The recent havoc wreaked by tornadoes in Oklahoma shows again just how destructive and terrorizing these storms can be and how better predictive technology is needed. Oklahoma State University students working to solve this problem have developed the ultimate storm chaser -- a drone that can fly into the storms and send data back to meteorologists.
Jamey Jacob, a professor of mechanical and aerospace engineering at OSU, told us that the unmanned aerial vehicle (UAV) can penetrate severe thunderstorms, including the supercells from which tornadoes can develop. Once inside the storm, "the vehicles measure parameters pertinent to meteorologists, namely pressure, temperature, humidity, and wind speed, that can be useful for predicting storm development and formation."
Jacob's students developed the tornado-exploring UAV as part of a class project to tackle real-world design problems, but he actually began working on the technology as an undergraduate back in the 1980s. OSU student engineers have been working on UAV technology for more than a decade but only recently started work again on vehicle designs for weather prediction and exploration, he said.
The UAV was developed using a number of materials, including composites like carbon fiber, fiberglass, and Kevlar, to make it durable enough to withstand flights into supercells. It is not designed to fly directly into a tornado itself, but it measures the conditions from which a tornado will form.
These type of drones -- Jacob and his team are working on a number of concepts and prototypes -- could be used to improve predictions for tornadoes, giving people more warning and a better chance at protecting themselves. "The vehicles will gather data that can be used to improve numerical weather models and hence forecasting. Ideally, improvements in these models would allow warning to increase substantially over where it is currently."
Jacob and his team are working on a number of other UAVs, including Talos, a vehicle that was developed in collaboration with the Department of Homeland Security for a different application but could be adapted for storm forecasting. Its recently completed test flight is shown in the video below. He said he and his team are working with partners at other universities to secure development funding to continue their work, and they are seeking permission from the Federal Aviation Administration to fly their drones.
