That's easy.  Ground waves are always vertically polarized.
Thus if the noise is from a ground based source, and starts
out with both polarizations, only the vertical polarization
survives any significant distance propagating along the ground.
This of course is why AM BCB stations are vertically polarized.

I have taken portable vertical antennas out to places away
from any power lines and they are as quiet as a churchmouse
when the band is closed.  In those areas, they work great
as receiving antennas.  Just as good as a dipole.
