MW propogation and weather
 

I'v commented before that it could take a long time to diminish altogether
s, but instrumentation exists that can measure the change.

Last night on the AM broadcast band, the stations up and down the
East Coast that traditionally boom in were not so strong.

The Canadian station on 740 which is usually all there is had some
obvious competition from stations in the SW... Texas/Oklahoma? Also
the stations from upstate New York which normally boom in had other
signals fading in and out against them.

And WGN which is not all that reliably received here in Washington
DC was booming in real strong.

Is this possibly related to the strong weather that has been moving
through the midwest (and is due to hit here on the E Coast
tonight)? Or is it just a sign of the end of Winter MW propogation?

It's possible that the presence of strong ionization in the
atmosphere caused by violent winds could steer or even absorb or wipe
out signals. Also, the earth's magnetic field is becoming weaker and
erratic. The field is going to affect how signals propogate, and if
the field changes because of the solar wind, that will also affect
it.

The lower ionosphere goes as low as 50 km to the top of the
stratosphere where it's possible the jet stream could affect it. Our
weather in the troposphere can't though.

My compass is still working so the earths magnetic field is still OK.

I rather doubt it as the D layer (lowest of the ionosphere) begins about 30
miles up.

But there's been some recent discoveries that strong lighting strikes
have an upwards effect that goes about that high. (Buzzword: Sprites.)
And, I gather, there was a whole lot of lightning in that storm.

I was just joking. Yes the magnetic pole is drifting and lately the
field strength is weakening over time.

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.

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.

Apparently there is a connection between thunderheads and the
ionosphere. There are the "Sprites" and other types of flashes seen from
the tops of storm cloud formations.
