| I will be brief, and I may or may not be wrong about something. This should help or give an idea as to how to create them.
| Creating spiral—or hurricane—like clouds without using cubemaps requires the Axial Tilt Domain Warp. Once an Axial Tilt Domain Warp (I'll refer to it as ATDW) is added to a noise, there will be four parameters that/can be adjusted:
The first parameter, the axis, determines the position. They go in the order of X, Y, Z. At least one of the values must have a value +0; otherwise, they will not spawn.
The second parameter, the angle, determines how twisted/warped/swirly/hurricane-like it is. One ATDW will always spawn two storms. One storm will always spin clockwise, and the latter will spin counterclockwise. By inputting a negative value, you can flip the orientation (e.g., a storm that spun clockwise now spins counterclockwise due to the negative value flipping the orientation). The higher the value, the more swirly it is (the same goes for the negative value).
The third parameter, the exponent, determines its size. The lower the value, the larger the storm/swirl, and vice versa for the higher values. DO NOT enter a negative value like the angle, otherwise you break the noise.
The last parameter is the method. There are only two methods that allow for swirling: Distance From Axis (DFA) and Distance From Axis Inverse (DFAI). For creating storms and hurricanes, DFAI is your best bet, as it is a lot more customizable and can be sized. On the other hand, DFA is more for storms on tidally locked planets or planets with just two large storm systems. Unlike DFAI, they cannot be sized, as their size is always constant. The axis controls the position and the angle, and the exponent controls the swirliness.
