The barriers - 300m (980ft) high and up to 100 miles long - would act like hill ranges, softening winds before twisters can form.

They would cost $16bn (£9.6bn) to build but save billions of dollars of damage each year, said Prof Rongjia Tao, of Temple University, Philadelphia.

He unveiled his idea at the American Physical Society meeting in Denver.
However critics say the idea is unworkable, and would create more problems than it solves.
Threat over 'forever'
 
Every year hundreds of twisters tear through communities in the great north-south corridor between the Rocky and Appalachian Mountain ranges.

Instead, they would soften the clashing streams of hot southern and cold northern air, which form twisters in the first place, Prof Tao said.

"If we build three east-west great walls, one in North Dakota, one along the border between Kansas and Oklahoma, and the third in the south in Texas and Louisiana, we will diminish the threats in Tornado Alley forever," he said.

As evidence, he points to China - where only three tornadoes were recorded last year, compared to 803 in the US.

China too has flat plain valleys running north-south, but the difference is they are broken up by east-west hill ranges.

Although only a few hundred metres high, they are enough to take the sting out of air currents before they clash, Prof Tao believes.

Hotspot Back in the US, he notes that the flat farmlands of Illinois experience wildly varying risks of twisters.
"Washington County is a tornado hotspot. But just 60 miles (100km) away is Gallatin County, where there is almost no risk," he told BBC News.

"Why? Just look at the map - at Gallatin you have the Shawnee Hills."
These act like a barrier 200-250m (820ft) high, protecting Gallatin, he says.
"We may not have east-west mountain ranges - like the Alps in Europe - we can build walls."

"We've already been doing computer simulations and next we aim to build physical models for testing [in wind tunnels]."
Rather than create an eyesore, the walls could be "attractively" designed, says Prof Tao.
He cites the Comcast skyscraper in Philadelphia - also about 300m high, and built with a reinforced glass exterior.
"Our tornado wall could even be built of glass too. It could be a beautiful landmark," he told BBC News.
"I spoke to some architects and they said it's possible. It would take a few years to finish the walls but we could build them in stages."
Prof Tao has yet to approach government or environmental agencies with his scheme, but the reaction from meteorologists has been highly sceptical.
Harold Brooks, of the National Severe Storms Laboratory, said the great walls "simply wouldn't work".

Mark Zuckerberg's firm is planning to buy the company for around £11bn.

Opponents want US regulators to stop the deal until Facebook provides more information on what it plans to do with the personal data of WhatsApp's users.

But Facebook said it will operate as a separate company and honour existing privacy arrangements, which include not collecting user data for advertising.

"WhatsApp built a user-base based on its commitment not to collect user data for advertising revenue," read a complaint filed with the US Federal Trade Commission (FTC). It was drawn up by two non-profit groups, the Electronic Privacy Information Center and the Center for Digital Democracy.

They added: "Users provided detailed personal information to the company including private text to close friends. Facebook routinely makes use of user information for advertising purposes and has made clear that it intends to incorporate the data of WhatsApp users into the user profiling business model.

"The proposed acquisition will therefore violate WhatsApp users' understanding of their exposure to online advertising and constitutes an unfair and deceptive trade practice, subject to investigation by the Federal Trade Commission."

And the groups, which work on research and consumer protection online, asked the regulators to investigate the deal "specifically with regard to the ability of Facebook to access WhatsApp's store of user mobile phone numbers and metadata".
'Insulate'
 
Facebook, the world's top social network with 1.2 billion users, generates the majority of its revenue by showing ads that target users by age, gender and other traits.

"As we have said repeatedly, WhatsApp will operate as a separate company and will honour its commitments to privacy and security," Facebook said in a statement seen by Reuters.
 
Facebook announced its intention to buy WhatsApp, which has 450 million users who are able to send instant messages and other media over mobile, with cash and stock.

There is no charge for individual messages, which are sent using wi-fi or data connections, making it cheaper than SMS messaging in many cases. Other users pay around £0.60 per year subscription.
Referring to the business model, Jan Koum wrote on the WhatsApp website: "When people ask us why we charge for WhatsApp, we say, 'Have you considered the alternative?'"

Despite assurances by WhatsApp and Facebook that the privacy policies will not change, the groups noted that Mark Zuckerberg's social networking company has in the past amended an acquired-company's privacy policies.

Notably, it did so with the Instagram photo-sharing service that it bought in 2012.
Regulators must require that Facebook "insulate" WhatsApp user information from access by Facebook's data collection practices, read the complaint, which was dated 6 March 2014.

"WhatsApp users could not reasonably have anticipated that by selecting a pro-privacy messaging service, they would subject their data to Facebook's data collection practices," read the filing.

The FTC will decide whether the acquisition can go ahead and, if so, whether or not conditions should be imposed.
