Sure, there is:

• -Keying it
• -Curve Flow
• -Path Flow

But in your case, as stated above by satch, your best and easiest bet at this point would be to:

• -Make your mountaintop geom LIVE.
• -Draw a curve on it (or duplicate one)
• -Make that curve an emitter.
• -tweak the particles emitting from it so they emit from the areas of the curve to your liking. (paint weights, or whatever)
• -also tweak the emittrer to emit the particles in the Y direction.
• -attach an AIR field using the WIND setting.
• -attach gravity to the particles. (just a teeny bit)
• -make the particles and mountain object "collide" just for safety
• -make the particles dissipate/fade the closer they get to the moutain geometry via sdk, OR the SPREAD attribute of either the WIND and/or the emitter itself, OR just make them fade after a few seconds. (easier)
• -Attach turbulence AND vortex field(s) to the particles and tweak the vortex field to get the particles to "swirl" a bit, and tweak the turbulence to get the particles to randomize thier look a bit

good luck!
