Scientists Convert Drones Into Tornado-Predicting Machines

The storm chasers of the future are lifting off today. Researchers at Oklahoma State University are developing a fleet of data-collecting drones that may help forecasters—and residents of tornado-prone regions—get ahead of dangerous weather events.

Not all storms are the same when it comes to predictability. Hurricanes and blizzards are pretty easy to spot. Meteorologists can typically call them days ahead of time. But tornadoes are wild, and they can whip up suddenly. Right now, our instruments can only spot a tornado 10 to 15 minutes before it happens. That’s simply not enough time for those in danger to get out of the way.

And while weather balloons are useful, their success depends on being in the right place at the right time. "Once dropped, they can’t move and thus are subject to the unpredictable nature of a storm," mechanical engineer Jamey Jacob told Popular Science. The ideal monitoring vehicle will be steerable, durable, and loaded with sensors.

Enter the drones.

Jacob and his colleagues hope to integrate the drones into normal forecasting instrument arrays within the next four years.

"Eventually what we want is to get to a point where you're watching the weather channel," says Jacob, "and they're reporting data that they're getting from the drones, and nobody cares—it's just the data that's coming in."

Once everything is up and running, Jacob told PBS NewsHour, the drones will ideally be able to extend storm warnings from 10 or 15 minutes to as much as an hour—which could give local residents enough time to prepare, batten down the hatches, or evacuate. “And you know that’s really going to save lives in the end.”

It Just Snowed In the Sahara for the Second Time In Less Than a Month

The town of Aïn Séfra, Algeria might need to find a new nickname. Though it’s often referred to as “The Gateway to the Sahara,” the 137-year-old province in northwest Algeria is currently digging out from a rare—and unexpected—snowstorm that left the desert town covered in several inches of snow and battling sub-zero temperatures.

While the Daily Mail reported that “locals took to the nearby sand dunes to enjoy the unusual weather,” the strangest part of the story is that this is Aïn Séfra’s second snowfall in less than a month. On Sunday, January 7, a freak blizzard left parts of the Sahara blanketed in as much as 16 inches of snow.

This most recent storm marked the region’s fourth snowfall in nearly 40 years; in addition to January's dose of the white stuff, the area has been hit with other surprise wintry events in February 1979 and December 2016.

But North Africa isn’t the only area that’s seeing record-breaking weather events. On Saturday, February 3, 17 inches of snow fell on Moscow within 24 hours in what the country has dubbed “the snowfall of the century.” In mid-January, Oymyakon, Russia—a rural village in the Yakutia region, which is already well known as one of the coldest inhabited areas of the world—saw temperatures drop to -88.6°F, making it chilly enough to both bust thermometers and freeze people’s eyelashes. And you thought dealing with single-digit temperatures was tough!

Record-Breaking 17 Inches of Snow Covers Moscow in 24 Hours

Moscow sees some of the most brutal winters of any world capital, but even locals weren't prepared for the most recent winter storm to batter the city. As Newsweek reports, a record-breaking 17 inches of snow buried Moscow within 24 hours.

Roughly 7 inches of snow fell just on Saturday, February 3, and the deluge continued through the following Sunday. The accumulation has already been dubbed the "snowfall of the century," and officials expect up to 3 additional inches to cover the ground over the next three days.

The sudden blizzard has brought life to a stand-still in the metropolis of 12 million. The mayor is warning motorists to stay off the roads as around 15,000 snowplows clear the snow. About 2000 trees have been toppled by the storm, injuring at least five people and killing one.

Even as the worst of the weather winds down, over 40,000 people in Moscow and the surrounding regions are without power. Meanwhile, traveling in and out of the city has become close to impossible: Around 100 flights are grounded at the local airport indefinitely and at least 10 have been canceled all together.

The historic snowfall hasn't stopped many of Moscow's tougher residents from venturing outside. Check out photos from the event below.
