Before there is motion, there are waves. The waves begin at the aperture, they cannot begin in the fluid. At the smallest disturbance in the energy field, there is an angular imprint on the soon to be vortex, an imprint that detemines the poles of the filaments. The angular disturbance is the instigator of the spin of the vortex.
Are you certain this is unrelated to the Gravitational field spinning between two poles?
Water waves react to frequency and amplitude, plus direction?
Only if the Earth was not spinning would gravity be acting ninety degrees to the center, it us always either 90+/-. There is no thing such as 0 rate in our system.
Everything is always moving, and direction is spin dependent, I think......in a passive locale. (tub, drain, water,)
