You can't apply those to a particle emitter. Though you can use a particle emitter to create a tornado quite easily.

Steps:

1. Create particle emitter, the Big Bonfire is a good preset to start with
2. Change the particle shape type to sphere for a billowing tornado or rectangle for a smooth whirling tornado
3. Increase the velocity to 8 or above and make the particles free.
4. Scale the emitter in assembly.
5. Apply a spin modifier on the z axis and increase the speed of the spinning to something to you liking
6. Apply a blur effect to the emitter of 4% with gaussian selected and high quality
7. Apply a smokey looking texture 8. Also add some 4d clouds with spherical setting centered at the base with the same spin modifier applied at a slightly faster speed and another one at the stop of the emitter rotating slightly slower color the clouds a dark gray to match your tornado 9. You can also add another emitter similar to the first scale it slightly larger and use the same preset and velocity options as the first one, just decrease the particle amount and make the shape a rectangle, apply a texture map and transparency map to the emitter that will give you a somewhat random looking "debris" 10.
