MW propogation and weather

"Telamon" wrote in message ... 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. Tim. |

Somebody somewhere must've done a more global study. Not sure, it would be interesting trying to find out though. I wonder if Tomas Hood has done any studies on this? He has an excellent SW propagation page at http://prop.hfradio.org/ . It even features forums for discussion of the subject, although I have not had time to really delve into it. Jackie |
