All you have to do is moving the map under the picker !
This behavior was chosen because on the small screens of phones, it is not possible to get an exact position of the picker with your finger. You get more precision when dragging the map.

@ondrejspilka723 said in Meteogram wind speed doesn't reflect location altitude:

However, even ECMWF admits there're issues with 10m ground levels (see the article). Especially we will experience high inaccuracy for higher altitudes, stronger winds or complex orographies.

For mountainous areas, it is important to use a high resolution model if available where you are living.
A 9km resolution model like ECMWF model cannot perform in mountain. And worse, the orography model which gives to the weather model the terrain details is very coarse.

In the Meteogram, try Meteoblue which provides good forecast in mountain. It is available only at point forecast, but it includes a good correction of inaccuracies due to the altitude.

would it make sense to extend meteogram and show wind at altitude?

This is available with Airgram, useful for flying.

@ondrejspilka723
As there is no issue, try to understand the post of @Gkikas-LGPZ above.

And this one too:

@ondrejspilka723
Meteogram does not show the wind at 1000 hPa level, but at the location elevation that is the altitude amsl.

@Kim-Gebhardt

What settings are you talking about?
The main menu Settings on the right side should be saved, but all the others on the left are not.

@ondrejspilka723
There is no issue, no bug, nothing to fix there.
Meteogram shows the forecast at ground level (at 10 meters height ), at the location altitude.
The wind speed displayed on the map when you set the Altitude slider at 2000 hPa for instance, is in free atmosphere, not near the ground.
You might consider this to be an approximation, but all weather models works like that. This is NOT an error made by Windy.

@ondrejspilka723
Meteogram shows wind at ground surface.
Why do you set the Altitude slider at 3000m in your screenshot ?

EDIT: I see you posted several topic about the same question.
Please don’t multiply them !

@ondrejspilka723
The 10 meters are above ground (or above the sea level if offshore).
In weather stations the anemometer is placed at top of a 10m mast. And weather models compute wind at same height above ground. It is called the surface wind.
The Altitude slider gives the elevation as pressure levels.

As already said, Meteoblue uses the low resolution version of ECMWF. Same for AROME. They probably uses the 2.5 km version while Windy uses the 1.3 km version.
Then, as already said, “the reason for these temperature discrepancies is the way how the gridded data is used to get a local forecast. Windy makes an interpolation between the nearest 4 grid points while Meteoblue use only the nearest point “.
Looking at Hergiswil the max temperatures forecast for tomorrow give the following discrepancies:
Compared to Windy, Meteoblue display:
+3.5°C for ECMWF
-1.5°C for AROME2
+1.5°C for ICON D2
+2.0°C for UK2

You may also ask Meteoblue why they don’t show the same temperatures as Windy in their Multimodel diagram.
