You'd likely be wrong. (and most folks, including the RN's naval gun designers would have thought Paris to be a "High Latitude" location). The Coriolis Effect certainly "increases" with distance traveled, but it no less alters the direction of travel of objects over short ranges, where the movement becomes imperceptible except with scientific measurement). The easiest way to observe Coriolis is with every flush. Unless you've magic plumbing fixture, yours displays the familiar rotating swirl (which in the Antiposes is reputed to be in the opposite direction) Almost every drain (other than close to the Equator) will display the circular motiuon (generallly covering distances far more than your silly (Numbskull and dumbass) "few centimeters". Amost every molecule travels a fair distance as it descends in the classic circular path.

The answer according to leading researchers in the USA is winter - EVERY year Now we expect you to weasel, lie and obfuscate to avoid admitting you were wrong but dont imagine you are fooling anybody, except perhaps for yourself. Ignorance is pardonable and fixable but stubbornly adhering to error is rather sad. Keith

It's actually just past the halfway point as latitude goes, being at 4852' north latitude. > The Coriolis Effect certainly > "increases" with distance traveled, but it no less alters the direction of > travel of objects over short ranges, where the movement becomes > imperceptible except with scientific measurement.

Yes, but not because of the Coriolis effect. As water moves towards the drain, it must conserve any angular momentum it already has, and as the circle through which that inertia acts shrinks with the movement towards the approaching drain, angular velocity increases. Thus, imperceptible angular momentum in a large sink full of water can produce an obvious swirling as the water goes down the drain. -- Transpose mxsmanic and gmail to reach me by e-mail. |
