I successfully resisted the urge to call it Coriolis Farce.
Yay!! …
Coriolis effect
The observation that the deflection of objects or substances (such as air) move right in the Northern Hemisphere and left in the Southern Hemisphere.
Not north or south but flung off to the right or left according to which part of the equator… blah blah blah.
The effect is an hangover from the idea of a researcher who lived between 1792 and 1843. A lot has changed in that time. But not in scientific theory.
Was he such a giant or was he just making an observation?
Ask yourself how far can you fling air?
If you can manage to contain it in a vortex ring you can blow it quite a few feet. Obviously to make it go around the earth you need to insert the vortex into a tidal stream.
But by and large air or any gas will expand and contract according to pressure laws and according to the laws of thermodynamics any heat generated will be free to leave the system pdq.
Air is thus a BUFFER against any flinging!
But something IS obviously happening. Some perturbation of courses. Gyres -winds and the like do behave inexplicably in a manner so described.I am going to call it loading.Hurricanes are easily destroyed, for all their power.All it takes is a cross wind.Once enough moisture is removed from what is essentially an adiabatic system (an almost a self-contained event) the power to continue is removed.This happens without a cross-wind if the mass reaches a continental shelf or a significant shallows in mid-ocean. The force dies down considerably but it can rebuild once past the dam.I have noticed some strange behaviour recently on the computed runs for the southern hemisphere. Sadly I can't reproduce them with Gimp at the moment. (I seem to have a bug with that in Zorin OS.)What appears to happen is that if a sufficiently large amount of moist air reaches an already large cyclone from it's outer edges, an imbalance takes place in the core of the vortex.It splits up into two or three low pressure centres and these spin around one another in a contrary orbit. The so called "Coriolis" observation.It is nothing to do with earth's rotation. It is all an engineering problem of loading. It's the same thing that causes vehicles to turn over when they corner too fast. A complete change of direction induced by pulling gees.Normally the weight of a car is attracted to the ground. But give it enough negative "g" and it will have a centre of mass that describes a locus. The mass appears to follow another outer edge. It's actually following the new barycentre.The hurricane is not heavier where the moisture come from but lighter. And precipitation fals through it without affecting it but if the water remains a gas it is lighter on that side until rotation takes it to the other side, or spreads it.But it is spread all around the outside.Tropical hurricanes are wetted from the inside out. The so called warm core. They tend to remain symmetrical longer. And why shouldn't they?They operate within a wide band of tepid pressure that is usually 1016 millibars for a thousand miles north and south of the equator and stretches 24,000 miles around the globe.

It will affect it, eventually, if it falls on the windward side. As the storm runs over it, it picks it up again but because it will be a lot cooler than the original water surface…Well, you do the maths.In higher latitudes the air is a lot less stable it is full of unfallen rain and the remnants of older stuff. As a tropical storm becomes extra-tropical, it hits these pockets and elongates.By elongation I mean that the circle of a cyclone can become an ellipse. And the ellipse can extend into a trough of Low pressure.Or it can split up into more than one circulating current each of which moves around the others. Like twister sisters. Two or three (or more) tornadoes in close proximity will rotate around each other.As you watch the video, try and imagine where the energy is coming from. And what water sources there might be.
Hello dear,my name is QUEEN Oneil,it is a great pleasure to write you after viewing your profile at opera.com) i will be very happy if you can write me through my email for easiest communication and for me to send you my picture for you to know whom i am,remember distance or colour does not matter but what matters in life is love,my email address is (queenoneil41@yahoo.com),i will be waiting to hear from you,QUEEN.
I looked up something called Granular Impact. It is the mechanical principle behind sand traps and of research related to ballistic impact studies:Originally posted by Department of Physics and Astronomy, University of Pennsylvania, Philadelphia.:

All of this is a far cry from the NCAR explanation I found in the Encyclopaedia Britannica a long time ago.(Just as difficult to follow though.)
That was from:http://en.wikipedia.org/wiki/Granular_convectionMaybe I should have looked at this page first:http://en.wikipedia.org/wiki/Granular_materialDry as dust but it knocks seven bells out of the Continental Drift theory.How the force of impact is spread in equally matched particles: How jamming occurs at dams: With this latter phenomenon, it might be possible to kill yourself firing a shotgun where the shot is fused with wax. Various explanations have been proposed for that but I think that if there is a mechanism that moves the outer walls of the projectile faster than the centre, it could cause a blockage in the above mechanism if the barrel was long enough.Or maybe not:http://www.ar15.com/forums/t_6_1/368594_Dont_be_an_idiot_like_me__please_everyone_learn_from_me_.html&page=1
