The models need further refinement, however, the researchers noted.
"There is much more work that needs to be done before infrasound measurements can be used as a forecasting tool," Cheung told OurAmazingPlanet. The atmosphere is a difficult environment to model how sound travels due to rapidly changing conditions there, which affect the density of air and thus the speed of sound through it. These new findings "represent a first step of this long process," Cheung said.
Stopa, Cheung and their colleagues Milton Garcés and Nickles Badger detailed their findings in the December issue of the Journal of Geophysical Research-Oceans.
