Forgive me for sticking my two-pennorth in, but aren't all those phenomena
attributable to the Coriolis effect?

In other words the spin of the earth is moving all the things loose on
it?

It is attributed to it but only because the platitude is the only
suggestion that tickles the ears best. It's not verifiable and the
northern cyclones run the wrong way for that explanation (or is it the
other way around.)

In essence, the planet's rotation sets up this directional acceleration
effect, which is also thought responsible in part for the complex currents
in the Earth's core which give rise to the drifting magnetic poles (and the
occasional reversals thereof).

The ocean flow in the N Atlantic basin is some 30 million cubic metres
of water per second through the straights of Florida and 80 million
past Cape Hatteras. (According to the 1998 Encyclopedia Britannica.)

If Coriolis' "force" can do that then it must have the force to do it to
aircraft of insects or both?

And it should be noticeable to fairly mobile objects on the surface
-such
as us. Shouldn't it?

In the dim past we calculated the effect on a
steamloc going fullspeed north in Norway.
The coriolis force on that loc was about 100Kg
(or about 1000 Newton).
So thats very small for such a heavy loc.

What is a steam loc?

It seems to me that you can balance a bottle on its head just as easily
on the equator as you can in the poles, given a stable platform.

And that there is no apparent difference in the ease of it for any
location and it doesn't make any difference how large the bottle is.

Am I being extra specially thick today or am I correct?

I am not saying that there isn't an effect and the one known as the
Coriolis effect doesn't exist, just that it aught to be called
chirality the same way that all the other exhibitions of the effect are
called chirality.

But I have an hangover and can't think of any other examples at the
moment so help yourself to a search.

I have read too that this effect is not reckoned to be a force but I
can't get my head around how it manages to shift major currents like
the surface wave called the gulf stream. Not only that but add to it
from time to time with the elemental forces of tempests.

Abracadabra.

The loc is short for the thing pulling a train.
The coriolis force only shows when you are moving north/south,
so that the effective distance to the earth rotation axis
changes, moving east/west produces no force.
So several tons moving north at about 100 km/hour gave ~1000
newton force .

From what I have read - and I am NOT knowledgeable in this - chirality
is not the same as spinning or spinning forces.

Chirality has to do with left- or right-handed things - like screw threads
and isomers of certain chiral molecules - like sucrose, for example.

If you wanna know more, I refer you to a poster on sci.physics, who goes
by the name of "Uncle Al", Dr. Alan M. Schwartz. He is practically
obsessed with the subject and frequently held forth on it when I used
to read that group*. He's an "organiker" (an organic chemist) and he
_really_ knows his stuff.

And it's just a coincidence that all creation except the oceans exhibit
this effect IN THE SAME HAND.

He's a prick and a racist and really knows how to tell people to
Google; he is not interested in anything remotely resembling a
discussion. The purpose of Usenet is discussion.

When he can get his head around that idea, you will know he has been
able to remove it from his arse. (And the swelling will have gone down,
somewhat.)

With all due respect to Mike Tullet, IIRC the Encyclopaedia Britannica
avers the effect is not a force.

And a steam loc is a locomotive -or loco for short; they weigh
something in the region of 200 tons depending on the type. (With a full
load they can weigh a lot more of course. And are then known as trains.)

First time I've heard it called that. It's a loco, believe me!

The Coriolis force acts whatever the direction of movement..
At 100 km/hr the Coriolis force is about 0.003 times the mass, at
latitude 50°.
