This article is cross posted from Tim’s blog as of interest to some Talkshop readers with a few extra sentences likely to raise discussion. 

August 2014 there was a meteorological gift of both exceptional conditions and good data. What can be learnt?

Three Met Office sites showed a signature of exponential cooling. This requires clear sky and a calm. Given somewhat limited parameter hourly data the following shows the commonality. The computed terminal conditions are shown later in this article.

Benson and Santon Downham data has been normalised to Katesbridge[3], which has the least noisy data or the three.

Achieving a close overlay requires taking earth rotation into account, dusk and dawn move relatively both by geographic location and the peculiar movement throughout the year as night length changes, these do not move together [1]. Fractional delay (less that the sample period) was used to equalize diurnal time. (see the two blog articles here)

Dusk appears to be the important factor, a surprising finding, I assume cooling is time from dusk, dawn terminates cooling.

General information, under essentially calm conditions wind drops for a period during the night then reappears just after dawn. (not shown here)

Temperature normalisation defined is for the cold period, not as accurate for Benson where the better site exposure (more open) led to more wind at times.

August 25, 1814

The clouds began to swirl and the winds kicked up. A tornado formed in the center of the city and headed straight for the British on Capitol Hill. The twister ripped buildings from their foundations and trees up by the roots. British cannons were tossed around by the winds. Several British troops were killed by falling structures and flying debris.

 

The rain continued for two hours, dousing the flames. The British decided it was time to leave.

The lady answered, “No, Sir, this is a special interposition of Providence to drive our enemies from our city.”

Some say money can buy brains, brains are cheap. Duffers think that, make the mistake of confusing rote with The Spark. As a wit said ‘the most intelligent person in the room is the room’… to which I add, buying others to inside still leaves the room. Self selection is recursive.

There again for here, an oscillation does not explain itself. Small step first.

Joe Bastardi is writing sense, Gosselin runs with it.

A Single Meteorologist Explains What $165 Billion In Government-Funded Climate Science Couldn’t

Large scale oceanic oscillations responsible for most of the post 1980 “warming”

By Joe Bastardi

I think global warming is a misnomer.

There is a distortion of the temperature pattern on the globe, brought about by the natural cyclical warming events of the warm PDO and warm AMO together. I spoke about this at Heartland a couple of years ago – how the sea ice increase in the south and the decrease in the north were the hidden message that here is no “warming” just a distortion.

We have an August frost, 0.0C mean at 3am BST

Posted: August 24, 2014 by tchannon in weather

Quick post by Tim

Katesbridge is fascinating, edge of marsh in Northern Ireland (see surfacestations, top menu), it can be very cold. Benson, south of England is down to 4C, a cool night with I suspect a touch of ground frost widely. Hopefully not enough to damage sensitive garden plants. (I have the numeric data here)

For me this is a fascinating moment, been working on an evolution of capturing and presenting UK Met Office data. First usage was literally a few minutes ago, manually grabbed the data, get get and then typed regen, it figured out what needed doing, worked.

This is worth a look just for the last paragraph, which undermines most of the rest of it. Under the optimistic sub-heading ‘Warming to recommence’ we find:

‘Despite the warming hiatus, Knutti is convinced there is no reason to doubt either the existing calculations for the climate activity of greenhouse gases or the latest climate models.’

“Short-term climate fluctuations can easily be explained. They do not alter the fact that the climate will become considerably warmer in the long term as a result of greenhouse gas emissions,” says Knutti.

‘He believes that global warming will recommence as soon as solar activity, aerosol concentrations in the atmosphere and weather phenomena such as El Niño naturally start returning to the values of previous decades.’ [bold added]

Translation: as soon as the sun, the weather and volcanoes – all natural factors – allow, the world will start warming again. Who knew?

Good to hear a warmist trashing his own theory in order to explain the lack of temperature rise this century – without realising it.

Long-range weather forecast for UK reveals 2014 will be a SCORCHER!
BRITAIN is set to roast in a THREE-MONTH heatwave that could smash ALL summer weather records, forecasters claimed tonight.

That was not the Met Office, wise. Couple of days ago (maybe 17th August) there was muttering about a ground frost in a few places if the wind falls light. Wind has been pulling in Artic air for some days now.

Night 17th/18th Exeter Airport dropped to 5.8C, far south west of England. Previous night Breamar Scotland 8.8C, traditionally the coldest place.

Central heating here wanted to trip on first thing in the morning over the past few days, mean temperature outside well below setpoint.

There is an unfolding disaster in the poor regions of central America from sustained drought.

I am reluctant to make much of a story involving people in trouble, it is however a good news matter if a needless focus on the daft has gone, focusing instead on where it matters. Put the effort there.

El Nino, which can last more than a year, significantly raises surface temperatures in the central and eastern areas of the tropical Pacific Ocean, a phenomenon linked to major climate fluctuations around the world.

hh-p3Image from NOAA press release

NOAA operate a number of hurricane hunter aircraft including three venerable P3-Orion turboprops for low level long duration surveillance.

Taking two out of service for maintenance work as the peak of the hurricane season approaches looks remiss.

I suppose that depends on the true role in 2014 in an era of satellites, radar and alternate aircraft. However according to wikipedia there is also the USAF 53d Weather Reconnaissance Squadron  flying into tropical storms, perhaps that is sufficient.

There again perhaps NOAA believe the season will be quiet… NOAA superstitious? That’s more like it, remove resource, the gods respond.

Piers Corbyn has made a weather forecast. Nothing new there, that’s his line of work. But this one has caught the attention of at least one organ of the UK national press [warning: loud headline ahead]…
Daily Express report

Reading the forecast, it clearly states the behaviour of the jet stream is the key factor. So what are the chances of showing any significant link between the behaviour of jet streams and small variations in atmospheric trace gases? They appear to be remote at present.

Visit Cartoons by Josh and buy something

From RT.com

The UK risks sweeping electricity blackouts unless it increases the state’s capacity to balance infrequent supply from renewable energy sources, a prominent engineer who carried out government-funded research has warned.

While British authorities are under legal obligation to source almost a third of their electricity from renewable sources such as solar and wind by 2020, they require immediately deployable gas-fuelled power stations to cater for inevitable lulls in sun and wind energy output.

Hugh Sharman, a British engineering consultant, was commissioned to work on a government-sanctioned report examining how UK authorities could sustain the nation’s energy demands in an era of mandatory renewable energy use.

Tendered to the Department for Energy and Climate Change (DECC) last year, the research went unpublished.

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)

Image

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.

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.
