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