Based on a comment, I'm now plotting the Rossby number snapshot as $Ro/Ro_h$, which makes it much easier to see the dynamics:

@wenegrat I was wondering if I could get your opinion on some plots of (what I think are) CSIs.

This plot is the same that's currently on the paper, except that I'm plotting more downstream locations and also plotting vorticity into the page:

This is another plot that's in the paper, but with similar changes made.

It seems to me that just plotting the vorticity, things look a lot more like CSIs, but I'm not sure because one thing that I got from our last talk is that maybe I'm already biased with these plots and may be seeing things that aren't there. So it'd be nice to hear your take

Also, we need to keep in mind that some of these bands that appear on the vorticity also happen for cyclonic simulations, so really we should be looking at the vorticity bands where there's negative PV. For example, here's an anticyclonic simulation:

and here's the same simulation, but cyclonic

So I think we need to be focusing on the vorticity in the thin BBL wake that has negative PV.

Yeah, that's tricky. The banded shear structures do look CSI-like, but possibly they could be other things such as internal waves, or something about the tilted-eddy structure. That they persist in the cyclonic headland is also important, although there as well there is a low-PV layer (formed from the interaction with topography in the recirculation of the lee of the headland?).

By low-PV do you mean negative PV? Or negative-and-zero PV?

But I think I understand what you're saying, and yes, there's also some negative PV in the cyclonic wakes due to the recirculation, although it's obviously a much smaller region. It does seem to act to mix PV and create regions of zero PV, which maybe muddies the waters a bit; no pun intended :)
