Pacific Walker Circulation News Today

A University of Hawaiʻi at Mānoa assistant professor and an international team of researchers have revealed shifts in the tropical Pacific’s “Pacific Walker Circulation,” potentially leading to more prolonged El Niño and La Niña events, and intensifying climate-related impacts.

The Pacific Ocean covers 32% of Earth’s surface area, more than all the land combined. Unsurprisingly, its activity affects conditions around the globe.

We could see more multi-year El Niño and La Niña events in Australia, according to an international team of researchers including a scientist from The Australian National University (ANU). Dr Georgy Falster from ANU said changes to the Pacific Walker Circulation – shifts in atmospheric patterns above the Pacific Ocean – have implications for El Niño and La Niña events in

Human greenhouse gas emissions aren’t driving major changes in massive air circulation across the Pacific Ocean, but reduction in aerosols over time could lead to a weakening of processes that influence the length and frequency of El Niño climate events.

The Pacific Walker Circulation, a loop of air that circulates over the Pacific Ocean, determines how much rain and heat Australia gets. As it changes, our lives are likely to be impacted.
