This short paper discusses the fact that one can have turbulence,
in the sense of chaotic vortex motion, without an upscale or
downscale cascade of energy. My student Stephen I. Thomson and
I encountered this situation in
our work to model the ‘unearthly’ jet system on the planet Jupiter,
the straightness of the jets making them very unlike
the meandering jets in the
Earth’s atmosphere and oceans thanks to the very different conditions
on Jupiter.
