Do weather changes affect the ionosphere in the lower layers that are
responsible for night time propagation?

I've wondered the same thing. If we're technically at "solar minimum" in
terms of solar activity, and yet our reports show something of a change in
reception/propagation, I have to wonder how much geophysical events effect
MW propagation.

Well, there are obvious winter/summer and day/night effects. In fact
the warm front preceding the storm system produced temperatures in the
mid-80's here, in what is still technically winter! Does that mean that
my expectations of "summer" vs "winter" MW propogation should change
when the temperature goes up and down?

And I've wondered if solar activity/storms etc. affects weather and
storm patterns on earth. I have some anecdotal experience (gees, that
was a big solar event, and hey we had bad thunderstorms last night
too!) but I don't believe just that. Somebody somewhere must've done a
more global study.
