[50mhz] [PNWVHFS] Update Cycle 24

[Pete]

Doc,

I have often observed brief 6m openings while centered precisely between or on the edge of severe WX fronts, and was ridiculed for suggesting a connection, only because no hard data exists. Weather (and any propagation phenomena as a result) just changed too fast for a reasonable study... until now perhaps. Computer programming and capability have improved tremendously since I discussed this last around 1987. Maybe someone will pick up the torch.

Fifteen to twenty years ago, I remember a (2 part?) article in QST about this very topic, (severe thunderstorm fronts?) but aside from anecdotal and circumstantial events, I seem to recall that the theory was left unresolved, again mostly due to insufficient data. The article entertained the possibility that shear and front patterns may be what's RESPONSIBLE for producing ionization at VHF regions to stimulate Es as we know it, and NOT that the annual Es seasons happen to fall during the times of year we get the most violent weather.

The subject may have since been revisited in a publication I haven't seen or heard about, and anyone on the list can tell me if it has; I'd like to know.

One thing for sure; even if there ever comes a time when everything about 6m propagation becomes completely understood and predictable, it will never lose its charm for me as the Magic Band.
