What i did, was made a particle effect, and changed its emmission, added a blue and white texture to it. then you make it really wide, and make the particles ginourmous(however you spell that) and then attach this script:

 var xSpeed : float = 1;

var ySpeed : float = 1; var zSpeed : float = 1;

var manual : boolean = false;

function Update () {

 if( !manual )
 {
 
     transform.RotateAround( transform.position, Vector3.right, ySpeed * Time.deltaTime );
     transform.RotateAround( transform.position, Vector3.up, xSpeed * Time.deltaTime );
     transform.RotateAround( transform.position, Vector3.forward, zSpeed * Time.deltaTime );
     
 }
 else
 {
     
     if( Input.GetAxis("Horizontal") != 0 )
     {
         
         transform.RotateAround( transform.position, Vector3.up, Input.GetAxis("Horizontal")*xSpeed * Time.deltaTime );
         
     }
     
     if( Input.GetAxis("Vertical") != 0 )
     {
         
         transform.RotateAround( transform.position, Vector3.right, Input.GetAxis("Vertical")*ySpeed * Time.deltaTime );
         
     }
     
 }
 

}

then u change the variables in the inspector on the code so that y and z are 0, and x is some random big number... then i added a new game object that was the diameter of the whirlwind. i added some cloud like particle effects to it and made them children of the new game object. i added the rotating script to that also to make it more realistic and creepyish. it looks really cool if you add white and black clouds.... and stretch them so lk the ellipsoid is x big, y and z small... or z big, and x and y small. that makes the clouds seem wispyish....

and if you want that orangish light at the bottom, i think you could probably add a sphere game object, flatten it, put it at the center, add an orangish point light.... after that, if you really want to, you can add some orange particles, and add a light emmission component, i think and make the light color orange....

is that working out for you? sometimes if you want spray, like ocean spray, you can add a mesh particle emitter component to the whirlpool object.... and make the normals negative, set its size to the same as the whirlpool
