Phys.org  May 25, 2022 Researchers from the Southern Methodist University will discuss a method for using infrasound pulses from detonated munitions to probe atmospheric phenomena at the 182nd Meeting of the Acoustical Society of America meeting. The sound they record propagates upward into the atmosphere and is refracted back down to the ground. The information they provide on the upper atmosphere can tell us about the winds aloft, and these can affect the weather at the ground. However, it requires sizeable source to have enough strength to reach the atmosphere and bounce back. Therefore, they set up detectors in the […]
