Cloud Streaks Using 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!

[I am using Eevee rendering engine]

Edit:

Added my shader setups for world and volumetric fog.

  • $\begingroup$ That looks like the job for some sort of noise texture set up as world shader background, not a particle system $\endgroup$ – Duarte Farrajota Ramos Apr 2 '20 at 14:31
  • $\begingroup$ Can you help me with the node setup? I have already created a simple gradient background and volumetric fog, but I have never used noise texture before. $\endgroup$ – i_am_kym_1996 Apr 2 '20 at 17:50

    $\begingroup$ It does not look like a lot of clouds, how about drawing or modeling them? $\endgroup$ – Leander Apr 2 '20 at 18:38

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.
