Amazing instant stormy skies ready to animate, although I would have preferred a few more storm textures, in PNG format, I can find them, cause the model and existing jpg storm texture map is 'good enough' for openers, but if you want super high quality, all you need is to find additional environment textures or HDR or EXR of whatever works for the sphere - then turn in in the Blender Timeline 'Z' at one end at zero and the other at 360 and POOF! You have a terrific storm y sky, or any sky, depending what you put inside the sphere.
