Saturn's hexagon or how at home to reproduce the experiment of scientists from Oxford University
Strange thing, read Wikipedia:
“Scientists at the University of Oxford were able in laboratory conditions to simulate the emergence of such a hexagon. To find out how such a formation arises, the researchers put a 30-liter water tank on a rotating table. She simulated the atmosphere of Saturn and its usual rotation. Inside, scientists placed small rings rotating faster than capacity. This generated miniature vortices and jets that the experimenters made visible with green paint. The faster the ring rotated, the more the vortices became, causing the nearby stream to deviate from a circular shape. Thus, scientists managed to get various shapes - ovals, triangles, squares and a hexagon. Scientists compared the experimental data with what is happening on Saturn and suggested that in its high northern latitudes, individual jet streams are dispersed right up to the speed at which something like a stable wave forms - a planetary hexagon. And although the study did not reveal the origin of such currents, it showed why the entire system exists stably. ”
And now let's recall the hydrodynamics and what the solution (angle) of a standing wave is equal to, correctly 120 degrees. Now we move the waves into the system (cylindrical, toroidal) of circulation and we get that with the simplest packaging we will have 6 peaks.
And now we will not repeat the complex experiment of the "British scientists", but artificially reproduce the hexagon in a whirlwind at home. So, we need a wide glass (you can bowl), water and a fine dispersion (tea leaves are suitable ordinary tea) and a teaspoon. Stir intensively, carefully remove the spoon and wait for the rotation to stop. At the bottom we will observe how the tea leaves gather in the regular hexagon!
