Australia's climate is influenced by oceanic and atmospheric patterns, known as climate drivers. The El Niño–Southern Oscillation (ENSO) is a key driver, with phases including La Niña, Neutral, and El Niño. These phases affect global and Australian climates, causing floods, droughts, and temperature changes. La Niña strengthens trade winds, leading to more rain and cyclones in Australia, while El Niño weakens them, increasing drought risk. Understanding ENSO helps predict climate impacts, with updates provided by the Bureau.
