Sick of bumpy, delayed flights? New tech could help.

- By Julie Weed

It may be a tough summer to fly. More passengers than ever will be taking to the skies, according to the Transporta­tion Security Administra­tion. And the weather so far this year hasn’t exactly been cooperatin­g.

A blizzard warning in San Diego, sudden turbulence that injured 36 people on a Hawaiian Airlines flight bound for Honolulu, a 25- inch deluge of rain that swamped an airport in Fort Lauderdale, Fla.: The skies have been confoundin­g forecaster­s and frustratin­g travelers.

And it may only get worse as the climate continues to change. “Intense events are happening more often and outside their seasonal norms,” said Sheri Bachstein, chief executive of the Weather Co., part of IBM, which makes weather- forecastin­g technology.

So, will flights just get bumpier and delays even more common? Not necessaril­y. New sensors, satellites and data modeling powered by artificial intelligen­ce are giving travelers a fighting chance against more erratic weather.

Better data, smarter software

The travel industr y “cares about getting their weather prediction­s right because weather affects everything,” said Amy McGovern, director of the National Science Foundation’s AI Institute for Research on Trustworth­y AI in Weather, Climate and Coastal Oceanograp­hy at the University of Oklahoma.

Those better weather prediction­s rely on a type of artificial intelligen­ce called machine learning, where in essence a computer program is able to use data to improve itself. Companies create software that uses historical and current weather data to make prediction­s. The algorithm then compares its prediction­s with outcomes and adjusts its calculatio­ns from there. By doing this over and over, the software makes more accurate forecasts.

The amount of data fed into these types of software is enormous. IBM’S modeling system, for example, integrates informatio­n from 100 other models. To that, it adds wind, temperatur­e and humidity data from more than 250,000 weather stations on commercial buildings, cellphone towers and private homes around the globe. In addition, it incorporat­es satellite and radar reports from sources like the National Weather Service, the National Oceanic and Atmospheri­c Administra­tion and the Federal Aviation Administra­tion. Some of the world’s most powerful computers then process all this informatio­n.

Safer, calmer flights

Pilots have long radioed their encounters with turbulence to air traffic controller­s, giving aircraft coming in behind them a chance to illuminate the seat belt sign in time for the rough air. Now, a new fleet of satellites could help warn them earlier.

Tomorrow. io, a weather intelligen­ce company based in Boston, received a $ 19 million grant from the U. S. Air Force to launch more than 20 weather satellites, beginning with two by the end of this year and scheduled for completion in 2025. The constellat­ion of satellites will provide meteorolog­ical reporting over the whole globe, covering some areas that are not currently monitored. The system will report conditions every hour, a vast improvemen­t over the data that is currently available, according to the company.

The new weather informatio­n will be used well beyond the travel industry. For their part, though, pilots will have more complete informatio­n in the cockpit, said Dan Slagen, the company’s chief marketing officer.

The turbulence that caused dozens of injuries aboard the Hawaiian Airlines f light last December came from “an evolving thundersto­rm that didn’t get reported quickly enough,” Mcgovern said. That’s the kind of situation that can be seen developing and then avoided when reports come in more frequently, she explained.

Fewer snarls on the ground

The FAA estimates that about three- quarters of all flight delays are weatherrel­ated. Heavy precipitat­ion, high winds, low visibility and lightning can all cause a tangle on the tarmac, so airports are finding better ways to track them.

Weatherste­m, based in Florida, reports weather data and analyzes it using artificial intelligen­ce to make recommenda­tions. It also installs small hyperlocal weather stations, which sell for about $ 20,000, a fifth of the price of oldergener­ation systems, said Ed Mansouri, the company’s chief executive.

While airports have always received detailed weather informat ion, Weatherste­m is among a small set of companies that use artificial intelligen­ce to take that data and turn it into advice. It analyzes reports, for example, from a global lightning monitoring network that shows moment- bymoment electromag­netic activity to provide guidance on when planes should avoid landing and taking off, and when ground crews should seek shelter.

The software can help reduce unnecessar­y airport closures because its analysis of the lightning’s path is more precise than what airports have had in the past.

The company’s weather stations may include miniDopple­r radar systems, which show precipitat­ion and its movement in greater detail than in standard systems; solar- powered devices that monitor factors like wind speed and direction; and digital video cameras. Tampa Internatio­nal,

Fort Lauderdale- Hollywood Internatio­nal and Orlando Internatio­nal airports, in Florida, are all using the new mini- weather stations.

The lower price will put the equipment within reach of smaller airports and allow them to improve operations during storms, Mansouri said, and larger airports might install more than one mini- station. Because airports are often spread out over large areas, conditions, especially wind, can vary, he said, making the devices valuable tools.

More precise data and more advanced analysis are helping airlines fly better in cold weather, too. Deicing a plane is expensive, polluting and time- consuming, so when weather changes mean it has to be done twice, that has an impact on the bottom line, the environmen­t and on- time departures.

Working with airlines like Jetblue, Tomorrow. io analyzes weather data to help ground crews use the most efficient chemical de- icing sprays. The system can, for example, help crews decide if a thicker chemical treatment called anti- icing is needed and to determine the best time to apply the sprays to limit pollution and cost.
