India Wilts Under Heatwave as Temperature Hits 50 Degrees Celsius

https://phys.org/news/2020-05-india-wil ... grees.html

India is wilting under a heatwave, with the temperature in places reaching 50 degrees Celsius (122 degrees Fahrenheit) and the capital enduring its hottest May day in nearly two decades.

The hot spell is projected to scorch northern India for several more days, the Meteorological Department said late Tuesday, "with severe heat wave conditions in isolated pockets".

Met officials said Churu in the northern state of Rajasthan was the hottest place on record on Tuesday, at 50 Celsius, while parts of Punjab, Haryana and Uttar Pradesh sweltered in the high 40s.

Parts of the capital, New Delhi, recorded the hottest May day in 18 years with the mercury hitting 47.6 Celsius.

The country of 1.3 billion people suffers from severe water shortages with tens of millions lacking running water—to say nothing of air conditioning.

Parts of Delhi and elsewhere regularly see scuffles when tankers arrive to deliver water. Last year Chennai made international headlines when the southern city ran out of water entirely.

The heatwave adds to problems the country already has dealing with the spread of coronavirus.

India now has the 10th highest number of coronavirus cases globally, climbing above 150,000 on Wednesday with almost 4,500 deaths.

Last week cyclone Amphan killed more than 100 people as it ravaged in eastern India and Bangladesh, flattening villages, destroying farms and leaving millions without power.

Huge swarms of desert locusts, meanwhile, have destroyed nearly 50,000 hectares (125,000 acres) of crops across western and central India, and may enter Delhi in coming days.

The north-eastern states of Assam and Meghalaya are also currently experiencing floods, with more heavy rainfall forecast in the coming days.

Much of Western Europe is anomalously hot for this time of year. Anyone there who can tell us how it feels on the ground?

Spain Sets Temperature Records, UK Sees Hottest Day of 2020


https://phys.org/news/2020-07-spain-tem ... t-day.html

San Sebastian on Spain's northern coast witnessed 42 degrees Celsius (107 degrees Fahrenheit) on Thursday—the hottest temperature there since records began in 1955, the national weather agency said.

The city of Palma, on Spain's Mediterranean island of Mallorca, set a local record of 40.6 degrees Celsius (105 degrees Fahrenheit) on Tuesday.

... To the north, U.K. residents sought shade as temperatures rose above 37 degrees Celsius. National weather agency the Met Office said a reading of 37.8 degrees Celsius—100 degrees Fahrenheit—was recorded at Heathrow Airport west of London. That made Friday the hottest day of 2020 and the third-hottest on record.

From Britain to Italy, temperatures around 40 degrees Celsius (104 Fahrenheit) made face masks almost unbearable for many, as more cities begin requiring them outdoors to prevent surges in COVID-19 cases.

Austria and Bulgaria also reported their hottest day yet this year, with Vienna topping 37 degrees before a summer storm brought some relief.

Sexy Heat on for a moment, easy come, easy go

For a report on the ground, my lowlands....

A very short spike for Northwest Europe but it looks like the true heatwave will set in at the end of next week.
North African heat will dominate our region, maybe for weeks, we'll have to see how it works out.

Thanks you D. for keeping an eye on our surroundings, watching our backs :-D

Thing is, it seems the usual depressions that bring rain and moderation, are more and more stuck on the atlantic. It is getting harder to predict the weather and even seasons. SST is everything for a grain based society. :cry:

On a side note,
It looks like the select few A-holes dominating homo sapiens will meet their end before we the people do, justice served:

https://onstellar.com/blogs/148138/X22- ... -Hot-Month

X22 is banned from youtube, information warfare......silent WW3.
WWG1WGA.
I think Q is Cid, cannot prove it but Q has the same style teaching. Heart at the right place and that is all that matters.
That and the amount of personal power that you are, that you save and gather, a hunt for power, for freedom.
There are certain people, fearless and diciplined, with personal power that choose the dark side, to hunt them is big game, far more dangerous than the usual petty fry, politicians, kings and billionaires. The dark lords, the direct link between dark forces guiding humanity, their stongest weapons, near immortal yet corrupt to their bones.
I just cannot stand them, the devil and demons are just inorganic predators and we are their food, we are the livestock, they are the farmers. It is the people that knowingly and willfully sold their souls I cannot stand.

There are special forces now teaming up to hunt them, their paid armies/helpers down, there will be no mercy after people are shown what crimes they have done, how many millions, woman and children they have destroyed, crimes against humanity :twisted: Enough is enough.

Last month:

France was also experiencing its first heatwave with temperatures in the mid-30s. That is usual for the height of summer in the country - around August - but not the beginning of the season, said climate NGO CARE.
"Over the past few years, we have noticed heatwaves arriving ever earlier, everywhere in the world," it said in a statement, blaming global warming.
"A few days ago, a temperature of 38C (100F) was recorded north of the Arctic Circle. Such high heat phenomena could be twice as frequent by 2050, so we must expect summers to be ever longer and hotter, and therefore more deadly."

The World Meteorological Organization (WMO) said it was verifying the worrying temperature record for Siberia.
The WMO warned people to avoid exposure to the sun or temperatures higher than 25C (77F) "as there is no evidence that this prevents or cures COVID-19, and it increases your risk of sunburn and heat-related illness".

Thanks for that perspective, wf.

It was quite a warm winter in the lowlands, again because of sst. Did that throw of agriculture much?

Good point about increased difficulty predicting weather or even seasons. We're seeing that more and more in the north country of the US, too

Dutch drought

Unread postby Whitefang » Sun 02 Aug 2020, 03:55:49

Yes D, agriculture is under stress but still working.
We are having a lack of rain, especially the East side on the German border.
Recent study on water management, looks like the issue will be controlled with gradual CC.

https://www.climatechangepost.com/netherlands/droughts/

Present supply and demand
Water supply in an average year is about 3000 mm. In the extremely dry year of 1976 it was 40% less. About 60% of the fresh water supply in the Netherlands comes from the river Rhine, 30% is precipitation and 10% stems from other rivers. On a yearly basis,60 to 80% of the river supply is discharged into the sea, depending on the drought conditions of the year. Even though this water is not used for agriculture f.i., it has a function though: to avoid salt intrusion in the river outlets, and to maintain a sufficiently deep navigation channel in the rivers (1).

In an average year 20%, and in a dry year 30% of the available amount of fresh water is evaporated, mostly by agriculture (55% of the surface area in the Netherlands is used for agriculture). The other interests that use fresh water (industry, drinking water supply), use three times as much in a dry year with respect to an average year; even during a dry year this amounts to less than 10% of the total water demand. 55% of the drinking water supply stems from groundwater, 45% from surface water. The annual fresh water production in the Netherlands is 1250 million m3, of which a small part is used by the industry (2).

In an average year the total shortage of water supply for all the interests at stake is 5 million m3, which is 0.16 mm of water covering the entire country. In an extremely dry year the shortage of supply is 90 million m3 , which is 2.7 mm of water covering the entire country. The shortage of ground water in the root zone of the plants is much larger and may be up to 5.5 billion m3 in an extremely dry year. This amount agrees with a 4.5 metre water depth of the lake IJsselmeer, which is one of the largest fresh water lakes of Europe (1).

Future supply and demand
Different climate change scenarios show different impacts on future water shortages. Two extreme scenario’s have been analyzed with respect to future droughts in the Netherlands. A scenario with modest climate change indicates that water shortages in 2050 may be quite similar to the present situation. A scenario in which the climate changes fast shows a 16% increase of evaporation and a 20% reduction of precipitation in the summer; this change may be twice as large in 2100 (2). An increase of water shortage in dry summers seems likely in the next 50 years. Low river discharge in dry summers will probably also reduce; for the Rhine a significant reduction is expected only after 2050, however (10).



The Rhine river supply turns out to be the key, if the whole of NW Europe dries out, we the Dutch will be in trouble.
Predictions with abrupt CC make the Sahara jump club med turning the Alps into the high Atlas.......the source of our fresh water.

Thanks for the info. Do they have de-salination plants? Are they looking at building some (more)?

Low on salt

https://www.sciencedirect.com/science/a ... 6400801940

Abstract
Substantial industrial development along the Scheldt estuary in the extreme south-west of the Netherlands has led to an increased demand for water and electricity.
In 1965 the authorities realized the favourable conditions prevailing for combined sea water distillation and electric power production.

The initiative for commercial negotiations was taken by the Electricity Board for the Province of Zeeland. In October, 1966, Werkspoor-Amsterdam N.V. received the order for 2 multi-stage flash-evaporating plants with a designed unit capacity of 14,500 m3 (3,850,000 US gallons) of fresh water per day. These plants, believed to be the largest now under construction, are scheduled to start operation in October, 1968.

I did not expect such a plant to be so close to my hometown Roosendaal, from the late 60's though.....
Next week a heatwave, starting thursday, we'll be checking out Zoutelande at the Dutch Riviera, my favourate beach since I were two years old.
Earthnullschool reads 30 degrees C at CAnadian Archipel, that must count as a heatwave, 66 degrees NL.

Greenland ice sheet heat

Unread postby Whitefang » Thu 06 Aug 2020, 05:35:04

https://earth.nullschool.net/#current/w ... 918,72.776

Almost 11 degrees C surface temp. right on top of the GIS.
It should be freezing, even in the dead of summer.
That heat dome will move over western Europe, the heat is on.
Or maybe the heat already moving into Europe extended into the Northwest corner, Iceland and further.

Well, Arctic amplification is now here in a big way. The Arctic is warming at roughly twice the rate of the globe as a whole. When extreme heat waves like this one strike, it stands out to everyone. Scientists are generally reluctant to say "We told you so," but the record shows that we did.
As director of the National Snow and Ice Data Center and an Arctic climate scientist who first set foot in the far North in 1982, I've had a front-row seat to watch the transformation.


More at place with the arctic thread but since all is connected:

A new month begins today, and at the moment it looks as though it’s going to be the most interesting one since August 2012. Here once again is the satellite image of the enormous cyclone that was spinning over the Beaufort/Chukchi Seas just a few days ago:


Plus the current open water north of Greenland. Perhaps once Polarstern has been flushed out into the open water of the Fram Strait at the end of the MOSAiC expedition she could take another look at this almost completely unexplored area of the Arctic Ocean?


The GIS heatwave will enlarge the gap, warm air flowing down flash melting the slush that is left.

PIOMAS gridded thickness data is updated to day 213 (31Jul/1Aug). The (calculated) volume on that day was 6.52 [1000km3], second lowest (behind 2019).

superheatwave

Unread postby Whitefang » Mon 10 Aug 2020, 11:55:48

Limburg, a province down the southeast measured a superheatwave, 3 days of plus 35 degrees C. and 5 days of plus 30.
Only happening since this century, first in 2003, then 2015 and every year since 2018.
This year the warmest heatwave ever.
That is a pattern.

https://www.dutchnews.nl/news/2020/08/h ... res-ahead/

The Netherlands is in for a heatwave over the next six days at least, with temperatures reaching the low 30s Celsius, accompanied by plenty of sunshine. There could be some cloud around by Sunday, but in the main it will be hot and sunny nationwide, with temperatures up to 29 Celsius in the north and 34 Celsius in the far south, the KNMI weather bureau said. At night, the temperature will drop to between 17 and 20 Celsius, offering some respite from the day’s heat.

Read more at DutchNews.nl:


Here you go:
https://nltimes.nl/2020/08/06/good-chan ... etherlands

For a stretch of hot weather to qualify as a heatwave, there must be at least five days of maximums above 25 degrees Celsius, three of which must be above 30 degrees. For a super heatwave, there must be five consecutive days of temps above 30 degrees, including three with temps above 35 degrees.
If this heatwave turns into a regional super heatwave, it will be the third consecutive year that parts of the Netherlands experienced such high temperatures.
For a national heatwave or super heatwave, the above mentioned conditions must be met at the national weather station in De Bilt. The Netherlands has never had a national super heatwave, though came close to it last year.
With the current weather predictions, this national heatwave will be a fact on Sunday. It will be the 29th national heat wave since the Netherlands started keeping track of temperature measurements in 1901.

Hot NW Europe

Unread postby Whitefang » Tue 11 Aug 2020, 08:34:17

Thanks D,

Heat for me and family is a minor issue, pool at the backyard....... 8)
I feel sad for my mom passing away, sudden and unexpected brainfailure, a week in coma before we pulled the plug.
Same death my dad had last spring, but his death were welcome at the last phase of Altzheimer's.
At least my mom does not have to deal with a slow decent into Parkinsons misery, but I had plans to live/travel with her to Morocco/North America and Europe by camper, the sun bird thing.
I miss her, both of them.
I thought we had time left to spend, I were wrong, that were a mistake :cry:
A stupidity to assume you have time, to live like an immortal being, as if death will never touch you.
At least my parents lived very close to my house, 20 min.by bike....they witnessed my children growing up first hand.

Back to a hot topic:
https://en.wikipedia.org/wiki/2020_European_heat_wave

Belgium
On 31 July, much of the country exceeded 35 °C (95 °F). Temperatures up to 36.5 °C (97.7 °F) were recorded in Brussels.[1][2] On 7 August, 10 Regions in Belgium were put under a red heat wave bulletin by the Royal Meteorological Institute with the majority of the country forecasted to exceed over 32 °C (90 °F).[3]

France
France is one of the most affected countries during the heatwave, with much of the country exceeding 35 °C (95 °F) and the majority of Central and Northern France exceeding 38 °C (100 °F) on 31 July.[4] Paris recorded temperatures up to 39.5 °C (103.1 °F) at Orly Airport and Le Bourget Airport.[5][6]. Coastal areas in Hauts-de-France have also exceeded 38 °C (100 °F) on 31 July. Temperatures as high as 37.9 °C (100.2 °F) at Boulogne-sur-Mer,[7] beating the previous record of 36.4 °C (97.5 °F) recorded the year before on 25 July 2019.[8].

Temperatures in France have cooled down considerably during the start of August until 5 August where temperatures began to rise again. On 6 August, much of the country exceeded 32 °C (90 °F). On August 7, 45 departments were included in an Orange heat wave alert by MétéoFrance. Much of the country is forecasted to exceed 35 °C (95 °F).[9][10]

The Netherlands
On 31 July, temperatures as high as 36.7 °C (98.1 °F) were recorded in Westdorpe.[11] On 7 August, 4 Provinces in the South of the Netherlands were put under a Code Orange warning for extreme heat. The majority of the Netherlands is forecasted to exceed 32 °C (90 °F).[12]

United Kingdom
On 31 July, the majority of England exceeded 30 °C (86 °F) and the majority of the Southeast and Midlands exceeding 32 °C (90 °F). Temperatures in London reached as high as 37.8 °C (100.0 °F) at Heathrow Airport.[13]

Temperaturess in the United Kingdom have cooled down considerably during the start of August. On 6 August, temperatures began to rise again, with 30.1 °C (86.2 °F) being recorded in Wisley. On 7 August, the majority of South East England is forecasted to exceed over 32 °C (90 °F) and up to 37 °C (99 °F) in London.


https://edition.cnn.com/2020/08/06/weat ... index.html

CNN)Western Europe is bracing for a sweltering heat wave as extreme temperatures are expected to grip the region for the second weekend in a row.
England will come close to its hottest temperature of the year Friday, set during last week's intense hot spell. Highs will also come close to the country's all-time heat record of 38.7 degrees Celsius (101.6 degrees Fahrenheit) set just last July, according to the UK Met Office, England's weather service.
The Met Office has already issued heat alerts for parts of England as temperatures this weekend are forecast to climb to near 37 Celsius (99 Fahrenheit).
However, this time heat wave conditions are expected to persist for at least seven days in London and some surrounding areas.


Last year were really hot: look at the 40 degrees and plus area,
