iāve seen it mentioned on here multiple times from experienced users on both platforms that youād need to spend hundreds of dollars in additional addons and programs to get anywhere near being able to compare the two (XP and P3D). I believe it. There may be one or two items that I miss from the past that arenāt up to the same level in MSFS but none of them are enough to make me stop using this platform. It offers way too much to ever feel the desire to downgrade, thatās what youād be doing, and with constant development that is only 3 years into a 10 year obligation, thereās no argument to be had. The changes we get for each SU or Beta every month or so would take 6+ months to a year for XP or LM to do.
Source: Simming since FS2002 and have wasted so many hours/days using different programs and tweaks to get everything as realistic as possible in regards to aircraft simulation, traffic, weather, scenery. MSFS takes the cake before the race has even started.
As far as development, I just thought of this comparison, itās like taking a peddle car and matching it up against a Mustang.
Ok thx I didnt have the Beta 
Well, i think we are all here because we feel potential in this flight simulator and for some has felt like that since it got released 2020 and also wished for more realistic turbulence inside clouds. Iām looking forward to the 20KM aircraft CFD that is in R&D stage as they said in one of the latest Q&A. But since they limited the airflow from thermals to the cloudbase and those mountainwaves are now also limited to not be able to reach higher altitudes. Now we have complete calm air above the cloudbase where the air should start to be turbulent because of the unstable mixing air inside those clouds. Hope they add that soon. That would make the air inside comulus or Cumulonimbus clouds feel more realistic. As it is now we can fly right through those types of clouds without notice or fair of danger. To me even add some unpredictable air movement would make it more realistic than it is now. Because turbulence is unpredictable and impossible to recreate 100% realistic. CFD in my opinion is the closest we would get if they are able to model ālarge eddyā. If we get that i think we have as close to an air/fluid simulation as possible. Then they donāt need to add many different simulations because the whole fluid is simulated. But that feels really far away because if they would simulate air like that we wouldānt have air that matches those METAR readings if they choose to use that system at airports. Because we canāt have fixed air velocity to a METAR value and at the same time simulate a fluid dynamically. They could inject the velocity in the simulation as an initial condition but the output would be unpredictable as air is in reality. The question is how many would accept that the air doesnāt match the MEATAR 100%? The accuracy to real weather limits the weather to behave like real weather. Well, hope to see some turbulence soon though even if itās not 100% accurate modeled as the real turbulence 
I will show why i think the aircraft CFD is really nice feature and why i feel that should be used for the atmosphere as well. It actually creates eddies in real time. I need to create a video for it and it takes a bit of time.
As iāve said the only issue i see with it is the need of flight simulator community to have air that matches METAR spot on. That āneedā actually makes it not possible to simulate airflow or any type of weather perfectly.
Here it is. Notice when i increase velocity in wind the more turbulent the air gets to the right of the rudder after the rudder has blocked the airflow. And thats happening in real time. Really impressive i would say. Iām really looking forward to 20KM aircraft CFD.
Iām not in the beta butā¦ Has the CFD model even been applied to all the aircraft yet? I donāt think it has. Maybe everyone should try the C172 before claiming theres no turbulence. Lately Iāve been thinking the roll aspect is just too much and Im looking forward to the slider.
Also - not all clouds/weather will have tons of turbulence.
Nope it has not. Itās not even active on the a320 but in the devmode we can activate it on all of the aircraft for a visual but it has no effect on aircraft it needs to be set in flight_model.cfg to have effect i think.
I know of the default aircraft the c172 g1000 has it and all of the helicopters.
Thatās very interesting, itās the A320 I am using where I feel no turbulence at any time. But I just had a look into the flight mode.cfg and canāt find any reference to turbulence, but there is reference to other flight dynamics - see below I have reproduced the cfg
Now we have complete calm air above the cloudbase where the air should start to be turbulent because of the unstable mixing air inside those clouds. Hope they add that soon.

Here is a link:
By āone of the latest Q&Aā, do you actually mean one of the Q&As before the atmospheric airflow simulation was actually released to the public?
Iām really not sure what youāre trying to say here. I have shown multiple times that the wind values on both the manual preset page and from live data like METAR\Meteoblue are the starting point of the atmospheric airflow simulation.
Apparently many, because thatās how it currently works, as Iāve explained in great detail. Both live and preset wind data are the starting point of the atmospheric airflow simulation, after that, the particles can change speed as they interact with the environment and each other, as you can clearly see in the visualization and in the weather debug window.
I see less of a āneedā from the community for METAR than I see people falsely attributing things to METAR and spreading incorrect information about how the weather and airflow simulations work. But thatās just a personal observation.
Hereās a quick example that took me only a second to find. I am at Lake Tahoe. METAR is saying 15-23 knots, yet the the air that is interacting with my plane (the atmospheric airflow simulation voxel) is actually 29 knots. That is higher than what METAR was saying. Why? Because METAR was the starting point. The airflow simulation particles sped up as a result of the simulation.
One more example with the airport in view:
Hereās an example with a manual preset. I have the wind set to 8 knots with no gusts, yet the ambient wind speed at my aircraft is 19 knots and gusting because of the environment. The particles bounce around, theyāre pulled up and down by heat from simulated solar radiation, they tumble, they swirl. It can be very unpredictable depending on the location, terrain and time of year.
Iām not commenting on how it is coded: that I donāt know, but in my opinion, the turbulence slider should never alter the turbulence, whatever the weather, live or preset.
The slider should affect how much the turbulence affects the aircraft
That seems to be how it currently works. Looking at the weather debug window and the visualizations, the slider doesnāt seem to affect the atmospheric airflow simulation.
Thatās exactly how it works.
The āsliderā doesnāt actually affect the world turbulence, it only controls the affect the turbulence has on your aircraft.
Many thanks!
They told that it doesnāt affect the atmspheric behaviour at all. Itās like a filter.
Yes, Seb mentioned the full CFD simulation in November last year.
Well, maybe i missunderstood something. But he also mentioned 20KM aircraft CFD that they worked on also before the visualization tools were released. When Seb showcased the thermals and stuff.
Well, i try to not give missinformation. I just try to tell my experience after testing. For example the windspeed canāt go lower than what a METAR says at airports. That to me is a wind that canāt flow as air does IRL. Itās manipulated to be at or above the mentioned winds reported on a METAR. Same with wind direction and gusts. If METAR says wind 10 gusting 20 the wind will be between 10 and 20kts. In reality it could be between 0-20KTS. Wind speed mentioned on a METAR is average over 2 or 10 minutes period of time. In the sim we get an average that is higher than what is reported on the METAR as it is now. And if you check the dev tool you can see the average windspeed besides the windspeed and it says the average is the METAR meantioned winds but how can that be a correct average when the windspeed never goes lower than the mentioned average value?
Well i just wanted to tell that if we want a full simulation of air we canāt have air that is fixed. Then if Asobo want to have the air fully simulated itās up to them to decide
And iām not argue because i know that the winds are important to have correct as METAR says to be able to plan runway in use. But get a full simulation of air is impossible if we needs the air to be fixed. Well, you donāt need to listen to my information if you not want to though. I hope Asobo get some turbulence inside clouds and some CAT above clouds in the future I like that they working on the air. I think it can be improved as long as i live and also after and i know it will be impossible to get in a 100% perfect state.
Could it be because of nr 6 on this page?
Seb also spoke about this, and had to laugh when people started to complain about too much turbulence in the sim when the sun kicked in in summertime.
Well we have updrafts caused by thermals none says those not exists in the sim. We also know those is less in winter. When looking at a radar and we see heavy rain we should have more downdrafts, I have not tested if that is the case but flying inside heavy rain doesnāt cause much downdrafts what i know. But we do not have mixing air that is unpredictable. That to me is turbulence. The thermals under clouds should be laminar/more predictable but that is not called turbulence because itās laminar flow of rising air. Near the friction layer there should also be turbulent flow and that we have with the mechanical turbulence caused by the uneven terrain and obstacles on ground.
Whats missing is the mixing of air inside clouds that cause air to be turbulent. Hope they are able to implement that in as realistic way as possible, mixing of air due to the temperature, pressure and velocity changes within clouds
Would also like to see mixing of air between layers above clouds that causes CAT.
I know turbulence is a really complex thing to model. But i feel this sim has potential to make it really realistic in the end with the CFD model in use Itās actuallly stands for fluid simulation. And that CFD model can be improved and be more detailed and accurate in the future. But adding values into that model to fix the air into a state iām against. Because that limits the simulation to be a simulation. Same with the visuals of weather actually. That we can notice more because we can see when the weather doesnāt behave like weather.
I just had the chance to try a test version of CFD on an airline (A320 derivative) with my motion platform, I thought it was very encouraging, it felt good and realistic. Flying into CB I encountered severe turbulence and, as in reality, the aircraft was difficult to control with autopilot, but if I folowed the FCOM and disconnected A/T and used CWS, the aircraft was more controlable. Given this is early days, this has made me feel very encouraged.
But with this, we definitely need the wxr radar to, as in real life, avoid CB
