Gravesend 32.3C, why so hot?

Posted: July 19, 2014 by tchannon in weather

The Met office Gravesend weather station is a little notorious as runs hot in what is the hottest part of the UK where there is a lot of history over dubious temperature measurement. (some findings yet to be revealed)

This Gravesend station is one of the few which regularly tops daily readings. I was prepared so I ran a capture of the Met Office web site hourly data for England, numbers are then plotted here. No better information is published, nor is this a full weather station, a subset.

What happened turns out to be interesting.

July snow has closed several Swiss passes, as Gosselin puts it

German meteorologists point out that snow at such elevations at this time of year are not unusual. Well, if the “usual” is happening, then the climate can’t be changing that much.

20 inches of snow.

Greenhouse effectsFollowing on from our recent debate on the likely extent of the greenhouse effect on Earth, this post will broaden the scope of discussion by allowing consideration of planetary surface temperatures on imaginary worlds. Tim Folkerts proposes a world at the distance from the Sun of our moon (i.e. the same average distance as Earth), with a twist on surface composition:

Konrad,

Just out of curiosity, if I put a ball of water — say a few km in diameter — in some sort of clear plastic baggie to keep it together and prevent evaporation in orbit around the sun @ 1 AU, are you claiming the water inside the baggie will be at least 80 C everywhere?

Or if I put a series of such plastic baggies on the moon to cover the entire surface with water 1 km deep that cannot evaporate, that the surface of the moon would be at or above 80 C everywhere (lets even limit the question to the “tropics” out to ~ 30 degrees N & S to avoid question about what happens at the poles)?

(We could even make the baggie slightly elastic to apply 1 Atm of pressure inward on the ball of water).

____________________________

Tim appears to have misunderstood what Konrad and I are telling him about the atmosphere being a cooling agent rather than a warming agent, and how pressure acts to slow the loss of energy from the oceans via the atmospheric suppression of evaporation and the increased density of a near surface atmosphere, which is not present on his toy planet.

BBC spends £500k to ask 33,000 Asians 5,000 miles from UK what they think of climate change: Corporation savaged for ‘astonishing’ campaign survey on global warming
David Rose – Sun 29th June 2014

bbc-greenpeace-medThe BBC has spent hundreds of thousands of pounds of taxpayers’ money asking 33,000 people in Asian countries how climate change is affecting them.

The £519,000 campaigning survey by little-known BBC Media Action is designed to persuade the world to adopt more hard-line policies to combat global warming.

It was immediately condemned yesterday as a flagrant abuse of the Corporation’s rules on impartiality and ‘a spectacular waste of money’ by a top academic expert.

Every year, BBC Media Action gets £22.2 million from the taxpayer via the Foreign Office and Department for International Development.

BBC Media Action has a £40 million annual budget, and the proportion not funded by the taxpayer is paid  by the European Union, the Bill & Melinda Gates Foundation, and the US government.

Pierre L. Gosselin provides an English overview of a video presentation in German given by Dr. Sebastian Lüning, a geologist and co-author of the book “The Neglected Sun

This is a geological context that unfortunately is lost on many people like physicists who believe their formulae more than they believe the true facts.

Pierre mentions “All graphics cropped from Lüning’s presentation with permission.” so I won’t copy them here.

A few years ago, I started a wikipedia page on the Gore Effect; the uncanny phenomenon which unleashes snow, hail, torrential rain, icy winds and sleet on the venues where Al Gore is speaking about global warming. The instances are too numerous to list. My page got deleted within a few months by the usual suspects. But it was reborn when another wiki user put up a much more detailed and better referenced version, and I thought it unassailable. But no, the usual suspects are at it again:

David Archibald’s prediction for global average temperature 2014-2025

David Archibald’s post at Quadrant.org.au has stirred some interesting debate here at the talkshop. David predicts an imminent and steep drop in regional temperatures as a result of the slowdown in solar activity seen since the descent of solar cycle 23 in 2003. It’s not the first time he has made such predictions. As Nick Stokes pointed out in discussion, Archibald told the Australian senate committee in 2009 that temperature was about to go down at a scary 0.2C per annum. It didn’t happen. But David says it’s different this time, because a decade has passed since solar cycle 23 dropped towards a long minimum, followed by the weak cycle 24 we are currently in. The decadal lag is implied by David Evan’s new hypothesis which identifies a ‘notch filter’ which points to a cycle-long lag between changes in solar activity and the effect becoming visible in the terrestrial response. David goes on to predict that due to Penn and Livingstone’s prediction of a very low sunspot number in cycle 25, we are headed for drastic cooling.

There are several points on which I disagree with David’s analysis, and I’ll cover them below the break.

(more…)

David Archibald has some form for making dire predictions of imminent global cooling. His latest, including a forecast he claims uses David Evans’ ‘Notch delay climate model’  has just been published online at Quadrant.org.au and makes scary reading. At one level, you could be forgiven for thinking that his doom laden prognosis is as alarmist as those of Al Gore or James Hansen. However, it behoves us to remember that unlike the global warming alarmist’s fear of frying, history backs up the existence and dire effects of sudden cooling events. Personally, I think the coming cooling is unlikely to be as sudden or deep as David fears, but I’ll leave my reasoning for that opinion for the comments section. Strap in and read on.

Excerpts from: 

The edge of a cold, deep abyss?
David Archibald 25-6-2014

One of the best predictions of climate ever made (weighted for distance and accuracy) was by two Californian researchers, Leona Libby and Louis Pandolfi.  In 1979, they used tree ring data from redwoods in Kings Canyon to make a remarkably accurate forecast1.  From a Los Angeles Times interview of that year,

When she and Pandolfi project their curves into the future, they show lower average temperatures from now through the mid-1980s.  “Then,” Dr. Libby added, “we see a warming trend (by about a quarter of 1 degree Fahrenheit) globally to around the year 2000.  And then it will get really cold—if we believe our projections.  This has to be tested.” 

How cold? “Easily one or two degrees,” she replied, “and maybe even three or four degrees.”

Thanks to commenter ‘psc3113′ for finding the concluding part of HC Russells’ paper on a lunar 19 year cycle in drought records, taken from The Queenslander (Brisbane, Qld. : 1866 – 1939)  Saturday 4 July 1896. At the conclusion of the article, the probably cause of the 19 year cycle identified is elucidated.

Periodicity of Good and Bad Seasons
MR. H. C. RUSSELL’S THEORY.
(Continued from last Week.)

Hurricanes Come in Droughts.
I should like it to be clearly understood that I do not mean ordinary hurricanes, which are as much parts of ordinary weather conditions in some parts of the world as our southerly winds are here. What I mean are extraordinary hurricanes, those that come at long intervals to terrify mankind by their power for destruction. These are connected with droughts, and, therefore should be discussed here. I had long since observed that the connection between the two was obvious enough sometimes, and during the past year I was reminded of it very often by the frequent reports of heavy gales met with by ships coming to this port, indicating great atmospheric energy. Then on the 3rd January, 1803, came the hurricane over the Tongan group of islands, and not one of the vessels in the harbour rode out the storm; every one of them was wrecked in the harbour before morning, and the wind was of such exceptional violence that after it was over the islands looked as if they had been bombarded.

Then I turned to storms on this coast, some of which were of terrible violence. And as I write, the 28th ‘May, we have the report of a terrible cyclone in America, by which three of the States, Missouri, Illinois, and Indiana were damaged and the city of St. Louis wrecked. and 1300 people killed by falling buildings, and damage to property caused to the extent, estimated, of twenty million dollars; another fragment of the present D drought.

While browsing Ian Wilson’s excellent Astro-Climate Connection blog, I found a graphic showing the coincidence of El Nino with the alignment of the Lunar line of nodes (declination cycle) and line of apse (orbital precession), with the Sun. I’ve taken the liberty of adding my Solar – El Nino hypothesis to it: the proposal is that El Nino tends to be initiated as the cycle starts to decline steeply and initiated again at solar minimum as it ‘bottom’s out’. I’ll reproduce Ian’s accompanying text below the break but to get to the point, here’s  the result:

From Ian Wilson’s Astro-Climate Connection blog:

rranom.vic.0112.19917

The Moon’s orbit is tilted by approximately five degrees compared to the Earth-Sun plane. The net affect of this is that the strength of Lunar-tides at a given latitude on the Earth’s surface vary in strength over a cycle of 18.6 years. This 18.6 year Draconic cycle is also clearly evident in the small changes that take place in the rate of rotation of the Earth.

The Nineteen Year Weather Cycle—Diagram Illustrating Mr. H. C. Russells Paper on ” The Periodicity of Seasons”

The paper lately read before the Royal Society of New South Wales by Mr. H.C. Russell, the Government Astronomer, a condensation of which has already appeared in the ” Queens lander,” has excited so much interest and so much discussion that no apology is needed for returning to the subject. With the view of affording our readers as full an insight as possible into the grounds upon which Mr. Russell has based his conversion to the theory of the nineteen-year cycle we reproduce the complete paper, as published in the ” Sydney Mail,” with the accompanying diagrams.

Mr. Russell said :— I feel some reluctance in coming for ward to-night with the result of my investigations into the periodicity of good and bad seasons—floods and droughts if you will—because they must come to you as a surprise, and they will make a claim on your confidence which at first sight you will probably not be disposed to grant. For myself, I know that some years ago, if anyone had come to me, stating that it was possible to forecast the seasons many years in advance, I should have received the statement with incredulity, and an inclination to think lightly of the man who advanced such views.’

I’m of the opinion that before getting into the complexity of numerical modelling, it’s wise to put considerable effort into trying to understand the physical processes at work in the climate system, and the origins of the energy flows that drive them. David Evans’ recent series of posts over at Jo Nova’s site have generated a lot of interesting discussion (despite being roundly ignored by Anthony Watts at WUWT), and I think we can shed some light on the ‘mysterious 11yr lag’ between solar input and climate response.

Pierre L. Gosselin reports on a Spiegel Online article

Models Wrong Again…Sea Ice Break-Up Caused In Large Part By Storm-Generated Oceanic Wave And Wind Dynamics!

By P Gosselin on 31. Mai 2014

Spiegel science journalist Axel Bojanowski has a fascinating piece on what likely causes most of the sea ice to break up. The Spiegel introduction:

Sea ice is disappearing in the Arctic, around the Antarctic it is growing – today’s conventional climate models are unable to explain this contradiction. One effect has just been measured by sensors: wave motion is able to crack ice, hundreds of kilometers away.”

Don’t think this is supposed to happen but local global warming allows for local global cooling, any oxymoron going.

The BBC reports – laced with the inevitable ‘warmist catchphrases’ – a trend in weather phenomena described in a recent research paper.

No surprise to find this:
‘The researchers believe humans are influencing the changes’
(but they haven’t found the mechanism)

or this:
‘There is compelling evidence that the expansion of the tropics is attributable to a combination of human activities, but we don’t know which is the primary factor.’

How compelling is that? It’s hard to keep a straight face.

Evidence of a direct relationship between the Sun and the weather – apart from the obvious – has been found by a research group.

Quote: ‘scientists found that when the speed and intensity of the solar winds increased, so too did the rate of lightning strikes.’

That raises the issue of cyclical weather events driven by the Sun.

ON THE SECULAR VARIATION OF RAINFALL AT ADELAIDE

E.A CORNISH (CSIRO Adelaide)

Summary

A detailed analysis of the rainfall of Adelaide has established that periodic changes occur in the incidence and duration of the winter rains. These changes have a period and amplitude of approximately 23 years and 30 days respectively, and superimposed on them is a long-term trend which is manifested by protraction of the latter half of the season, spring rains now occurring about 3 weeks later than they did just over 100 years ago. The total quantity of rain precipitated has shown no statistical significant changes.

Rainfall 1766 onwards

Posted: April 27, 2014 by tchannon in Analysis, climate, Natural Variation, weather

mo-1766-general-small

Since oldbrew nicely points at Paul Homewood I am taking the opportunity to add a quick post.

I am very close to posting an article on the 17 rainfall data series from 1910 onwards, been working on this since January, took half hour to drop in the long Met Office England and Wales time series 1766 onwards.

I post an output without much explanation.

If you want to really look the PDF is much better provided you know how to magnify, you can zoom in on the timeseries plot. No actual markers, keeps the file size down.

Back in February, Julia Slingo, the Met Office’s Chief Scientist, was reported by the BBC, when discussing the recent wet winter, as saying:

The UK had seen the most exceptional period of rainfall in 248 years….

We have records going back to 1766 and we have nothing like this. We have seen some exceptional weather. We can’t say it is unprecedented but it is exceptional.

There was no definitive answer to what caused the storms, but all the evidence suggests there is a link to climate change

I pointed out at the time that these statements simply were not supported by the data, and asked the Met Office to justify them. (Remember that this report was on 9th February, so she only had Dec/Jan data to go on). After three attempts on their part to sidetrack the issue, they have totally failed to back…
