Making a Twister / Tornado using CC Particle World 

Create a particle twister in Adobe After Effects with no plugins.
Here's a quick tutorial showing how you can create a particle Twister in Adobe After Effects, using just the native plugins, mainly Cycore's CC Particle World with a bit of CC Vector Blur too.
I use a set of expressions from a previous tutorial, Linking CC Particle World to a 3D Null in After Effects: • Link CC Particle World...
Expressions used for the 3D NULL link:
Position X:
x=thisComp.layer("Null 1").transform.position[0]-thisComp.width/2;
x/thisComp.width;
Position Y:
y=thisComp.layer("Null 1").transform.position[1]-thisComp.height/2;
y/thisComp.width;
Position Z:
z=thisComp.layer("Null 1").transform.position[2];
z/thisComp.width;
-------------------------------------------------------------------------------
Adding a wiggle in only two directions / axis:
X = wiggle(1,50)[0];
Y=value[1];
Z=wiggle(1,50)[2];
[X,Y,Z]
