Salisbury "Whirlwind"

What power can make a whirlwind form? What creates charge seperation in a cloud of dust? According to electrial theorists, it doesn't happen, in clouds, nor dust.

Salisbury just got struck with a 'whirlwind' of some power. Powerful enough to throw Ms. Scott's trailer over her house.

Her son looked out the window to find the trailer in a heap, and yet a trampoline only a few metres away was unscathed.
The sky was still clear, and the winds calm again, as if nothing ever happened.

There were come interesting inconsistencies that seems to indicate wind is not the only factor:

"The wife says the wind was blowing north and then the trailer was blowing through the air the other way."
Herb Thoms, a meteorologist with Environment Canada, believes the phenomenon was a whirlwind -- albeit an unusually powerful one.
"It is very rare they would get big enough to do what this one did," Mr. Thoms said.
However, the situation perfectly fits the profile of a whirlwind that develops very quickly and then disappears just as fast -- sometimes in seconds.

This mystery can be dealt with. There is surprising energy deficit in the idea that movement of wind can generate charge seperation to the level that it can lift structures off the ground. With a tornado there is an acceptance that the wind is more sufficent at lifting objects off the ground. But can a whirlwind?

From Thunderbolts.info:

The mechanical explanation ignores many of the conditions from which whirlwinds arise. In fair weather, with no clouds in the sky, an electric field can be measured. It amounts to about 100 volts per meter. This field is coupled to a complex of “double layers” (plasma cells), currents, and circuits that reach through the atmosphere into the magnetosphere and even into interplanetary space. Water molecules, comprising up to 4 percent of the atmosphere, have the two hydrogen atoms toward one side of each molecule and the oxygen atom toward the other. This makes each molecule a tiny electrical dipole—a pair of oppositely charged poles—subject to electrical forces. Such polar molecules will tend to line up and stick together. In a cloud they will form a leaky dielectric, storing charge and responding to the vertical atmospheric electric field.

We have been finding that on Mars, the dustdevils are obviously electrical, as the air is too thin to lift the dust off the ground.

I would bet this is 'slow electric discharge' as opposed to lighting which is 'sudden electrical discharge'.
