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” […]
