Now, AI can predict where and when lightning will strike

Washington D.C. [USA]

Since lightning is considered one of the most unpredictable natural occurrences of nature, researchers found a method of predicting when lightning may strike.

At EPFL’s School of Engineering, researchers in the Electromagnetic Compatibility Laboratory, led by Farhad Rachidi, have developed a simple and inexpensive system that can predict when lightning will strike to the nearest 10 to 30 minutes, within a 30-kilometre radius. The system uses a combination of standard meteorological data and artificial intelligence.

The research paper published in — Climate and Atmospheric Science — a Nature partner journal. The researchers are now planning to use their technology in the European Laser Lightning Rod project.

“Current systems are slow and very complex, and they require expensive external data acquired by radar or satellite,” explained Amirhossein Mostajabi, the PhD student who came up with the technique.

“Our method uses data that can be obtained from any weather station. That means we can cover remote regions that are out of radar and satellite range and where communication networks are unavailable,” added Mostajabi.

What’s more, because the data can be acquired easily and in real-time, predictions can be made very quickly — and alerts can be issued even before a storm has formed.

The EPFL researchers’ method uses a machine-learning algorithm that has been trained to recognise conditions that lead to lightning.

To carry out the training, the researchers used data collected over a ten-year period from 12 Swiss weather stations, located in both urban and mountainous areas.

Four parameters were taken into account: atmospheric pressure, air temperature, relative humidity, and wind speed. Those parameters were correlated with recordings from lightning detection and location systems.

Using that method, the algorithm was able to learn the conditions under which lightning occurs. Once trained, the system made predictions that proved correct almost 80% of the time.

This is the first time that a system based on simple meteorological data has been able to predict lightning strikes through real-time calculations. The method offers a simple way of predicting a complex phenomenon.

Streep, Miranda and Stone are named as Met Gala co-0chairs

Dec 8, 2019

NEW YORK — Next year's Met Gala may be the closest we'll ever come to getting a Miranda Priestly moment at the starry event. Meryl Streep has been named as a co-chair of the Metropolitan Museum of Art's Costume Institute. The Oscar-winner played Priestly, a thinly veiled fictional version of Vogue editor Anna Wintour, in the movie "The Devil Wears Prada." Wintour clearly has no hard feelings because she selected Streep as a co-chair along with Lin-Manuel Miranda and fellow Oscar-winner Emma Stone. Designer Nicolas Ghesquiere rounds out the group. The gala's theme is "About Time: Fashion and Duration," which...

ABC says interview with Epstein accuser wasn't ready to air

Dec 8, 2019

NEW YORK — ABC News faced questions Tuesday about its reluctance to air a sensitive story of alleged sexual misconduct after a leaked video emerged of reporter Amy Robach complaining about how her bosses handled an interview with a Jeffrey Epstein accuser. The conservative web site Project Veritas released video of Robach venting that "every day I get more and more pissed" that her 2015 interview with Virginia Giuffre never made the air. Robach made her remarks late in August while sitting in a Times Square studio with a microphone but not on the air. ABC said Tuesday that the...

Olivia Newton-John's final 'Grease' ensemble fetches $405K

Dec 8, 2019

BEVERLY HILLS, Calif. — Two collectors said you're the one that I want to Olivia Newton-John's iconic "Grease" leather jacket and skintight pants at an auction Saturday in Beverly Hills. Julien's Auctions says the combined ensemble, which Newton-John's character Sandy wears in the closing number of the 1978 film, fetched $405,700 total. The leather jacket sold for $243,200 and the pants, which Newton-John famously had to be sewn into, went for $162,500. Other "Grease" memorabilia included a Pink Ladies jacket that went for $50,000 and a poster signed by Newton-John, John Travolta, director Randal Kleiser and producer and songwriter John...

Scorsese, De Niro and Pacino on time and 'The Irishman'

Dec 8, 2019

NEW YORK — They come into the room not like the moveable Mount Rushmore that they are but like three old friends, energized by being in each other's company. They are chatting about movies. Martin Scorsese comes first, then Al Pacino, then Robert De Niro. They're trailed by a small army of publicists and assistants that quickly recedes out of the room. Constant through the momentary commotion is Scorsese enthusiastically remembering Michael Powell and Emeric Pressburger's "A Matter of Life and Death," and quoting its lines to a rapt Pacino. Their movie, "The Irishman," also deals majestically with matters of...

After son's death, Craig Morgan finds God's purpose in song

Dec 8, 2019

NASHVILLE, Tenn. — The last evening that country singer Craig Morgan spent with his 19-year-old son, Jerry, was during one of Morgan's performances at Grand Ole Opry three years ago. "The last pictures I have of us together is on that stage," Morgan, 55, said backstage at the Opry House this week. "So this is a very special place. It was anyway before, but now it has additional meaning, knowing this is where we hung out together." His son, Jerry, who was home visiting from college, died in a drowning accident on Kentucky Lake in July 2016. Three years later,...
