Looking for the originals I contacted one of the writers. They might be lords of mathematics but they are only people too neither.
(He might say "Get lost".) …
The application of Lobe Dynamics to Baratrophic wave breaking.
The title is a fair mouthful is it not?
I couldn’t understand much of what the article e was discussing but the diagrammes were self explanatory. (I hope.)
They come at the end of the PDF on pages 22 to 26.
It looks like “vortex shedding” is an adjunct to the rotation of pressure systems.
Imagine an onion that has started to sprout.
If you cut it across the top the section will show that the inner layers have developed into two units. (You get the outer layers; so many skins of onion that wrap around the whole sphere, then inside two onions, ellipsoids. One of them the sprouting one the other waiting its turn.)
Apparently the same sort of thing develops in rotating liquids. The model depicted what appears something in the shape of a sprouting legume. Conchoidal, spiralling out around the skins, breaking through one at a time.
The figures go on to show the successful cell as resembling jet streams. The “shoot” breaking off the parent as excrescences, joining up with the outer layers.
In the model this happens in about 7 days. Which is something in the vicinity of the length of an unmoderated weather spell – a lunar phase. Keeping the model going –as would happen if there are two or more similar phases running consecutively (and little to spoil the other “parameters”) the active ellipse breaks out from the mutual centre.
OK. This all took place from day ten to seventeen or so. The figures show the whole development which isn't nearly the same – but hell the earth has been running the real thing since Adam was a lad.
It actually explains the "5 day wave phenomenon" that is seen over many continents. Actually it is occasionally seen over the North Atlantic too -in my opinion but there is so much to see at sea that it is easy to miss.
Day 1 the fluid revolves about its common centre.
Day 2 the centre becomes off-set leaving another ellipse to form in the slack.
By day 5 the active “centre” is now an ellipse displaced toward the outside.
By day 7 it is elongating to form “trough”.
And by day 10 the trough becomes a spur that curves around the spheroid.
Day 15 the spur breaks off.
Figure 1 apparently depicts the forces of the dynamics involved. It is good their model gives figures they can work on.
But more interesting, to me at least, is it gives some inclination why at low levels, there should be a Low at Iceland whilst there is an High over the Arctic.
And never the twain shall meet.
Take a look for yourselves:
There is another one here at:
This one is actually discussing a sea current. The computer I am using had siezed up so I have to close it to get a restart I think.
Damn I am going to have to get an internet connection at home. The thing is, I am going to move soon, once again so I don't want to set one up just yet.
This is annoying though!
