Which model is most accurate for Europe?

chstdu

@theradarguy The German Meteorological Office (Deutscher Wetterdienst - DWD) offers such statistically optimized point forecasts for about 5400 locations around the world as open data called MOSMIX. (Forecasting time step and update interval is one hour and the maximum forecasting time is 240h - https://www.dwd.de/EN/ourservices/met_application_mosmix/met_application_mosmix.html) The ICON model and ECMWF model are used as input.

Any idea how windy could visualize these point forecasts?
Maybe it could be added as additional model to the city weather details?

@chstdu
windy have available altitude data for any location.
Also model's surface height for any grid point.
The method described here:

@gkikas-lgpz Thank you for the information. These spot forecasts / city details seem to be the perfect place to also include MOSMIX. MOSMIX does not only adjust for altitude but takes into account a bunch of other statistical corrections and combines ICON and ECMWF, i.e., statistically the best of both worlds.

The Windy forum is not a place for advertising about your business. Just a place to talk about weather forecast.

I compared the forecasted and observed wind at some paragliding spots in Czechia. This was the result:

Arome, IconEu
Aladin (local model not available in Windy)
GFS, ECMWF

Raw data: https://pg.vrana.cz/meteo/

This matches my random observations. If IconEu and ECMWF disagrees then IconEu is usually right.

This site seems also interesting for such a comparison. I don't know it very well, but for Europe it provides 10 local forecast models with grids up to 1 km resolution...

The question was ‘’which model is most accurate for Europe’’, not which weather web site offers the greatest number of weather models.
The downloadable pdf in this document gives in particular the WMO scores for global models. Figures 13 and 14 compare the performances of these models like IFS (ECMWF), GFS (NCEP), ICON (DWD)...and more, for north hemisphere and Europe. And IFS is still the best one.
This comparison does not include the limited area models which are not really comparable with global models.

My response above just tried to help answer that very question.
I don't even know - and I don't care - if this holy web site offers the most models, but I still consider it interesting to better answer the main question in this thread.

How this site is interesting to answer the question of this topic? It does not answer at all.
Are you spamming only to keep Windy users out?

vsinceac

My answer was strictly about comparing forecast models; I never compared Windy (I love it) to similar web sites.
Anyway, as a moderator, if you would consider it as a spam, please feel free to mark it as such.
Nevertheless, I just tried to help Windy users to get the best results from Windy.

Each model has its strong and weak points, in short-term forecasts up to 48 hours let's say, for south-eastern Europe, like in Greece where I live, in wind (specially in gusts), temperature, humidity, cloudiness, the ICON-EU is real extremely accurate, as well as very good in heavy rainfalls such as storms etc, maybe the best I would say, it does not perform so well in weak local rainfalls, also for short-term forecasts up to 48 hours, the ARPEGE-EU and the NEMS4-12 do very well, NEMS4-12 also good for winds and temperature, but after ICON-EU, and the NEMS4-12 is underestimate the rainfall in this area of Europe, but NEMS4-12 have not so good performance through windy.com but from the parent page, because I think which has more options... for medium-term forecasts, ECMWF is one-way.
