Lightning around the world

After the burst of #vent at 120 km / h at Metz-Nancy-Lorraine airport (57) the #orage continued on its way north of the department to the German border with a gust of 126km / h Seingbouse (57)! Possible damage under this cell

Under the #orages very violent over Lorraine this evening, a powerful gust of 126 km / h was measured at Seingbouse in Moselle, accompanied by a drop in temperature of 9 ° C in the space of 18 minutes from 21 ° C to 12.5 ° C !

Nearly 8,500 lightning bolts on #PACA this Tuesday, including 2,600 in the #Var and 2300 in the Alpes-de-Haute-Provence. Locally heavy rains with in particular 80 mm on the solid mass of Sainte-Victoire and 40 mm in the west of the Moors.

New Delhi, July 17, 2021
The number and frequency of lightning strikes is increasing globally. The proverbial bolts from the blue are killing more people every subsequent year. Between April 2020 and March 2021, 18.5 million lightning strikes were recorded in India. This was a 34 per cent increase from the 13.8 million strikes between April 2019 and March 2020.

These statistics were shared at a webinar on lightning strikes here today, organised by Centre for Science and Environment (CSE) and Down To Earth magazine. The webinar attempted to understand why lightning strikes were increasing in numbers, and their connection to climate change and growing urbanisation.

Some of the states that have been at the receiving end of these strikes are Punjab, Bihar, Uttar Pradesh, Jharkhand, Madhya Pradesh, Haryana, Puducherry, Himachal Pradesh and West Bengal. In Punjab, the increase in number of lightning strikes has been a staggering 331 per cent annually, while in Bihar — where 401 people lost their lives to lightning strikes during the year — there was a 168 per cent rise. Overall, 1,697 people were struck down dead by lightning in India between March 2020 and April 2021.

“There is growing scientific evidence that climate change may be sparking more lightning across the world. Rapid urbanisation and population growth have guaranteed an intensification of human exposure to lightning hazard,” says Down To Earth managing editor Richard Mahapatra.

The evidence

Enough global studies are now emerging about this phenomenon. A 2015 California University study has projected that an increase in average global temperatures by 1ºC would increase the frequency of lightning by 12 per cent.

Another paper, soon to be published in the journal Atmospheric Chemistry and Physics, warns that the frequency and intensity of lightning strikes in India are expected to increase by 10-25 per cent and 15-50 per cent respectively by the end of the century.

A foreboding dimension of the surge in lightning strike numbers is their link to forest fires. “Scientists from the Hemvati Nandan Bahuguna Garhwal University in Srinagar, and the Indian Institute of Technology, Kanpur, have studied the concentration of cloud condensation nuclei (CCN) in different weather conditions in the central Himalayan region. They have found a five-time higher concentration of CCN in the atmosphere during forest fires as against during rains. In May 2021, researchers in Australia linked excess CCN to the increased number of lightning strikes during the 2019-20 Australia forest fires,” says Kiran Pandey, programme director of CSE’s environmental resources unit.

What can be done to prevent deaths?

Some progress has been made to counter the adverse effects of lightning strikes. The rise in fatalities has prompted the India Meteorological Department (IMD) to start lightning forecasts from April 1, 2019. Lightning India Resilient Campaign (LRIC), a joint initiative of several bodies such as Climate Resilient Observing-Systems Promotion Council (CROPC), National Disaster Management Authority, IMD, Union Ministry of Earth Sciences and others aims to reduce the number of deaths due to lightning strikes to less than 1,200 a year by 2022.

“The LRIC says its campaign has been successful in bringing down deaths by more than 60 per cent within two years. Dedicated efforts by governments of states like Andhra Pradesh and Odisha have led to a 70 per cent reduction in fatalities,” says Akshit Sangomla, senior reporter with Down To Earth.

“The lightning incidents recorded reveal that seasonality of lightning is different for different states. Therefore, it is important that the lightning risk management programme for each state is customised according to the seasonality, intensity and frequency of lightning. States should undertake lightning micro-zonation for the regions inside their boundaries, depending on their geography, to handle the disaster and death risks better. These are LRIC’s recommendations and they make a lot of sense,” says Pandey.

Says Mahapatra: “We may not be able to prevent every single lightning fatality, but we can definitely decrease their number substantially. The first step is to create general awareness about some universal safe practices, for example, to stay indoors for up to 30 minutes after the last flash if the time between a lightning flash and thunder is less than 30 seconds. The next steps would involve making use of the evolving science and technology on the subject and decentralising predictions and risk management.”

A look back at this weekend's thunderstorms up to 126km Article written on Monday 23 August 2021 by gregory

As announced by our services for several days, a fairly marked storm damage caused locally violent thunderstorms in the east of the country.
This Saturday at midday, violent thunderstorms affected eastern Burgundy with hailstones, 1 to 3cm in diameter, and strong electrical activity. It is especially on the department of Moselle that the storms were most virulent where strong thunderstorms swept the east of the metropolitan area of Metz with powerful gusts of wind. We measured a gust of 126km / h at Seingbouse, 120km / h at Metz-Nancy-Lorraine airport. This is an absolute monthly record for this position (the old one was 88km / h on August 24, 2015) and 92km / h in Nonsard (55).
The town of Saint Avold (Moselle), located east of Metz, has experiencedsignificant damage on the evening of Friday August 21 due to a supercell type storm accompanied by hail. Several roofs and trees were torn off. Some families had to be relocated. These thunderstorms evacuated to Germany overnight from Saturday to Sunday.

Lightning strikes on Saturday August 21, 2021
Heavy lightning strikes continue in the northern sky today. It looks like it was taken with a telephoto lens from my home in Hiratsuka at 19:30 on August 30, 2021. The clouds are always illuminated by Kaminari, just like Laputa.

It is the time lapse of yesterday's thunder. It was taken from my home in Hiratsuka from 19:41 to 49 on August 30, 2021. Each video of about 3 seconds is compared and brightly combined with one image, and it is played back at about 30 times speed. Cumulonimbus clouds are growing steadily while shooting thunder violently. The clouds illuminated by lightning shine in various colors, like illuminations.

Love at first sight #WhiteHouse I laughed about it but I was very scared. Fortunately, it was not live! #Reporting

THE STORMS RETURN AND WITH THEM THE "SPRITES", electrical discharges that occur over the troposphere at heights between 50 and 90 km. This spectacular one was captured this morning (30-Aug) at 03:21:22 TUC Marc Corretgé (
@marccg96) from Alpicat,#Lleida . The camera was operating at 25 fps

40,738 lightning struck the ground, 113,324 counting intraclouds in the geographic window shown.
Detail of the lightning registered in four areas affected by the strong storms.

Great electrical activity at the moment in Hellín, with a storm at the gates of the city. In the next few minutes it is not ruled out that it can download forcefully.#Albacete#meteoAB#DANA#tormentas

What a wonderful photo! One of the countless electric shocks we had last night in Hellín, on the Acecasa oil mill (

I don't know if this photo belongs to this thread.
It reminded me of this February 22, 2020 session where the crew talked about an open portal in the Middle East

: (L) Okay. Next topic. Oh, there was this weird video that Niall found. It was really weird.

Cosmic phenomenon? Strange waves pulse through cloud in skies over northwestern Syria --
Comment: We are most certainly not in Kansas anymore... Alien hunters and conspiracy theorists of all sorts do not need much to get them to seek traces of extraterrestrial guests or secret governmental programmes. A clip said to be filmed in...

(Niall) It's a video shown a couple of weeks ago supposedly somewhere south of Aleppo. That's near the big war zone in Idlib. It's looking up in the sky fixed on a cloud and there are like waves rippling up through the cloud.

A: We told you long ago that there is a large portal over the Middle East. This was a breaching of the realm curtain.

Q: (L) So... Was something coming in, or getting out of here?

A: Coming in!

Q: (Artemis) Something came in... Prepare for the worst!

(Chu) Something like what?

A: We told you that there would be strange cosmic phenomena!
Several people in Oaxaca, Mexico have shared images of a strange phenomenon in the sky, where they appreciated a red beam of light in the middle of the night.

The inhabitants of the Isthmus of that entity published several photographs through social networks, in which it is possible to see a beam of red light. This event generated concern among some citizens, as they thought it was a paranormal phenomenon.

NASA said it was a Sprite



19-year-old roofer struck and killed by lightning while working in Bradenton
Manatee County Fire Rescue responded shortly before 3 p.m. to 14816 Skip Jack Loop and pronounced the victim dead at the scene in a residential neighborhood.
“I just heard a huge explosion,” neighbor Neia Conceico said. “It wasn’t even raining.”
The Manatee County Sheriff’s office says the man was working as roofer, when he was struck. His identity has not yet been released.
After calling 911, Conceico says she saw the man lying on the roof. His co-workers were preforming CPR.
“It’s a lot to process … I just wish in that time, I could have done some miracle,” she says.
The Manatee County Sheriffs office will conduct a full investigation. The victim's identity has not yet been released.
The lightning bolt was captured on Klystron 9 radar.

This is the third lightning fatality this year in Florida and the tenth this year in the U.S.
Last year, 17 people across the country were killed by lightning.
Among lightning fatalities nationally, 44% are under the age of 20, and 89% are male.

Webcam image of the enormous lightning strike, yesterday in Enschede! Also notice the special "click" you hear immediately after impact (at 20:38.06). This is only observed if you are very close to an impact, often less than 300 meters.#onweer through @BernardPoel

Recording starts shortly after the lightning strike, the #Donner can still be heard well and the frightening birds can be seen #Köln#Gewitter

Almost 30,000 #éclairs recorded for this day of September 8 with 1/3 of these for the departments of #LotEtGaronne , of the'#Allier , of the #Dordogne as well as #HauteVienne . Complete data ->
Mysterious Lights appear in Shenyang, #China. An official said this is due to the density of the clouds and water vapor.

It seems that this one may have been due to the heavy rain, angle of the light, and the quality of the camera&video probably made it seem even more vivid. Sputnik reports on it here, and another tweet shows the building once the weather changes:

My first thought was, that this is a phenomena

which appears with digital cameras with CMOS sensors. CMOS sensors do not read out images all at once. Instead they do it more like an old TV; line by line (bunch of lines; the more at once / faster - the broader the brighter stripe). Think of the principle when scanning images on a scanner; the image is scanned line by line.

When a sudden very bright flash appears, as often observed with lightning, you get a stripe of overexposure in your frame - which makes it look like the image above. The stripy effect applies also to still images, when you use the digital shutter instead of the mechanical shutter. Digital Video cameras always use a digital shutter, hence the stripe effect and reading-out issue.

The effect will be over, the day the industry releases so called "global shutters" with CMOS sensor, which would be fast enough to read out video material image by image (all at one, so to speak), instead of line by line.

CCD sensors don't do that

Older CCD sensors were different, they read out the full image wholly, all at one - and that is the reason why older cameras do not have that ugly "stripy" effect when you make videos or still images of thunderstorms.

PS: That the Middle East camera shows the stripe effect vertically, I assume is because either the sensor was mounted that way, or the person held the camera vertically. (But this is my assumption)


Here I post two images where you can see the stripe effect. Notice that the effect is always a bit different: • dependent on shutter speed • internal read-out speed, • how bright the lightning is, • and what camera has been used. Sometimes, when only weak a lightning strike appears, you can get away without stripes (in still images). So, it is a pretty erratic effect. I also feel that every camera gives slightly bit different flavor. In my case the camera sensor / read out - bends the horizontal line ever so slightly.

I hope this helped to understand the possibility, that phenomenas we see (or being "illusterated" through other people's material, are not always necessarily of 'magic' origin.


For the technical: During this morning thunderstorm over Stockholm South on 29 June 2020, at 04:12 - an Olympus EM1X camera was used together with an extreme bright lens, a ED 17mm f 1.2 PRO and a shutter speed of 1/80 second. Together with a feature, which allows the camera to take 60 frames (still images) per second !
