I've been wondering when someone would start working with something like this...

Interesting read.

I wonder if there are emergent principles governing the structures...and how intelligible those principles are without the aid of a computer.

I am linking what seems useful here (note some of this is math intensive):

Defintion and Properties of Lagranian Coherent Structures (this one has animations)

They don't look extremely different (actually, they look quite similar - but it's better to be more skeptical than not) from the movement of cyclonic and anticyclonic air masses in meteorology charts. It could be a case of scaled self-similarity, which would be reasonable given that both fields are based on fluid dynamics. The divide between self-similarity and uniformity could be seen as the divide between baroclinicity and barotropicity. Mbah, thinking about this only makes me feel like I should have gone for physics, as I wanted, instead of economics.
