POP Curl noise only on X and Y plane?

[terencemace 3]

Hi all, I've had results making curl noise particles, I am now trying to "lock" the curl noise ONLY on the X and Y plane. So the particles, trails, are only flowing on a plane. Starting in the center, or emitting from a circle curve. That's the critical part. I see how flow lines are created, but I need the particles to do the work. *Ultimately I need to create really round particle swirls.

Any ideas?

Thanks! T

Hey, actually like this. But starting from a central circle shape.

Thanks for any insight.
