[anemometrus]

there is an error in the nems model is it caused by windy or is it a problem with the model?

@anemometrus
This is probably a bug in the model.
You see in this thread (in French) that a similar anomaly but related to wind was already observed in the same location a few years ago.

There are four artifacts like this,
in a line just south of Malta
(latitude 35.5 North).....

According to meteoblue...

this is the southern limit of NEMS 4 model.

@Gkikas-LGPZ
Same in Sweden.

According to the NEMS domain displayed by Meteoblue in your screenshot, does it mean that Windy provide data outside the model boundaries ?

@gkikas-lgpz
In Meteoblue app the southern limit of NEMS4 is just through Lampedusa island,

But in Windy the layer limit is further south

Finally the issue is likely on the Windy side.
