Can we use this to also create isobars?

The same with what windy have? Can you point me to the right direction how this can be done?

leaflet-velocity does not have this capability (and as far as I know there are no plans to add it). Typically isobars would be implemented on the server-side using something like mapserver's contour capability (https://www.mapserver.org/input/vector/contour.html).
It would then be added as a separate layer in the leaflet application.

As an alternate I see there is a plugin for leaflet
https://github.com/equinor/leaflet.tilelayer.gloperations/wiki
It may do what you want.
