Do The Met Office Know What Extreme Weather Really Looks Like?

by P. Homewood, Oct 5, 2023 in NotaLotofPeopleKnowThat


I have a prediction!

At the end of the year, the Met Office’s State of the Climate report will declare 2023 as a “Year of Extremes”.

It will highlight September as a particularly extreme month, with a heatwave (which peaked at temperatures several degrees lower than in 1906 and 1911); a monthly temperature no higher than in September 2006; and Storm Agnes.

I doubt whether anybody with any experience would find anything extreme about the weather last month. On the contrary, they will all be able to recall genuinely extreme autumn weather in the past.

For example, let;s look back to the 1960s, courtesy of Weatherweb:

A heatwave isn’t the end of the world

by T. Fazi, July 18, 2023 in UnHerd


As I write this, in my favourite local café in Rome, the temperature outside is close to 40°C. So yes, it’s hot. Yet, thanks to a relatively old invention — air conditioning — I’m able to work in comfort. The 10-minute bike ride back home will be tougher than usual, but it won’t kill me. Like most people here, I consider these temperatures to be a nuisance — but that’s about it.

According to the news, however, I should be terribly concerned — terrified, in fact. Everyone’s running headline stories about the “extreme”, “record-breaking” and “deadly” hot weather sweeping across Asia, the US and, most notably, Europe. Here, the heatwave was unofficially named Cerberus, the multi-headed dog that guards the gates of Hades, before being replaced by Charon, the man who ferries the dead there. Rome is being called the “infernal city”. To be honest, I can think of several much more hellish places around the world at the moment — cities plagued by poverty, terrorism and war. And yet we are told that the current heat waves are a taste of the “hell” that awaits us as a result of climate change.

Record Temperature In China Not All It Seems

by P. Homewood, Jul 18, 2023 in NotaLotofPeopleKnowThat


BEIJING, July 17 (Reuters) – A remote township in China’s arid northwest endured temperatures of more than 52 Celsius (126 Fahrenheit) on Sunday, state media reported, setting a record for a country that was battling minus 50C weather just six months ago.

Temperatures at Sanbao township in Xinjiang’s Turpan Depression soared as high as 52.2C on Sunday, state-run Xinjiang Daily reported on Monday, with the record heat expected to persist at least another five days.

The Sunday temperature broke a previous record of 50.3C, measured in 2015 near Ayding in the depression, a vast basin of sand dunes and dried-up lakes more than 150 m (492 ft) below sea level.

I can’t see the heatwave in Beijing particularly affecting that family crossing the road! Looks like they’re having a nice day out.

But back to Sanbao, which sits in the Turpan Depression that is as much as 150m below sea level. According to Wikipedia, the Turpan has a harsh desert climate, and is counted as one of the Furnaces of China. It is believed to be the second or third deepest depression on Earth. it is also the hottest and driest area in China during the summer.

Think it’s hot now? How Britain roasted in TEN-WEEK heatwave during summer of ’76

by P. Homewood, Jul 15, 2022 in NotaLotofPeopleKnowThat


Wildfires have raged, speed restrictions have been imposed on some railway lines and hospitals have already declared ‘critical incidents’.

The hot weather in Britain this summer is set to peak next week, when the mercury could top 39C (102F) in London.

The current non-stop sunshine has evoked memories of the summer of 1976, when there were 15 consecutive days that saw temperatures of 89.6F (32C) somewhere in the UK.

Overall, there were ten weeks of blazing heat that saw widespread drought, mass standpipe use, and even the pausing of the murder trial of the notorious ‘Black Panther’, after a woman suffering from ‘heat exhaustion’ collapsed.

During a First Division football match between Manchester City and Aston Villa, City player collectively lost four stone in weight, prompting the team’s captain to call for an end to ‘summer soccer’.

At that year’s Wimbledon tennis championships, umpires were allowed to remove their jackets for the first time in living memory, whilst major roads were littered with broken-down cars that had overheated.

The extreme weather also caused an increase in the number of 999 callouts to domestic disturbances, as tempers buckled due to the heat.

The summer of 1976 was caused in part by very hot air that had originated in the Mediterranean. The warm weather and lack of rain began on June 23 and did not abate for more than a month.

The highest temperature recorded in the summer was on July 3, when the mercury hit 96.6F (35.9C) in Cheltenham. The average maximum daily temperature was 67.8F (19.9C).

Températures extrêmes et foehn – Démonter le mythe des ‘dômes de chaleur’

by B. Van Vliet-Lanoë et J. Van Vliet, 27 août 2021, in ScienceClimat Energie


EN GUISE DE CONCLUSIONS

Les températures extrêmes observées en juin 2021 en Colombie britannique et dans le Nord-Ouest américain s’expliquent quantitativement et de manière classique par le gradient vertical de 9,8 K/km de l’adiabatique sèche, associé à une baisse d’altitude de 2 km, par l’intermédiaire d’un phénomène de foehn autocatalytique.Les concepts de « dôme de chaleur » et de Global Warming ne sont donc d’aucune utilité pour interpréter les observations. 

De manière plus générale, le phénomène de foehn peut être déclenché par la présence de hautes pressions dans le voisinage d’une chaîne de montagnes. La chaîne des Montagnes Rocheuses est particulièrement sujette à ces phénomènes depuis la Colombie britannique jusqu’à la Californie, mais elle est loin d’être la seule, comme le montre le Tableau 13. Le vent de foehn chaud et sec favorise également les incendies de forêts.

La genèse des hautes pressions peut résulter du passage d’ondes planétaires, mais également du passage d’AMP en provenance du vortex polaire. Ce dernier est particulièrement renforcé lorsque le vent solaire – ou l’activité aurorale qui lui est équivalente – faiblit, comme c’est le cas entre la fin d’un cycle solaire et la montée de l’activité du cycle suivant (Schlamminger 1990). Ceci explique pourquoi les hautes pressions et les vagues de froid sont particulièrement intenses au début du cycle solaire, comme déjà observé entre 2009 et 2013, et comme attendu entre 2019 et 2023. Il est donc probable que les phénomènes extrêmes et les incendies de forêts se poursuivront dans les 2 ou 3 années qui viennent. 

Enfin, les différents phénomènes physiques évoqués se situent non pas dans un contexte de réchauffement, mais bien dans un contexte de refroidissement global qui a démarré avec le 21ème siècle (van Vliet 2020) et que le printemps froid et l’été pluvieux de 2021 rendent particulièrement visible en Belgique, en France, en Angleterre et en Allemagne.

Dans cet article, une analyse quantitative simple nous a conduit à la conclusion que les températures extrêmes et les feux de forêt sont d’origine naturelle : l’homme n’y est donc pour rien, sauf pour la gestion de la couverture végétale et … l’allumage. Il est faux de juger l’homme coupable comme le font systématiquement l’ONU et le GIEC.

Oser prétendre que la transition énergétique améliorera cette situation relève d’une alliance contre nature entre le monde politique, le marketing insensé des énergies renouvelables et la propagande écologiste.

AUSTRALIA RECORDS ITS MOST SNOWFALL EVER OUTSIDE OF AN ALPINE AREA

by Cap Allon, August 25, 2020 in Electroverse


Antarctic air reaching Australia’s south east triggered snowfall down to low-lying regions across several states over the weekend and into Monday, with many people temporarily escaping house-arrest to enjoy the “once-in-a-15-year” event.

Heavy snow made for treacherous driving conditions near Old Adaminaby [Aug 23, 2020].

 

The town of Oberon received a record-breaking 20 cm (8 inches) of global warming goodness, the highest 24-hour snow total ever recorded outside of an Aussie alpine region. Traffic, predictably, was soon bumper-to-bumper through Hampton as tourists descended on Oberon to enjoy the snow–much to the chagrin of the local sheep. One Oberon resident reportedly bleated: “Let’s all go mingle with people from hot spots then risk taking something home. It will be so worth it.” And another jumbuck added: “I wonder what part of STAY AT HOME do all those idiots not understand.”

Flaming June? Hardly

by P. Homewood, July 1, 2020 in NotaLotofPeopleKnowThat


Phew, what a scorcher?? Hardly.

Despite the hype of the last week, the average temperature in England last month was pretty ordinary.

https://www.metoffice.gov.uk/hadobs/hadcet/data/download.html

According to the Central England Temperature series, June 2020 was only the 59th warmest on record.

Not only were the four hottest Junes prior to 1900, no June since 1976 has been in the top 17.

Met Office Does Not Know What “Extreme Weather” Is.

by P. Homewood, March 9, 2020 in NotaLotofPeopleKnowThat


https://www.metoffice.gov.uk/about-us/press-office/news/weather-and-climate/2019/weather-overview-2019

According to the Met Office, 2019 was a year of weather extremes in the UK. There is actually very little evidence to back this claim up, but this does not stop them ludicrously claiming one mild day in February as “extreme”!

To most people, extreme weather would be the sort of stuff our ancestors experienced in this very week in 1891:

How a 24-DAY heatwave on Australia’s east coast in January 1896 saw temperatures climb to 49 degrees and killed 437 people

by Freya Noble, February 14; 2017 in DailyMail

There were temperatures above 119F (48C)

It was a hot start to 1896 and by January 14, newspapers were reporting people were dying from a range of complications brought on by the extreme temperatures.

By the third week of the year, 12 infants had died from heat-related illnesses in Goulburn, NSW, alone, a report on JoNova about the heatwave revealed.

People were fleeing the cities on trains to seek refuge in the mountainous regions of the country, and one child escaping the heat ‘died at the moment the train arrived’.

Hospitals were at breaking point, and the death toll was rising.

 

How a 24 DAY heatwave in January 1896 saw temperatures hit 49 degrees and killed 437 people t is as if history is being erased. For all that we hear about recent record-breaking climate extremes, records that are equally extreme, and sometimes even more so, are ignored.
In January 1896 a savage blast “like a furnace” stretched across Australia from east to west and lasted for weeks. The death toll reached 437 people in the eastern states. Newspaper reports showed that in Bourke the heat approached 120°F (48.9°C) on three days (1)(2)(3). The maximumun at or above 102 degrees F (38.9°C) for 24 days straight.
By Tuesday Jan 14, people were reported falling dead in the streets. Unable to sleep, people in Brewarrina walked the streets at night for hours, the thermometer recording 109F at midnight. Overnight, the temperature did not fall below 103°F. On Jan 18 in Wilcannia, five deaths were recorded in one day, the hospitals were overcrowded and reports said that “more deaths are hourly expected”. By January 24, in Bourke, many businesses had shut down (almost everything bar the hotels). Panic stricken Australians were fleeing to the hills in climate refugee trains. As reported at the time, the government felt the situation was so serious that to save lives and ease the suffering of its citizens they added cheaper train services:

Lingen Cheated: Germany’s New All-Time Record High Resulted From DWD Weather Service Lousy Station Siting

by P. Gosselin, July 28, 2019 in NoTricksZone


During last week’s record-setting European heat wave, Germany’s previous record of 40.3C was impressively shattered by the measurement station located at the northwest city of Lingen, near the Dutch border, some 50 kilometers from where I live. The German DWD weather service and media loved it!

Controversial siting

Yet, controversy now swirls about the new record setting measurement since it has come to light that the measurement is fraught with some considerable siting issues.

As the photo published by T-online here shows, the station is located right near a DWD office building, is shielded from the wind by grown trees and is located not far from a public swimming pool.

Meteorologist Michael Theusner told t-online.de: “The monthly average of the daily highs in Lingen has been deviating more and more upwards from the average of the highs in Lower Saxony since 2010.” The station has become increasingly shielded and thus tends to heat up more.

Swiss veteran meteorologist Jörg Kachelmann wrote the extra heat possibly could be heating the station by up to another 3 degrees!

DWD accepts overheated reading

New February Temperature Record At Kew–But Is It Evidence Of Climate Change?

by P. Homewood, February 27, 2019 in NotaLotofPeopleKnowThat


 

But let’s take a closer look.

Daily temperature extremes are not especially meaningful in themselves.

If global warming is responsible for yesterday’s record , was it also responsible for the record January temperature set in 1958? Or in March 1968, April 1949, May 1922, June 1957, September 1906 or December 1948, when records, which still stand, were also set?
