Hi @Tokmurat, I would recommend comparing all available forecast models to get the most from our app, so you can get the real picture with reality. However, all models still provide only forecasts and not real-time weather.
If you look at Snow depth forecast by the default model (ECMWF), it is obviously wrong at Lago di Resia level which is surrounded by 3000m mountain tops. This model has a resolution of 9km and a coarse topography model. It is like using a camera with a low resolution: you would not get precise details of photos.
Try to use the ICON-D2 with a 2km resolution. It forecasts only 0,5cm at lake level, which is closer to the reality !
Hi, OpenStreetMap offers few versions of map. I use an app with a weather radar view and this app use a normal map with citi names in a local name w/o a translation. A version of map used in Windy is not clewer -translation of citi names are stupid. Sorry. o
You know that weather model data is delivered at grid points.
The distance between each of this points is about the resolution of the model. For instance 9km for ECMWF or 22km for GFS.
Then Windy interpolates the values at grid points which are smoothed to display the weather maps.
So, in mountains the temperature forecast cannot be very accurate.
In addition the model integrates a coarse orography model (terrain model) which does not accurately ‘see’ the altitude of a location.
The difference between the actual elevation and the model elevation is provided on the Windy sounding graphic at a location (long press on mobile screen or right click on desktop).
It explains the inaccuracy of temperature in mountains with global weather models. It is better to use high resolution regional models in mountains if they are available, for example ICON-D2 in this area. Try with it.
