Hurricane type effects

[art3mis 27]

Could any Houdini experts suggest how to approach 'swirling clouds' aka hurricane type effects?

Trying to create something similar to the following, but on a 'smaller scale' ie greatly sped up. So  if you could imagine a whirlpool effect but with clouds instead of water.

You can make a simple twist deformer, rotate around origin and vary the twist by distance from the origin. Then animate the twist and the spin, calculate the velocity with a trail sop, use it as a source for a volume.
