Check out this obvious METAR cloud. See how it’s dense and circular? So obviously METAR… Okay, it may be in the middle of the ocean, but how else do you explain this? Okay, storms may usually be circular, but there must be some other explanation involving SU7… Okay Meteoblue storms take the shape of real life storms, which tend to be circular and we’re obviously limited by the resolution of the weather grid and the voxel engine… But maybe it could be a METAR station on a boat being driven by Asobo to mess with us?
On a serious note. Between SU7 and SU10 there was a serious problem with the weather engine not properly generating overcast skies from Meteoblue data. In SU10 they made changes to the cloud generation algorithm to ensure that overcast skies are where their Meteoblue data calls for it, which looks like these clumps of clouds (ie: storms/overcast) that are being posted. What matters is how often the clouds actually match METAR. It doesn’t take much testing to find that it often does not match METAR and they pass right over METAR stations. Meteoblue has a pretty good weather model, so of course it will match sometimes, but the fact that it doesn’t always match is a pretty good indication that METAR clouds (or the lack thereof) are not replacing Meteoblue clouds.
Not that this will matter, but another important point is we’re used to seeing clouds from below, not from the heavens. Even most pilots don’t see clouds from the heights we can get to in seconds in development mode, and real life clouds don’t have to worry about pesky things like vram and FPS… That’s why I try to look at the clouds from more realistic angles.
