METEOBLUE vs. NEMS naming
-
No, METEOBLUE and NEMS are 2 different models. The first one developed by the Meteoblue company is a “consensus” model based on the average of about 20 models in Europe, and NEMS is just one of these 20 models. Further to the averaging, this Swiss company adds an AI processing on the Multimodel.
But the METEOBLUE model is a non gridded model. This prevents to make a weather maps from this model (weather map in Windy are made by interpolation of values at grid points). So METEOBLUE model is only available at point forecast and, as a map, Windy shows NEMS, one of the models which are a component of the Multimodel.
See what is this Multimodel

The METEOBLUE model is very good in many conditions particularly in mountains, but it is not so good at sea near the coast. I can explain it if necessary. -
@idefix37 Interesting, thanks for clarification. It is good to see new models and AI being used and provided to public.
-
@idefix37 thanks for your explanation.
Didn't know that Meteoblue is better in the mountains but not better along the coast.
Could you explain why? Would be very interesting for me, living at the coast of the North Sea.
Thanks. -
@Trallod
Meteoblue is quite good in mountain for temperature because this AI model takes into account the precise elevation of a location, better than the other models do.
Along the coast this model is good, but not so much over the sea at short distance of shore. I am sailing from time to time and noticed that Meteoblue forecasts give lower wind at sea near the coast compared to other models. Meteoblue explained to me that the model uses the data of the closest point of the point grid from each model of the multimodel. However near the sea shore it is the closest point but the one above the land which is selected. You know that the wind speed is lower over the land than over the sea due to friction. Why they do that ? Probably because there are more people on the sea shore than at sea near the coast. So they prefer to give a good forecast for wind and temperature too, over the land, rather taking data over the sea. If you stay ashore, you can rely on Meteoblue. Hope the explanation is clear. -
@idefix37 very interesting, thank you for your explanation. What you have explained is what I have seen since years on the maps of Meteoblue and Windy, that in certain weather situations on sea is less wind than on land along the coast. I know of course that this is impossible or at least not very probably, but now I know why. Thank you!

@idefix37 Would it be worth adding NEMS30 as another global weather map visually?
-
Personally I never look at NEMS maps, but here in Western Europe we have 7 models available in Windy plus Meteoblue.
-
I'm not sure I understand what you mean. The wind maps on the Meteoblue website are from many models but NOT from their Meteoblue model. The default map is from ICON in your area. As I explained above, this Meteoblue model is a non-gridded model and does not allow to draw a map. This model is only available as a METEOGRAM.
What I tried to explain is that the wind in meteograms on points at sea close to the coast is predicted to be lower than it should be because it is based on points on land. But not weaker than the wind on land. -
@idefix37 ah okay, thanks. Now I understood what you mean.
When I'm using the maps I normally use ICON D2. -
@Trallod
No, the maps shown in the Meteoblue website are the same as the ones shown in Windy. But Meteoblue shows just more weather models than Windy.
There is only the AI Meteoblue model (non gridded) which can’t be drawn as a map, both in Windy and in the Meteoblue website. -
@idefix37
Sorry for all the questions ... but it's worth to understand I think.
On the Meteoblue homepage I can choice a temperature map which is much more detailled, espacially in mountain areas, as maps in Windy.
Is this a map, based on the AI Meteoblue model?
I think this map is not possible to show in Windy, right?
It is because it is depending on altitudes, too? -
Could you give the link to this page ?

From your link it is clearly ICON which is the default model.
More precisely it is named ICON AUTO. I guess it means they use the ICON version which is available in this area. I made a comparison with other ICON versions. The map from ICON AUTO in this area (Switzerland) is exactly the same as the map from ICON D2. ICON AUTO seems to choose the best resolution for the location.
And ICON D2 is available in Windy on same domain
-
@idefix37
aah yes, of course ... I must be blind. :-D
Thank you very much for you help!
And yes, indeed, ICON D2 is availible in Windy, too.
Using the ICON D2 map mostly in comparism with the AI Meteoblue model.
Thanks idefix37! -
