Solar Activity
I was chatting with a meteorologist the other day and he was telling me that
people in the know are more worried about the lack of Solar activity than in Global Warming. It appears that long periods of low or no solar activity can result in major climatical changes such as mini-ice ages. He thinks that the lack of solar activity could heavily influance the seasons. Any discussion would be welcome. I would like to find out what other people think. Thank you, Art Martini Bruneau Dunes Astronomical Observatory Boise Astronomical Society |

Thank you, Art Martini Bruneau Dunes Astronomical Observatory Boise Astronomical Society I've spent a large portion of my working life dealing with long distance H.F. radio communication. During this time we were made aware that the level of Sun Spot activity had an effect on the ionization levels of the ionosphere, and therefore on H.F. communications. The Sun Spot cycle varies over an approx eleven (11) year cycle, minimum to maximum to minimum. Late in my working time, I became aware that there was also an approximately ninety (90) year super-cycle which applied as well. There has been some work done (by Gov weather bureau I believe) relating this 90 year cycle to droughts here in Australia. Australia was in drought just prior to WW one and again now, so time frame roughly matches. Daniel Daniel -- Posted via a free Usenet account from http://www.teranews.com |

Thank you, Art Martini Bruneau Dunes Astronomical Observatory Boise Astronomical Society Here is a general discussion: http://wattsupwiththat.wordpress.com...sunspots-gone/ The concern at the moment is not that we are at a Solar minimum, we get there every ~11 years, but that the start of the next cycle is late and showing a strange 'flatness'. There are recorded periods in history where climatic cooling appears to coordinate with lack of Sunspots. We really don't know that much about what the effect of this delay might mean. AWG - Greenhouse Gases is the predominate theory of most climatologists, and no one can come up with a plausible mechanism for how Solar Activity directly effects the planet's climate. We will just have to wait and see. -ralph |
