Drones could revolutionize future weather forecasts and accuracy

Posted: Updated:
Amazon may have the wrong use for the robotic remote controlled vehicles, commonly called drones, but they have the right idea. Research facilities at multiple agencies and Universities are testing how drones can collect meteorological data around the world that would ultimately help in forecasting. More importantly, they could sample the atmosphere in hard to reach, remote locations where weather data is impossible to get. The seemingly never ending Atlantic and Pacific Oceans would be a great place to start.


The NASA Global Hawk Unmanned Aircraft System (UAS)


The computer forecasting models get all of their data from surface locations worldwide, as well as with weather balloon launches at strategic locations. But we are unable to sample much of the atmosphere because 70% of the globe is covered by water, where no people or structures can survive. So collecting viable data to use in these forecasting models has essentially been holding us back from fine tuning an ever changing forecast for the last half century. But these drones might be able to provide additional data, especially in key situations like potential land falling hurricanes, or the “polar vortexes” that make their way toward the U.S.

So last summer, NASA flew the Global Hawk drone into Tropical Storm Nadine in the east Atlantic. The maximum flight duration of the current piloted aircraft known as the “Hurricane Hunter” is insufficient to cross the Atlantic and back, while also spending several hours sampling the environment around the storm. But the Global Hawk can fly at altitudes above 50,000 feet and stay airborne for over 30 hours. That makes these drones ideal for investigating these natural phenomenon AND does it without putting the pilots and staff on board a plane in harm’s way.

These aren’t the only ways drones are being tested against Mother Nature. The Los Angeles Times reports that Oklahoma State researchers are developing a drone capable of withstanding the high winds from tornadoes, with several test flights already conducted.

The University of Virginia is involved as well conducting tests to develop a drone that will supplement those weather balloon launches I mentioned above, aiding them in collecting atmospheric soundings at low levels of the atmosphere.

Ultimately, it will likely be the cost of these unmanned vehicles that will hold current research and roll out back for a while. Current estimates show that each one, depending on its use and capabilities, could cost more than a quarter million dollars. Might be a small price to pay for further understanding of our atmosphere and ultimately saving lives. There are currently no estimates on when these drones could hit the market.

    There's a big misconception about food vendors at the Minnesota State Fair. Many people think you can set up a booth, work 12 days and make a pile of cash. But it's not that easy. Aside from a lot of hard work, it also takes some luck.

    The Minnesota State Fair is adding 28 new foods to the already massive, artery-clogging list of 500 foods from 300 different vendors. New food include everything from a bacon-wrapped turkey leg and beer gelato to a shrimp dog and chocolate salami.

    Snowy owl that survived Washington, DC bus hit dies in Minnesota

    The snowy owl that underwent surgery and rehab at the University of Minnesota's Raptor Center after being struck by a bus in Washington, D.C. has died. The owl was returned to the wild in April, but was recently found dead on the side of a Minnesota highway.
