![]() "Jim Smith" wrote in message .. . I've seen the summer of 1954 described as "the year without a summer" in the past. Just how bad was it? As bad as, say, 1985 or 1986? Or even worse than that? Any articles/anecdotal bits and pieces floating around? Jim The temperature at Kew reached 80f on only 2 days in1954 - 27 May and 1 September. I had tickets for the first 3 days of the Lord's Test Match in June 1954 ( the first ever Test match between England and Pakistan) and saw no cricket at all because of the rain.I believe it was the first occasion that the first 3 days of a Lord's Test had been rained off. The only action Isaw was players such as Len Hutton, Denis Compton and Alec Bedser strolling out to look at the wicket carrying umbrellas! One newspaper described Lord's as looking like a beach with the tide out!. Peter Clarke Ewell Epsom |

What 20-year cycle can you see then, Michael? I can't see anything of that kind, the only tendency I see is a lack of years with less than 60 hot days in the last decade and a half. It is only very roughly 20 years. Overlay http://www.climate-uk.com/EWSI.htm on the above link. By the way bear in mind interference patterns where cycles overlap. Like the nodes in accoustics. With the ideal conditions two opposite nodes will sometimes cancel each other out, sometimes work to increase the wave height or trough depth. (Which explains the missing snow for around 2001.) There does seem to be a solar max min cycle As in sunspots? I'm familiar with the theories that they affect the weather, I thought the sunspot cycle was 11 years? linked to the period of lunar nodes. (Lunar nodes are periods when the combination of the 5 degree difference of the lunar orbit combines with the eccliptic to produce declinations of 23 1/2 degrees plus or minus 5 degrees.* So are you saying that the declination of the moon (which I know can be more than 23 1/2, up to about 29 north and south), combines with the sunspot cycle to produce hot/cold weather? If so, how? (And what type of weather do various alignments produce?) Edmund |

I believe there is what is called the double sunspot cycle - related to a reversal of the sun's magnetic poles - of about 22-23 years. When some climate data are analysed that can be quite a strong signal. linked to the period of lunar nodes.

The lunar nodal cycle has a length of 18.6 years and such a cycle length (real or otherwise) has been detected in some climate data.

Yes, I think you are very much along the correct lines. It is a measure of the movement of the apparent angle of the moon above and below the earth's equator during its monthly orbit. So it is linked with the angle between the earth's orbital path and that of the moon (relative to the earth). That angle increases for about 9 years and then decreases again It reached a low point back in March 1997 and will reach a peak in March, next year.

First of all, these things can only be seen on records from one location
(any location) for the same reason that the tides will be different if they were only measured at the same time of day from the same location. Measured from every location and an average taken, a man working blindly with a thorough working knowledge of the natural history of Inner Mongolia might come to the conclusion that "tidal range" and "mean sea level" are one and the same thing. Secondly, the same celestial observations will produce different results to the OPs even if just over the hill. But you'd get to see similar cycles for vaguely similar weather regions. (You'd see it in weather stations all over Britain for example but not in the Sahara perhaps. Although I imagine runs of droughts lasting many years as in parts of Africa..... but I am guessing.) Now this is the important bit: There is a transduction of the force or enegy potential from "gravity" or/and "inertia" into something that can be translated gently into seismic waves or cloudscapes. I believe it is accoustics and I have an idea it is the effect of inertia on mascons. Possibly the rate of change of acceleration on them. I hope no one ever institutes quotations from me ad hoc (as if I were some sort of genius) that that is exactly what causes it -just because some research work yet to be done one day proves me right. I am sure it is much more complex than that. As soon as I opened those links I could see the cycles but as soon as I looked closer I could see that I could see them but that I couldn't say why. You know instinctively when something is "fitting" or "right" the way you can sense an atmosphere change when something is wrong. I'm not talking about weather here but in all walks of life. Like you can tell a great painting from a mediocre one even if they are both far better than anything you might accomplish. Sorry for waffling. It's been a long time since anyone has so much as considered anything I've said, that I just couldn't stop. -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |

Not surprising and proves the times are 'a c-c-changing'!
Imagine you used somewhere in Kent instead of Luton...... The figures would be more exacerbated from 1993 onwards. Bring on the Fans!!! ----------------------------------------------------------- "Philip Eden" philipATweatherHYPHENukDOTcom wrote in message ... http://www.climate-uk.com/Hotdays.htm Warning: you might need sunglasses gr What surprises me is how very exceptional the '60s and early-'70s were, coinciding with the period when my perceptions of the British climate were becoming hardwired. It may (though probably doesn't) explain my antipathy towards hot weather now. Philip Eden |

When some climate data are analysed that can be quite a strong signal. Quite right but bear in mind there are massive vagaries in the chronology of the solar cycle. And the only thing we know for sure about it is; there is no real direct change in the level of insolation whatever the part of the solar cycle the year is in. So are you saying that the declination of the moon (which I know can be more than 23 1/2, up to about 29 north and south), combines with the sunspot cycle to produce hot/cold weather? If so, how? (And what type of weather do various alignments produce?) If I knew that I would be an honorary professor with essays in encyclopeadias. And sunning myself in exotic locations in the company of extra-ordinarily beautiful women, of dubious reputation. The lunar nodal cycle has a length of 18.6 years and such a cycle length (real or otherwise) has been detected in some climate data. I don't think the causal mechanism has been worked out though. There won't be either. I believe that under ideal conditions this cycle can produce 3 observed solar ecclipses at any one location over some 180 years. The reason being that although the celestial dispositions take place as you say, the longitudes of the earth over which they take place are different each time. As I have posted many, many times here and elsewhere it is the longitudal positions that are the key to the whole thing. Everything else at the moment is mere astrology. -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |
