Phys.org October 10, 2024 Convectively coupled equatorial waves (CCEWs) can be potential sources of predictability for sub-seasonal to seasonal prediction over northern Australia. Researchers in Australia studied the relationship between these waves and rainfall in northern Australia from 1981 to 2018. They found the waves had a significant impact on rainfall during the southern summer (December–February) and autumn (March–May). When waves combined in certain ways, heavy rain events become even more likely. Due to Australia’s vast landmass and local geography, the impacts of these waves were quite different across the continent. They showed that the activity of the “atmospheric melodies” […]

Explosions help probe elusive atmospheric waves
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 […]
