VORTICITY, a beautiful fluid mechanics phenomena, but which can have devastating effects on human settlements, when of very large scale and very powerful.

The complete vortex has a “donut” shape. Fluid/wind sweeps in along a flat bottom (ground level, or sea level), increasingly curving as it converges to the central “funnel.” There, it spirals up and as it rises it also spirals outward, and the curvature of the “path lines” diminishes at further radial distances. “Out there” those pathlines (water flow, winds) cycle back down to the “bottom” plane, completing a circuit, and then flow in again.

Versions of vortices are everywhere: bathtub drains, river eddies, hurricanes, water spouts, airplane wingtip vorticies, Great Red Spot on Jupiter.

Herman Helmholtz (19th century physicist) published his conservation law of vorticity (Helmholtz Vortex Theorem), and the differential equation form of vorticity involves “the curl” (a differential vector cross product of the velocity field). Vorticity features in Boundary Layer Theory (for the thin viscous layers adhering to material bodies moving through fluid bodies, like airplane wings, and further explicated by Von Karman, in the early 20th century, about the trailing Von Karman Vortex Street behind airplane wings, a consequence of fluid viscosity).

The best (and still and forever likely to remain incomplete) theory/description of fluid turbulence is that it is a nested set of vorticies of increasing scale, from the nearly molecular up to larger and larger eddies until a macro-level of fluid mass circulation — like a tornado.

If the fluid is electrified, and consequently magnetized, like the atmospheres of the Sun and stars, Earth’s ionosphere and the Earth molten core, and so much of Space (nebulas, planetary rings, space plasmas: novas and supernovas and rarefied space dust), then electric and magnetic vortices can form: Earth’s magnetic field is one example of the outer “path lines” of Earth’s ‘magnetic tornado’ at its core.

Vorticity in its many forms is quite fascinating, but of course violent vortical weather like hurricanes and tornadoes can be so harmful to living creatures: plants and animals, including humans. The American Great Plains are a natural “Tornado Alley” because of the expanse of flatness allowing the geometry of the tornado vortex free reign to expand without restraint. Also, they form there because warm humid air from the Gulf of Mexico is propelled northward (by its contained heat energy = “high pressure”) and over the Plains it collides with strong colder winds sweeping down eastward from the Rocky Mountains (the Front Range), and that collision of low hot moist northward wind with high dry cold eastward winds creates a counterclockwise circulatory motion of atmospheric masses, with moisture rising (in the central “funnel”), chilling, raining out, freezing into ice crystals and hail, and the friction of that creating electrical charge separation (“static” electricity) which sparks over as lightning.

The point about Helmholtz’s Vortex Theorem is that the continuous threading of the “path lines” into the vortex “spool” makes of the whole an integral energetic structure, and that integrity is maintained — conserved — despite forces imposed on the whole of it: which is why hurricanes and tornadoes move, intact, across the face of the Earth because of the imposition of pressure gradients from “high pressure” regions to “low pressure” regions.

Another aspect of Helmholtz’s theorem is that, like a spinning ice skater, the slow gradual circulation out at vast distance (ice skater with arms extended, spinning slowly) represents an angular moment that is maintained close to the center by a very rapid rate of spin (ice skater with arms pulled in, spinning quickly).

So it takes quite a bit to dissipate the vortex, in fluids it is the result of the build-up of friction (fluid viscosity) gradually breaking up vortical motion into randomized turbulence (in the absence of strong external — collisional wind — forces causing a macro “stirring” into counterclockwise circulation — in the Northern Hemisphere). Stirring cream in your coffee is a nice way to observe vortical motion and vortical mixing.

Back in the 1980s I had a lot of fun working out a theory of electromagnetic vortices (all based on the work of famous physicists, like Debye, Alfvén, Cowling, and their MHD and plasma physics predecessors), which I found were produced by nuclear explosions in magnetized spaces, and in very high current and high power electrical transmission lines as used for fusion power and particle beam research.

If you have a poetic inclination toward reading about vortices, look into the book ‘Sensitive Chaos’ by Theodor Schwenk, an anthroposophist — influenced by Rudolf Steiner — about the many intriguing patterns in fluid flows of all kinds (as in our blood streams, the swirled forms of some of our blood vessel junctions and valves).

Nature is endlessly fascinating and instructive.



Hurricane Florence, 9-11 Climate Change Terrorism


Hurricane Florence, 9-11 Climate Change Terrorism

NEW 9-11 TERRORIST ATTACK!! Yes, it’s true! Today (11 September 2018), terrorists based in Washington D.C., and sponsored by the dinosaur bones mining, pumping and burning industries, have relaxed rules restricting methane emissions from mines and oil and gas wells (for privatized profits at socialized costs), which will result in enhanced hydrocarbon atmospheric pollution that will accelerate Global Warming.

AND JUST IN TIME! Because Hurricane Florence, currently a Category 4 hurricane (and possibly strengthening toward the maximum possible, Category 5) is barreling down on North Carolina (a good choice, they voted for Trump), and 1.5 MILLION people have been urged/ordered to evacuate from coastal areas.

Hurricane Florence is being amplified by Climate Change (Global Warming) because:

1) the sea level is now higher (by about 1 foot in the western Atlantic near the Carolinas) because of previous ice cap melting and runoff (and heat-induced expansion of seawater), so the “storm surge” (like an extra super duper high tide) flooding of coastal lowlands, swept in by the hurricane, will be more extensive (i.e. worse); and

2) because the ocean is warmer (by Global Warming) and thus has much more energy (heat) available to pump up wind speed/energy in hurricanes, and so they have more capacity to destroy structures and infrastructure (like telephone and power poles, and fallen power lines start fires; also to uproot trees, smash houses and lift off roofs); and

3) because Global Warming/Climate Change has altered the path of the Jet Stream —

the high-latitude, high-speed, high-altitude, west-to-east ring of wind current that normally pushes Atlantic hurricanes eastward back out into the Atlantic Ocean, away from the US East Coast —

(has altered the path of the Jet Stream) farther to the north, so it now DOES NOT push Atlantic hurricanes toward the east, away from the US East Coast. So Hurricane Florence will stall when it makes landfall, and dump humongous amounts of rain in the same spot (same localized region) of mainly North Carolina, which will cause huge inland flooding. This is exactly what happened last year (2017) with Hurricane Harvey over Houston, which resulted in the largest flooding event in US history.

We can expect fatalities of American citizens.


– all these coming effects of Hurricane Florence (and Hurricanes Helene and Isaac, right behind) were known to be inevitable, and

– since Global Warming/Climate Change is known to be the “natural” culprit (super-charging an already dangerous natural weather event), and

– since pollution by greenhouse gases is known (and has been known for over half a century) to be the human action producing the super-charged “natural culprit” of this approaching Climate-Weather Catastrophe, and

– since it is known that this human action has been committed by high U.S. government officials solely for the pecuniary advantage of the fossil fuels industries (who fund these pols’s kick-backs), and

– as it is known such action will directly harm — even kill — American citizens,

– then it is directly clear that said high U.S. government officials are committing premeditated murder (and at the very very minimum reckless endangerment including manslaughter).

This is all-out terrorism against millions of Americans on US soil.

The US War On Terror needs to focus all its forces on Washington D.C., and Wall Street, New York City (and its satellite corporate terrorist base camps, cash dumps and training centers lurking deep in the Uncle Sam Homeland), and capture and liberate that currently occupied — by neo-fascists — national capital city.

At this moment, murder charges could be filed in any state court against these still-at-large-criminals (hiding out in bought-elected federal and state offices) because of the direct linkage between their premeditated actions, their criminal intent to harm rather than protect American citizens (a direct violation of their oaths for government service, and their primary duty as members of American government: protecting the public) and the past and now impending and inevitable harm to be suffered by many members of the American public.

9-11 terror is here now, but on a continental scale, not just a citywide scale — with Hurricane Armageddon on the East Coast and Gulf Coast, Wildfire Armageddon west of the Great Plains, and more and bigger tornadoes inevitable for the Mississippi Watershed and Great Plains.

We are having our continent-wide mainland USA “Pearl Harbor” attack by Climate Change-amplified weather, which is state-sponsored terrorism that is caused directly by the fossil fuel industry-owned terrorist-capitalist network of Republican Party and corporatist Democratic Party pretenders and occupiers of U.S. Government (and states’ governments) Executive, Congressional and Judicial public offices.

This is treason, and demands a complete and thorough revolution.

This is how the world ends: will we soon see category 6 hurricanes?
