Default Motion of Charged Particle in Magnetic Field

Could someone here please tell me if there is any scientific relationship
between "motion of a charged particle in a uniform magnetic field (earth's)" and
the dynamics of a hurricane and a tornado? I am not speaking of the Coriolis
effect.

See:

Thank you for your help
Bill

The page is true enough, but all it does is describe the Lorentz force.

In order to apply to the atmosphere at any significant degree, a
significant part of the atmosphere would have to be charged. It isn't.
The Lorentz force is an important consideration only in the ionosphere,
over 100 km up. For the troposphere, the lowest 10 km, including where
we are, it's negligable.

Hmm. Interesting thing. The magnetic field points in the same
direction (South Magnetic pole to North Magnetic pole) everywhere.
B is, then, aiming in pretty much the same direction whether you're
at 45 North or 45 South. Given that, if the magnetic field _were_
important, then storms should rotate in the same direction for
both hemispheres. While toilets and kitchen sinks don't reliably
show the effect, storms do, and it's to rotate in opposite directions
in the two hemispheres.

Bill Orr says:

Thank you, Robert. You provided the information I wanted. There are still many
unknown questions
concerning hurricanes and tornadoes. and cloud electrification. Science still
has a ways to go but they will get there for isn't that what science is all
about.

Cheers
Bill
