Particle transport for probability of crossing the barrier #107

Closed DaniJonesOcean closed 2 years ago

DaniJonesOcean commented 2 years ago

In the PCA space, there are two wings and a bridge. One wing represents the circumpolar flow, and the other wing represents the gyre. The bridge is between them, representing the probability of crossing from the circumpolar flow into the gyre.

What's the probability of crossing from one wing to the other? Is it easier to go in one direction versus the other?

Ultimately, the circulation has to close, so it's probably equally likely to cross one way versus the other, but the crossing will happen at different depths (yay, overturning!), which may not be captured by this method. It would only capture those transformations happening in the upper 1km, which is okay.

Still, it could be really interesting to quantify this part of the transformation process. This might very well be a separate paper, possibly. That way we can focus on observations in this work.

Perhaps we could give Julia a try for this?

This is a nice idea for future work, but not for this paper. Closing it for now
