Fort Collins, Colorado "Kelvin-Helmholtz Waves"

In fluid dynamics, vorticity is the curl of the fluid velocity. It can also be considered as the circulation per unit area at a point in a fluid flow field. It is a vector quantity, whose direction is along the axis of the fluid's rotation. For a two-dimensional flow, the vorticity vector is perpendicular to the plane.

Experts say the clouds were pristine examples of "Kelvin-Helmholtz waves." Whether seen in the sky or in the ocean, this type of turbulence always forms when a fast-moving layer of fluid slides on top of a slower, thicker layer, dragging its surface.
Water waves, for example, form when the layer of fluid above them (i.e., the air) is moving faster than the layer of fluid below (i.e., the water). When the difference between the wind and water speed increases to a certain point, the waves "break" — their crests lurch forward — and they take on the telltale Kelvin-Helmholtz shape.
With the entire planet subjected to atmospheric manipulation, where discrete layers of the atmosphere can be altered independently of the layers above and below it, these kinds of waves have become common and can been seen at virtually ANY altitude.

  • Wow, again, very impressive research and reporting. How are we going to stop all this Scott? Are we realistic in believing that we, as common citizens, can? What fear is this causing and how should we manage that fear? Can it BE stopped, sir? What can a single woman in regular life, or an retired man on a fixed income really do about this? How much have we really changed anything "they" do? How do you advise, Scott?

  • Incredible, Thanks Scott

  • Thank you Scott. Great information.
