Comparative Structural Dynamics...

Chiral motion



What might be significant unifying junctures here in these two 'unrelated' considerations?
Any suggestions?

Erm.. you do realise that it's a myth that water drains in opposite directions in each hemisphere, don't you?

Neutralino .... How could this be a myth ??

If you drilled a hole right thru the earth and then let water spiral into it in a clockwise direction ... it would have to spiral out the other end anti-clockwise.

LOL ...

Speaking of sinks and drain water, yes - the Coriolis effect varies, usually in accordance with the structure and shape of the drain itself, so, that aspect of the oppositely rotating mediums is - or certainly can be, ambiguous...

Whereas, meteorologicially speaking, according to my google resources, the illustrated effect holds true for weather - hurricanes in the north and typhoons in the south....

"On the scale of hurricanes and large mid-latitude storms, the Coriolis force causes the air to rotate around a low pressure center in a cyclonic direction. Indeed, the term cyclonic not only means that the fluid (air or water) rotates in the same direction as the underlying Earth, but also that the rotation of the fluid is due to the rotation of the Earth. Thus, the air flowing around a hurricane spins counter-clockwise in the northern hemisphere, and clockwise in the southern hemisphere (as does the Earth, itself). In both hemispheres, this rotation is deemed cyclonic. If the Earth did not rotate, the air would flow directly in towards the low pressure center, but on a spinning Earth, the Coriolis force causes that air to be deviated with the result that it travels around the low pressure center."

Thank you for the reminder, Neutralino... While I re-submit the original issue....

Hey Greg when I flush the toilet it goes down clockwise, which direction does yours go?

A scientific experiment.

Hey ... Even tho we are on water restrictions level 6 here I just tried it. It didn't spiral either way.

Hope this doesn't mean I am sitting on the equator, because I would swear I'm south of it.

But I think Rascal is giving us the hint that we're off the track here. We don't want to wash the baby out with the bathwater ...

Dear Prof & Greg:

You are translating swimmingly.

The issue is now focused on meteorological conditions.

Rascal ... I am not sure what significance unification you are implying in your illustrations.

I agree with your description and explanation of the weather patterns, I think it is obvious enough to need no further explanation.

The second illustration looks like a digitally altered version of an M.C. Escher print.

Its peculiar in that it is spiralling through its own centre.

I don't see a relation between the 2 illustrations.

Can you provide some further enlightment ?

Good experiments everyone!

And yes, I agree that over larger scales the coriolis force is not neglibile as opposed to sinks/baths/toilets where you correctly point out that it is.

It would appear that the collectively contributing whirl is in synch (hic), and the comparative enigma is still with us in chiral effect and its noteworthy parallel...
