NASA: Hurricane Helene produced 'enormous' gravity waves in upper atmosphere

Nov. 8 (UPI) -- A new technology developed by NASA to predict space weather showed that Hurricane Helene produced "enormous" waves in the Earth's upper atmosphere as it came ashore on Sept. 26, the agency says.

NASA's Atmospheric Waves Experiment, or AWE, was launched in November 2023 and mounted on the outside of the International Space Station. Its mission is to scan for atmospheric gravity waves, described as ripple-like patterns in the air generated by atmospheric disturbances such as violent thunderstorms, tornadoes, tsunamis, wind bursts over mountain ranges, and hurricanes.
