Twisters asks if you can ‘tame’ a tornado. We have the answer

As successful nan erstwhile film, Twisters’ protagonists want to thief group affected by these highly destructive forces of nature. In nan 1996 movie, Jo Harding, played by Helen Hunt, aimed to cod capable information to create an precocious informing system. In Twisters, nan technological stakes person escalated. Kate has a mentation connected really to destabilize aliases “tame” a tornado. But is specified a point possible?

Science News went to nan movies pinch Maria Molina, a meteorologist astatine nan University of Maryland successful College Park, to find retired really overmuch of Twisters is grounded successful reality and really overmuch is getting swept up successful stormy storytelling. We besides said pinch Kevin Kelleher, retired head of nan Global Systems Laboratory astatine nan U.S. National Oceanic and Atmospheric Administration’s Earth System Research Laboratories. He worked arsenic nan method advisor connected 1996’s Twister and spent much than 2 years arsenic nan tornado advisor for Twisters.

Ultimately, Twisters is simply a movie, truthful nary 1 tin realistically participate nan theatre reasoning that this will beryllium a perfect, scientifically meticulous portrayal of upwind phenomena that, successful reality, we cognize truthful small about.

“Even aft 30 years from nan first movie to now, we really don’t cognize precisely really tornadoes form,” Kelleher says. “We cognize really nan rotation starts successful mid- and upper-level sections of nan large wind and useful its measurement down to nan surface. But we cognize now that that’s not nan full story.”

Molina still calls nan movie fun, and she chuckled knowingly astatine immoderate of nan technological elements she recognized on nan way. “They did effort to make rather a fewer things accurate,” she says.

OK, truthful is it really imaginable to destabilize a tornado?

When we first meet Kate, she and her investigation squad effort to tame a tornado by releasing a polyacrylate chemic into nan tornado’s funnel. According to Kate’s theory, nan chemical, a type of polymer, would sorb nan moisture successful nan aerial that serves arsenic substance for nan tornado, causing it to dice down.

“I deliberation that was thing that maybe, to me, was benignant of making maine cringe,” Molina says.

Kelleher admits that this is nan astir fantastical crippled constituent of nan movie. However, he explains that location is simply a ground to nan idea. Certain polyacrylates are superabsorbent polymers that tin clasp up to 1,000 times their weight successful water. In theory, if you injected capable of nan polymer into nan tornado’s funnel, it would sorb moisture and nan h2o would past autumn to nan ground, frankincense having immoderate power connected nan storm.

“Of course, it’s a matter of scale,” he says. “You can’t hardly ideate getting capable of this chemic successful nan large wind to make a difference.”

Naturally, a modified type of Kate’s research useful successful nan 3rd enactment to prevention nan day, but nan Twisters characters admit that their investigation still has a agelong measurement to go. Javi tells Kate that group whitethorn uncertainty her occurrence and declare nan tornado died connected its ain aliases tapered retired owed to a different utmost upwind event.

“Scientifically, that’s what I would say, right?” Molina says. “I’d say, ‘You don’t person a power tornado to guarantee that we understand each azygous spot of nan dynamics successful it.’”

The movie scientists usage radar to make 3-D models of tornadoes. Is that realistic?

For astir of nan film, Javi and nan squad usage phased array radars, aliases PARs, to seizure scans of nan tornadoes (SN: 9/4/23). They triangulate 3 PARs astir each tornado to create a 3-D exemplary truthful they tin amended understand really tornadoes form, which successful move leads to a amended expertise to foretell large wind statement and dissipation.

According to Molina, this was spot on.

“That was really cool,” Molina says. “So from NOAA’s National Severe Storms Laboratory, they person section crews that spell retired and get scans utilizing [this] radar … [and] erstwhile they’re trying to seizure a supercell successful nan field, they do deploy 3 astir it to get that afloat perspective.”

Twisters evidently plays up nan existent consequence factor, according to Kelleher. In nan movie, Javi’s squad of researchers brings nan radars “exceptionally adjacent to nan storm,” placing them connected nan crushed to get meticulous data. In reality, astir of these section radars would beryllium overmuch larger than really they are portrayed successful nan movie, allowing them to beryllium farther distant from nan storm, and would stay attached to nan trucks.

What’s nan woody pinch nan occurrence tornado seen successful nan trailer? Could that really happen?

A fire tornado, aliases “firenado,” is featured concisely successful nan film, and dissimilar nan infamous “sharknado” of TV-movie fame, it “really is not a stretch,” Kelleher says (SN: 9/9/18)

“I really liked that they put that successful there,” Molina says. “In California, there’s been rather a fewer fires complete nan past respective years. And location were reports of a firenado occurring arsenic a consequence of nan heat.”

Kelleher besides says that wildfires tin shape their ain thunderstorms that whitethorn person nan characteristics of supercell thunderstorms. Such storms person a strong, persistent updraft called a mesocyclone that tin lead to tornadoes.

How does this movie grip nan rumor of ambiance change?

Despite being astir utmost upwind phenomena, Twisters ne'er mentions nan building “climate change.” Kelleher explains that nan workplace wanted to sensitize folks to nan risks “without being preachy.”

Also, researchers don’t rather cognize what to expect regarding tornadoes and ambiance change. According to Molina, it’s unclear if location will beryllium much tornadoes successful nan early owed to changing ambiance conditions. The rumor continually circles backmost to a deficiency of data.

Still, decades’ worthy of changing trends successful tornado behavior connection immoderate clues (SN: 10/18/18).

“The trends are that nan accepted Tornado Alley is expanding,” Kelleher says. “It’s not really leaving nan accepted Tornado Alley, but it is expanding eastward into, you know, Arkansas, Mississippi, Alabama. And those tornadoes are looking and getting bigger.”

How do scientists consciousness astir self-taught large wind chasers?

Unlike its 1996 predecessor, Twisters shows large wind chasing from 2 very different perspectives: the professionally trained investigation scientists and nan self-taught enthusiasts successful nan field.

“With our phones, now everybody has fresh entree to radar information and astir of nan information that nan meteorologists have, and truthful tornado chasing has go a immense thing,” Kelleher says.

Molina enjoyed seeing really galore enthusiasts location were astatine nan state stations and hotels nan protagonists visited and says that is beautiful meticulous to what nan section looks for illustration now.

“If personification is retired chasing for nosy and conscionable because of their ain curiosity, that’s, you know, bully for them,” Molina says. “They’re capturing video. We tin usage that video. We’ve learned a batch astir tornadoes done video.”

Too galore chasers successful nan field, however, tin origin issues. A communal title from researchers that Molina and Kelleher some constituent retired is congested roads aliases postulation jams that tin forestall scientists from mounting up their section instrumentality aliases arriving connected nan segment connected time. Molina mentions really this tin sometimes lead to immoderate of nan unsafe driving Twisters portrayed betwixt nan 2 main chaser groups arsenic they compete to spot who arrived first astatine a storm.

Kelleher besides points retired that nan movie depicts nan actions of group who, he believes, get excessively adjacent to nan storms and put themselves astatine risk.

“These are exceptionally vulnerable forces of quality you don’t want to messiness pinch astatine all,” Kelleher says. “So do not effort to deliberation you tin thrust into a tornado and past it. It’s conscionable not doable.”
