So the warm front is blocked by the wind from the other depression, thus creating the thin line of no wind, right ?

<p>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 ?</p>
<p>I've also checked with other models (NEMS (4km) and UKV (2km)) and it's the same thing...</p>
<p>Just so you know, I'm an engineering student, so it's not my main stuff by I'm still interested by the subject !

From the synoptic chart from the UK Met Office, the thin line in your picture corresponds to a frontal system. Immediately to the west of Ireland there is a cold front (blue line with triangles) and to the southwest of that, and inline with that, is a warm front (red line with semicircles).
