http://www.lightningstorm.com/tux/jsp/gpg/lex1/mapdisplay_free.jsp I have found it to be a good predictor of QRN condx on 160 and 80m.

It was a great tool in my view and was introduced to me by W1IA Brent.

That might come in handy when chasing E-openings on 6 in the summer. Title: LightningStorm.com Post by: k4kyv on March 08, 2005, 07:43:05 PM I think LightningStorm.com is the best one, but here are some more free lightning map websites. Some of these are not real-time maps but indicate where the most lightning prone regions are located.

That might come in handy when chasing E-openings on 6 in the summer. I don't recall seeing any direct connection between lightning and E-openings. As cold and warm fronts bounce into each other, tropo, or tropo ducting, is common on signals above 100 MHz along the cold/warm boundary.

Pete, I was taught that the resulting wind shear from thunderstorms above a certain height , ionize patches of the E-layer ,causing openings called sporadic -E . I have noticed some tropo on 6 , but it's much more prevalent on 2 meters and above. On the other hand the MUF for E-openings rarely makes it to two meters and above. |
