It's a wind map from the ICON (13km grid) model of the Atlantique ocean of this 7 July 2023. I get that there's two depression near each other interacting but how there's only a very thin line as the resulte of the interaction ? If it's not an artifact from the model, why is it SO thin and not align with the center of these depression ?
I've also checked with other models (NEMS (4km) and UKV (2km)) and it's the same thing...
Just so you know, I'm an engineering student, so it's not my main stuff by I'm still interested by the subject !
