I wonder what influence the terrestrial field exerts on the incidence of particle bombardment resulting in cloud formation. Obviously it doesn't matter diddly with the high energy critters (cosmic rays). However, given that small distinctions from such a singular and powerful source could make significant perturbations on earth, one wonders.

Don't be too sure that it "doesn't matter diddly". The solar magnetic field (whose strength varies, and which sunspot numbers are correlated with) is vast, and has a BIG effect on how much cosmic ray energy hits Earth

I was talking about the earth's magnetic field, not the sun's.
