How to create stylized cloud streaks like these using a particle system? I have attached a sample picture from Matkovski Dragos' project "Illustrat3d Nature". I looked up for the workflow to create clouds like these, but I didn't have any luck with that. The only thing Dragos mentions about the clouds is that they are created using a particle system to create infinite variation.

I am assuming we use emitter particle system to create these, but I am relatively new to this topic so I could be wrong.

Any help is greatly appreciated. Thanks!

Edit:

Added my shader setups for world and volumetric fog.
Maybe you can use some sort of Musgrave or Voronoi texture to form the base clouds, then mix up texture coordinates with a Noise texture to distort them into something more irregular.

Squash the textures in Z, or stretch in XY to get the elongated look.
