Possible causes for the behaviour of air pressure systems over the North Atlantic. …
Air much more so than water is a perfect fluid. And water is considered a fluid so near perfect that there is no real difference between it and the ideal.
Anyone who has tried to make a floating crumb move around a cup of water by turning the vessel will hae realised without knowing it that this is so.
If you turn the cup, the water will not turn with it because its viscosity is too low for any friction between the cup and the water. The connection breaks and the cup will not drag the water with it. The phenomenon is called "shear".
So how much less impact can a stream of one gaseous system have on another? And don't forget that shear is a meteorological term. Slightly different meaning to the one used in fluid mechaniocs but how can there be one law for the engineer and one for the prognosticator?
But that is another story.
I have wracked my meager resources to try and come up with an answer to the riddle of why there are relatively low high pressure areas and high low pressure areas when there is an imminent danger of volcanic eruptions.
All the more difficult as there are no volcanoes on the Atlantic rim.
But the middle of the Atlantic is alive with them. And the confluence of the major weather fronts in the North Atlantic tend to happen over the Mid Atlantic Ridge.
A lot of theorising concerning the nature or hiatus of the so called Global Warming (herinafter called Glowballs) concerns the behaviour of the Arctic Ocean.
The Disappearing Ice effect.
The temperature of the sea in the Arctic seldom rises or drops much from freezing point. Cold water drops deep into the basin before it can freeze. Sea water thrown onto the ice, of course, can reach quite low temperatures if blown on by storms. Ice so formed is blue with the salt it contains. This later falls through the ice and if it mixes with ordinary brine becomes dense enough to fall to the bottom of the ocean. It will not be much more than 4 degrees C and likely as cold as minus 2 degrees C, which is about as cold as the Arctic gets.
So you see the Arctic Ocean is constantly being mixed from top to bottom. In winter it is fed ice directly from frozen rivers all along Canada and Siberia. These form bergs that drift south out of the Arctic via the Davis Straight on Canada’s east coast and into the North Pacific through the Bering Straight.
More water leaves via the channel between Greenland and Europe but warm water enters the Arctic over the top of that.
Now here is the interesting bit:
When the pressures are anomalous as described above (a Negative North Atlantic Anomaly) convergence from tropical storms in the mid Atlantic runs directly north from the centre of the ocean and enter the Norwegian Sea, often going well along the Siberian coast before running ashore.
The only explanation that appears to make some sense in all of this is that there must be an extremely large amount of heat being evolved in the vents deep under the North Atlantic. There must be enough to make it appear that the global conveyance of cold water from the Arctic has ceased in large measure.
For this to happen requires that the lunar phases must be supplying a great deal of pressure to the strata in the regions where these vents exist. These vents too have to have an organism in them supplying, in exchange for this pressure, some form of biosynthesis that must be producing the heat.
It is known that under pressure some rocks can evolve light.
So the biosynthesis does not have to be that radically different from our understanding.
Well, you should be able to see where this argument is going. All didactic nonsense of course as it is unproven.
