The results indicate that the spores are yellowish, monolete, without perispore and bearing granular ornamentation on the exospore.They are bean-shaped in equatorial view and elliptical in polar view.
And remember, Saturn is oblate, so as the rings formed they would've felt a gravitational tug from Saturn's equatorial bulge, centering them right over the planet's midline.
They're much smaller scale the high latitude jets than the equatorial one, as far as in comparison to Earth these are massive, super-fast high-speed winds and yet they're just going back and forth.
