Hi Graham,
Based on unisonal vortex mechanism, rings of Saturn are plasma tic polar vortexes, this implies they rotate around Saturn at high speed spin as flattened polar storms; in jet streams much faster than the fastest jet stream on Earth. The vortical force dynamics of the rings as a different state of matter interacts weakly with ice and dust entropies within the rings, may appear as standing waves optically, but they spin so fast that occasionally have formed some spokes within the flattened rings; flattened tornadoes driven by flattened polar vortexes. Imagine the force dynamics required to flatten a tornado; the rings are absolutely spinning.
Thru MHD dynamo effect on viscous matter, there should be huge electrostatic charge in the plasmatic rings (EM origin), strong electromagnetic storm coupled by electromagnetic fields, therefore has phenomenon of electrical discharge such as lightning (discharged radially as reported), abeit could be at different wavelengths and therefore do not interact strongly. The rings should be encompassed in larger nested plasmatic spheroids and this suggest there should be MF running through the rings. Just my ponders.
