In the realm of complex systems there can be a large number of arbitrary properties that two systems share. Elegance is important in the understanding of negative entropy, as well as many other things. I do suspect that there is a direct connection between negative entropy and elegance. Given that a number of models of ENSO are not commonly accepted, and that negative entropy itself is not set on solid ground, I have a difficult time making a useful connection. Is ENSO an example of negative entropy?
