No, it's less attenuation in its normal mode of propagation. It has to do
with the decompression of the magnetosphere on the side of the earth away
from the sun..

Almost all AM radio stations transmit in the vertical polarization, the
antenna beam launch angle is low, it's difficult to get skip.

Horizontal polarized antennas (spaced properly above a ground plane) have a
launch angle that is favorable for skip.

If it was skip, there would be regions of no reception between regions of
reception. AM radio is continuous reception until it just fades out.

You can get AM wavelengths to skip, but it is not as common as in other
shorter wavelengths.

this crap:

AM (600-1600 KHz) is a ground wave. It doesn't skip.

It travels further at night because the ionic concentrations in the
Appleton
layer decrease from lack of sunlight and the solar wind.

Well gee, that's a skip, isn't it?
