The Takeaway
These vortices act like underwater smoke rings that transport heat across the planet, but they are usually too chaotic to model accurately. Finding exact solutions for their movement provides a shortcut to understanding how the ocean regulates the global climate.
From the abstract
We carry out an extended symmetry analysis of the multi-layer quasi-geostrophic problem. This model is given by a system of an arbitrary number of coupled barotropic vorticity equations. Conservation laws and a Hamiltonian structure for the general case of the model are correctly described for the first time. Using original methods, we compute the maximal Lie invariance algebra and the complete point-symmetry pseudogroup of the model. After classifying one- and two-dimensional subalgebras of the
