MW propogation and weather
In article . net,
"Verstaldin" wrote: wrote in message oups.com... 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.

Our weather in the troposphere can't though. My compass is still working so the earths magnetic field is still OK. -- Telamon Ventura, California |
