00:00Hurricane Helene was a devastating storm, ripping through Florida and the east coast
00:08of the United States.
00:10Experts estimate the damages related to the tempest will add up to a staggering $30-47
00:15billion, with more than 230 people killed as a result of the Category 4 storm.
00:21However, NASA is now reporting that it also created waves elsewhere, namely in the upper
00:25atmosphere around our planet.
00:27According to readings from NASA's Atmospheric Waves Experiment, or AWE, an instrument mounted
00:32on the International Space Station which detects faint light released by mesospheric gas called
00:36airglow, 56 miles above our planet's surface they detected ripples in that light, revealing
00:41just how much terrestrial weather may impact space weather.
00:45These ripples reveal the movement of atmospheric gravity waves caused by oscillations below
00:49them.
00:50NASA says it's similar to what happens when you drop something into water, with ripples
00:53cascading from the central point of impact.
00:55The atmospheric ripples, however, are caused when air is forced upwards by topographical
01:00changes like mountains and hills.
01:02That air then drops down again due to gravity, where it then oscillates and creates these
01:06ripples.
