Propagation... why do I miss some signals?

We are not receiving detecting RF like in a radio wave.

I'm not a physicist, nor do I have any doctorate degrees. I do know some (on ham.stackexchange.com) whom I could ask, but I'd rather not get into this now. I fear that it might just cause hard feelings. :-)

Information 
For some time --and especially in the past few days-- I have noticed that stations on either side of the US-Canada border sometimes pick up many more strokes in South America and far out into the Atlantic Ocean than more southern stations. This is after dark.

There's more to it than described above, but it seemed to me that propagation was also distinctly favoring N-S paths over E-W paths. Anyone else ever notice this?

The documents below confirm that that happens.

Here's a screenshot of one page of the first pdf.
   

There much more extremely interesting information concerning ELF/VLF propagation there.
