My first take on a hurricane made completely within nodes and without using a masking image, as my goal is to have it completely procedural.
I used a "simple shape" circle to flat out the center and another for the hole.
A question though, how could I easily add some roughness (uneven) edge to the simple shapes?

Add a warp shader under the simple shape, add a vector displacement shader as function input of that warp shader and use a PF as input for the vector displacement shader, which combination will push and pull the edges of the circle about. Then play with values, and see what happens. Too much and the circle will 'desintegrate', so it takes some experimentation. Or a simple fractal warp can do a lot to that simple shape shader (SSS), but is less controlable.
Some progress made, I feel more confident with the nodes thanks to your help :) Further feedback and suggestions would be much appreciated though!

Very good!

Wonderful ;)
When I started on this I did not take the scale into account, since I was just testing it out. So now it's scaled up to a more realistic size and detailing. Also moved the eye-of-the-storm and rotation a bit off center to create a "throw out" effect as the hurricane is moving. The eye is wide here... reminds me of the NASA documentary when flying into the eye and taking all kinds of measurements, that was a wild ride! At least before they reached the eye...
What do you think?
Now I want to add a kind of explosive effect with clouds spread outward from a center + mackerel clouds/ridges on the disc. Any tips on how to do that?
Cheers :)

Morning! An updated version, changed the eye to use altitude offset instead. Much better and with taper control of opening at depth. Very nice effect! Also many other subtle improvements. Next would be to add some "wind" effect on the edges.

Some adjustments

It looks very good. I guess you'll be adding some 'normal' cloudcover too?
Great to see your progress! It's definitely looking good. I'm not sure I've seen someone take the procedural approach this far (well, except for Hannes' tornado, hehe). Some of the better hurricanes of the past have been image-based masking I believe. So I'm very curious to see what the end result looks like here.

I like this a lot and having failed a few time in my attempts I now know I just gotta keep on tweaking....

Thanks, love to hear that! Yes I plan to add it into normal clouds in different scenarios. It will be used in airline flight training courses. But also for a lot of other things in my personal projects.

Appreciate that! And yes, the tweaks, the tweaks;)

Oshyan, thanks for that:) I will def check out Hannes' tornadoes. Yeah I'm curious too on the end here, really fun and such a journey to learn Terragen!
A closer look of the eye :o

I think the top of the big cloud is a bit flat. I'd add some detail there.

@Dune agree and is also what I want. Struggling a bit with the balance of tapering the height so the outer clouds don't get too high.
