[Researchers] have a new model for explaining how clouds move and change shape in brown dwarfs, using insights from NASA's Spitzer Space Telescope. Giant waves cause large-scale movement of particles in brown dwarfs' atmospheres, changing the thickness of the silicate clouds, researchers report in the journal Science. The study also suggests these clouds are organized in bands confined to different latitudes, traveling with different speeds in different bands.
"This is the first time we have seen atmospheric bands and waves in brown dwarfs," said lead author Daniel Apai, associate professor of astronomy and planetary sciences at the University of Arizona in Tucson.
[...] "The atmospheric winds of brown dwarfs seem to be more like Jupiter's familiar regular pattern of belts and zones than the chaotic atmospheric boiling seen on the Sun and many other stars," said study co-author Mark Marley at NASA's Ames Research Center in California's Silicon Valley.

And giant electrical arcs pass through the dusty clouds fusing clumps of it together. These concentrated points become shorter paths of least resistance and accumulate more rock as they're tossed about in the violent winds, much as hail ice does -- starting as single molecules and sometimes winding up the size of softballs here in Earth's thin atmosphere.
Then ancient sky-watchers document the birth of new planets "vomited" from the mouth of a God, parts of those planetary gods even falling to earth and impregnating the world in their legends. No, of course not, it couldn't be that our accretion disk theory of how planets, moons and asteroids form is totally bogus and unable to explain the amount of cratering -- cratering that is almost always 90 degrees perpendicular to the surface, like all electrical bolts are but most "collisions" would not be. No, of course the ancient legends are pure poppycock, and not based on a morsel of truth at all.
TL;DR: Dude, they're bullshitting you. They don't know fuck-all about weather unless they've modeled electromagnetism, and they haven't.

What if I told you, what you claim is utter bullshit?
Where's your actual calculation, based on an actual model rather than fuzzy prose, that agrees with the observation and doesn't contradict any of the millions of experiments done down on earth (and in near-earth space)? Note that not a single experiment done on earth contradicts in any way the established theories of physics on which those models are built. That experimental data is much better evidence than a liberal interpretation of ancient myths.
