When switching models, the display value of selected layer (e.g. wind) is one-switch behind

  • "As shown of screenshots posted above, values are correctly displayed for ALL models (including MeteoBlue)."

    -- you are right. Unfortunately I can post equal sequence of images that shows that meteoblue data is not displayed (I mean the whole map, not the one displayed number). Instead it displays GFS or ECMWF.

  • I repeat, models are only listed on UI when they apply to currently selected map coverage (as not all of them are global).

  • Ok. If I start windy, click on a map to select location and switch models in the bottom-right, it seems to work. If I then click on the yellow arrow to expand the bottom panel with meteo info, the value on the map disappears like you say, so I cannot compare. But if I start windy, go to the search bar in top-left, choose some previous location, the bottom meteo panel is expanded automatically but the value remains displayed on the map (unlike in the previous case). Now if I switch models using their labels below the meteo panel, the displayed value on the map gets confused - it may seem to work but you quickly discover that the values are wrong, because it is possible to get 2 different values for the same model depending on which model was selected previously. I am not sure I can give any more info to replicate the error. I can make a video of the whole process I guess, if anyone is interested. The same error is apparent which other layers (clouds) where different models often give different numbers so it is easily visible.

    yes, I know about model availability, bu I sense that meteoblue is in some ways special - for example it cannot be selected in the "meteogram" panel (instead of "basic")

  • Nope, MeteoBlue model can be well selected on meteogram:

    I apologize but I couldn't help more on this... You should wait for some more pertinent advice from Windy support.

  • I meant the "meteogram" info, what you show is "basic". My meteoblue is grayed out and cannot be selected, which probably is not a bug but led me to believe that it has something to do with why (for me) meteoblue is not displayed correctly on the forecast map (which I believe is a bug).

    When you select NEMS for a layer on your screen, it shows NEMS model which is a model from Meteoblue (In fact an American model modified by Meteoblue). But in the Meteogram it is (probably) a different model called Meteoblue AI. So there are discrepancies between map and meteogram when selecting NEMS/METEOBLUE.... according to some explanation given by Meteoblue here:


  • On NEMS/MeteoBlue stuff, there is maybe kind of language abuse on Windy UI...; afaik.:

    • NEMS stands for "NOAA Environmental Modeling System"
    • MeteoBlue computes its pretty accurate local forecast model (numbers afrer "NEMS" are for coverage) from a mix of different models (including NOAA's NEMS model) and additional data sources (e.g. more accurate local topography)

  • Sailor

    There is no language abuse from Windy. Even if NOAA developed NEMS and uses it in GFS core, on Windy the data shown by NEMS layer are provided by Meteoblue.


  • @hookxs, you should maybe join this thread, where a guy (who knows well Windy :o))), says: "Meteoblue is not NEMS. Those are two different datasets"

    @vsinceac @hookxs @idefix37 Hi there, I could replicate this and there seems to be some minor discrepancy. We will investigate. Thank you for reports!
