Live weather is still inaccurate - 1.15.10 update did not fix bug

For REAL weather from the Model, yes … But for non-real weather , or user defined weather (maybe based on Metar like data from weather station “locations”) the concept of weather station may still have some merit.

A far more flexible system, than some “Preset” defining the same weather worldwide.

That concept is still around. That’s basically what Unreal WX and Weather Force do.

Unreal WX and Weather Force (and any other injector) only have one place to inject to ??
– the whole world ??

– so it can not be the same as say FSX, where different weather could be injected to different stations.

But not to stay too far off Topic … “LIVE Weather”

Even a broken clock is right twice a day.

That’s correct. When those injectors load weather into the sim, that weather scenario is rendered globally. Meaning if the weather station is reporting clouds broken at 3500’, that will be visible globally until you fly near the next METAR station, and then the scenario is reloaded with the info from the new METAR station and you’ll see the transition take place in real time.

I don’t remember that being a feature in FSX, but it’s been forever since I’ve used it.

Not “ALL” Broken clocks – :sunglasses:

Well, we wanted to look ad “live” weather here.
IMHO it is a good way to compare real data vs. sim data. The best way to do this is looking at wind speed and direction at the same place and time. In my example, shown in the pic of my last post around Corsica, there were very special wind situations at a small area, as shown with data from Windy. Well, I trust in the data from this web site, not only because of its name. Then I compared the data to that of the sim airplane, cruising around Corsica. For an easy access to the data provided by the simulator, I run Little NavMap connected with FS2020. So, I could compare facts, not impressions. In my observations, sim looks pretty in line with reality.
I find it a bit more complicated to compare clouds. So, in addition, I took precipitation. Also, in Windy, the precipitation is shown in a coloured scale in dBZ, which represents mm/h. It is permanently measured by terrestrial rain radar stations. So, I took a little flight from Jersey EGJJ to Guernsey EGJB at a slowly moving low south of Isle of White, with strong winds from west and some rain above the two islands. The wind was comparable to the real, but the rain was too much. It was more like a tropical rain, with clouds down to the floor, visibility less than 2000m. In reality it would be a bad idea to take this route with my DA40. On the tour, the rain stopped over the sea and started close to EGJB again. That was in coincidence with the rain radar. But, again, the rain was much heavier than the radar showed at landing, including low visibility. No way to succeed landing without the aid of the glass cockpit. At that point the simulation is pretty inaccurate. I finally moved more south of the low, where the wind was still strong, but precipitation and cloud weakened, with great areas of blue sky. My test route was from Tour LFOT to Poitiers LFBI. And, in deed, there was some drizzle rain at start, which ended pretty soon, in accordance to the radar, and the blue sky opened. However, the clouds were gone almost completely, although the satellite pictures of Windy showed some more clouds there. But, maybe, this pictures are an overlay of VIS and IR, which is not clearly comparable to visual examination in the sim. This time rain, wind direction and force was in agreement to reality, again.
With respect to a time shift into the future, I did no experiments yet, because I either take live weather and date, or define it all by myself. I find it confusing to use live weather and shift the time.
As I still have the problem, that I cannot start another leg from the world map, without loosing live weather, I do only few tests, since I have to restart FS2020 completely every time, when I want to see live weather. The trick to start with a preset clear sky and change to live weather at start of the flight does not work for me. This is a PITA!

I was just flying an ILS approach at KGCC using Live Weather setting. Wind was 3 knots headwind until I got closer to the airport. Winds shot up to 60 knots crosswind and was blowing me right off the localizer. I I did a go around and switched the weather to clear skies and landed. Weather is broken.

I have already documented the shift from advanced to the actual weather situation in the morning (somewhere between 0730Z and 0930Z), and here’s what happened today between 2003Z and 2010Z:

This is the situation in-game at 2003Z (screenshot taken at 1900Z, but was unchanged when I checked at 2003Z):

And this screenshot was taken at 2010Z (never mind the time slider, I had to shift it to daylight. It doesn’t change the weather situation):

For better orientation I have marked EDDH with a red dot. Look how the cloud formation stretching east-to-west is still affecting EDDH, while only 7 minutes later it has advanced to northern Denmark. That’s what is to be expected tomorrow, as the actual situation looks like this (SAT picture 2000Z):

Q E D !

Looks like the weather still was way ahead of its time at May15th at 0810Z. Notice the cloud formation well east of the adratic coast near the black sea, where irl it probably will reach in the evening.

And here’s what was loaded May15th between 0845Z and 0901Z :

Look familiar? Maybe because it’s nearly the same that was loaded yesterday at around 2010Z:

And it’s definitely the actual situation and was pretty accurate even yesterday evening. (as there’s actually a bit more high cloud coverage overhead EDDH in the SAT-image I marked the frontal convection in northern Denmark as it is probably hard to notice in the screenshot. And notice again the clouds over the adriatic sea and their actaul position at this time.

CONCLUSION
I guess it’s safe to assume that 12 hours of weather is missing completely in the sim.
The weather model from 0900Z onwards is obviously loaded twice, once around 2000Z the evening before, and again - correctly - around 0900Z. Now the only thing to do for ASOBO is to find the missing hours and inject them at 2000Z.

Seriously, I do not get why this seems so difficult for Asobo to resolve. Simply get the correct data from Meteoblue and put it in the sim? Sometimes I really wonder…

You may be oversimplifying things a tad, but I see where you are coming from:

  1. Fix things
  2. Profit!

But what exactly does that entail ? - many steps …

  1. Metro-Blue Runs a model
  2. Metro-Blue extracts data from that model, and makes it available to Asobo/Microsoft
    (I assume from what is said in the Q&A’s, that the data goes to Asobo in France ?)**
  3. Asobo further processes that data.
  4. That data is sent to servers to be distributed to MSFS users.

So a few questions to help understand how data can get old, or to far into the future prediction.

  • When metro Blue extracts the data from the model, is it CURRENT weather, or some future predicted weather. ?
    [ The fact that users can end up with future weather, would indicate that the weather metro-Blue generates for Microsoft is “Future” weather ? ]

  • How often does Metro-Blue update that weather, and how far in advance is it ?

  • How often does Microsoft collect that data ? Is the collection synchronized with Metro-Blue generating it ?

  • How long does Microsoft take to process that data. ?

  • When does Microsoft start sending new Data to its servers, and is that update time correctly synchronized with the the date/time that that weather is predicted for. ?

Personally, I do not have a clue of the answers to any of theses.
There may be others in the MSFS Community that do.

One would assume that Asobo has these answers, but are obviously under no obligation to tell us details.

So when we hear, “the real weather is fixed”, we really have no idea what is Fixed, or what a “fixed” state really is. Maybe that information is beyond our “Pay Grade” – literally.

At the end of the day, I would just like it all to work, as one would assume it should – but obviously it is not … so hence all the questions to try to understand what is going on.

THANK YOU to all those trying to analyses what is wrong, taking the time, and sharing it with us all.

Hopefully, sometime soon, all will be fixed, and we can move on, with Live Weather working correctly, and with its past failures becoming a distant memory.

Hello all.

very said to say again, now fly in Czech rep and Ostrava (LKMT), weather doesn’t corespond to Live weather (temp, press, wind ok) but clouds and rain doesn’t.

I FOUND IT NOW! :slight_smile:

I was think still about that idea about time zones and went again to Date/Time settings in Win. I click Synchro Time Zone and message about Failed was reported. BUT! Then in sim all comes correct with Clouds :slight_smile: I have now correct coverage. I think I’ll make tests and will see because I don’t think that this was really random about correct weather coverage loading :slight_smile:

If I can say my opinion, maybe really Live weather is working but our settings in Win are somehow not working hehe. Pls do all tests and report findings pls here.

Hope that someone somewhere did not intervention to set Live weather quickly to be right now :wink:

I had a look at mine just now and they appear to match! :slight_smile:

Wait a second, I uploaded the same one twice. Hang on.

Top is meteoblue.com, bottom is FS.

Hello,

thnx for feedback but sry, I don’t know what steps you did. I expect you can do this:

  1. start sim as usually and load Live weather.
  2. compare if it’s ok to reality.
  3. if not then try my sugestion about refresh time zone from Win menu.
  4. what happened then?

Pls also save my checks of your screenshots, so it’s ok for you, Live weather is accurate?
