Satellite Clouds

As a part of my cloud system i tried to simulate satellite clouds ,which is not that bad....but still need to implement the vortex stuff  none but the cyclone clouds ...a common stuff in weather report...

Initially i displaced the volume with  a turbulent noise through a transformation matrix and used a curl noise to drive the rotate parameter of the transformation matrix.finally another turbulent noise is used to drive the offset of the first turbulent noise.Length of the position is taken and multiplied with user parameter (displacement) which will drive the amplitude of the curl noise.
