Donk Posted August 26, 2009 Report Share Posted August 26, 2009 The Pacific El Niño, triggered by sunspot minima...Sorry, I don't see it.wiki: El Niño/Southern OscillationMajor ENSO events were recorded in the years 1790-93, 1828, 1876-78, 1891, 1925-26, 1972-73, 1982-83, and 1997-98. Recent El Niños have occurred in 1986-1987, 1991-1992, 1993, 1994, 1997-1998, 2002-2003, 2004-2005 and 2006-2007.Solar minima 1784, 1798, 1823, 1833, 1843, 1855, 1867, 1878, 1890, 1902, 1913, 1923, 1933, 1944, 1954, 1964, 1976, 1986, 1996, 2008. I've emboldened the (very few) dates which appear on both lists. I've even given you 1890, as it's close to 1891. Can you point me to somewhere that proves the correlation you're asserting?

Turtle Posted September 4, 2009 Report Share Posted September 4, 2009 possible effects of no sunspots aside, the observable phenomena we currently have makes for unique opportunities. :eek: boldenation mine in the following quote. :eek2: :shrug: ;) NASA - Are Sunspots Disappearing?..."According to our measurements, sunspots seem to form only if the magnetic field is stronger than about 1500 gauss," says Livingston. "If the current trend continues, we'll hit that threshold in the near future, and solar magnetic fields would become too weak to form sunspots." "This work has caused a sensation in the field of solar physics," comments NASA sunspot expert David Hathaway, who is not directly involved in the research. "It's controversial stuff." The controversy is not about the data. "We know Livingston and Penn are excellent observers," says Hathaway. "The trend that they have discovered appears to be real." The part colleagues have trouble believing is the extrapolation. Hathaway notes that most of their data were taken after the maximum of Solar Cycle 23 (2000-2002) when sunspot activity naturally began to decline. "The drop in magnetic fields could be a normal aspect of the solar cycle and not a sign that sunspots are permanently vanishing." ...If sunspots do go away, it wouldn't be the first time. In the 17th century, the sun plunged into a 70-year period of spotlessness known as the Maunder Minimum that still baffles scientists. The sunspot drought began in 1645 and lasted until 1715; during that time, some of the best astronomers in history (e.g., Cassini) monitored the sun and failed to count more than a few dozen sunspots per year, compared to the usual thousands. "Whether [the current downturn] is an omen of long-term sunspot decline, analogous to the Maunder Minimum, remains to be seen," Livingston and Penn caution in a recent issue of EOS. "Other indications of solar activity suggest that sunspots must return in earnest within the next year." Whatever happens, notes Hathaway, "the sun is behaving in an interesting way and I believe we're about to learn something new." Quote Link to comment Share on other sites More sharing options...
Turtle Posted September 5, 2009 Report Share Posted September 5, 2009 possible effects of no sunspots to the fore, the observable phenomena we currently have makes for interesting speculation. B) the full article at the link has some graphs of the pertinent data sets. :eek2: SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroidsSeptember 5, 2009 SOLAR MINIMUM VS. GLOBAL WARMING: From 2002 to 2008, decreasing solar irradiance has countered much anthropogenic warming of Earth's surface. That's the conclusion of researchers Judith Lean (NRL) and David Rind (NASA/GISS), who have just published a new analysis of global temperatures in the Geophysical Research Letters. Lean and Rind considered four drivers of climate change: solar activity, volcanic eruptions, ENSO (El Nino), and the accumulation of greenhouse gases. ...Volcanic aerosols are a source of cooling; ENSO and greenhouse gases cause heating; the solar cycle can go either way. When added together, these factors can account for 76% of the variance in Earth's surface temperature over the past ~30 years, according to the analysis of Lean and Rind. Several aspects of their model attract attention: "The warmest year on record, 1998, coincides with the 'super-El Nino' of 1997-98," points out Lean. "The ESNO is capable of producing significant spikes in the temperature record." Solar minimum has the opposite effect: "A 0.1% decrease in the sun's irradiance has counteracted some of the warming action of greenhouse gases from 2002 - 2008," she notes. "This is the reason for the well-known 'flat' temperature trend of recent years." ... Quote Link to comment Share on other sites More sharing options...

When sunspots are plentiful, the aurora become more visible from populated regions on the earth. There are always aurora in rings around the north and south magnetic poles. Only during periods of high auroral activity do people in the warmer land areas well away from the poles begin to see them. Then the Northern Lights are visible to much of the northern United States and Europe. ... we'll get to the rest in good time; perhaps when i'm better fed and sporting a sunnier disposition. :hihi: Quote Link to comment Share on other sites More sharing options...

That pun was spot on. :hihi: thnx dude. just another aspect of my magnetic personality. ;) we now return you to our regularly scheduled broadcast. NASA - Deep Solar Minimum...In a way, the calm is exciting, says Pesnell. "For the first time in history, we're getting to see what a deep solar minimum is really like." A fleet of spacecraft including the Solar and Heliospheric Observatory (SOHO), the twin STEREO probes, the five THEMIS probes, Hinode, ACE, Wind, TRACE, AIM, TIMED, Geotail and others are studying the sun and its effects on Earth 24/7 using technology that didn't exist 100 years ago. Their measurements of solar wind, cosmic rays, irradiance and magnetic fields show that solar minimum is much more interesting and profound than anyone expected. ...

Green Revolution stalls, a billion people starve. Enviro-whiners deny a solar minimum cooling trend is upon us. In theory Mauna Loa is sampling the "well-mixed" lower stratosphere dozens of times/day, and with great care to get honest numbers. In practice, there would be boxes aboard commercial long haul airlines to get spatial as well as temporal data across huge swaths of the planet at ~30,000 feet. Mauna Loa is 11,000 feet.

abx-sun Posted December 11, 2009 Report Share Posted December 11, 2009 Since two years, the solar spots are no longer following the predictions.The so called "experts" at NOAA Space Weather Prediction Center predicted in January 07 the beginning of the cycle 24 to occur in mid 2008. As this did not occur, they shifted theprediction one year later to mid 2009.Now we are at the end of 2009 and still no beginning ofthe next sunspot cycle ...Furthermore, they reduced the predicted maximum from 140 to 90 sunspots, and delayed the predicted peak also one year.Now have a look at the latest update of the preditions(2009 Dec. 8), and you see that still the preditions areway out of reality ... see: sunspot-08-09.htmlThere you also see the previous predictions that wererevised and revised ...I ask, why the "experts" still continue to make new predictions, as the situation is so undecided, that we mayeven enter a "maunder minimum" or any kind of solarspot maximum between 25 and 150 ...Would it not be wiser if the "experts" would say: We cannotmake any valid prediction, as the present behaving of the sunis completely out of the our knowledge ?

Felix HB9ABX hi felix. :hihi: the continuing changes have much to do with the new data from previously un-had sensing equipment. for example: >> ESA Science & Technology: SOHO confirms 36 year old solar theory in fact the experts often do say they don't know. a review of this thread evidences that. as it happens, today we have a new small cycle 24 sunspot. :) (Never look directly at Sol! ) Daily Sun: 11 Dec. 09Sunspot 1034 is a member of new Solar Cycle 24.

abx-sun Posted December 11, 2009 Report Share Posted December 11, 2009 Hi Turtle, thanks for your comment.Yes, I have seen the small sunspot of today, even I have seen it yesterday.And now, they call this "beginning of cycle 24" ...this happend now several times in the last 12 months!!!Each new spot was called "the beginning" - and then followed again a period of ZERO ... I bet, now it will be the same :) kind regards Felix Quote Link to comment Share on other sites More sharing options...
