What’s behind Australia’s shifting rainfall? New study explores weather objects
Australia’s rainfall is changing in distinct and important ways. Summers in the tropical north are getting wetter, while winters in the southeast are becoming drier. New research led by Dr Chenhui Jin at Monash University has taken a fresh look at the weather systems that modulate seasonal rain across the continent, helping to explain the…

Future rainfall and atmospheric rivers: Why thresholds matter in a warmer world
As the world continues to warm, the atmosphere will hold more moisture. That simple fact is reshaping how we think about rain, especially the powerful, moisture-laden weather systems known as atmospheric rivers. Atmospheric rivers are long, narrow bands of concentrated moisture in the sky. When they pass over land, they can bring much-needed rain to…

An uncertain future for the Antarctic Slope Current
Scientists are working to better understand a risk to Antarctica’s future, after finding climate change could significantly alter the ocean current protecting the frozen continent from warmer waters further north. New research published in Geophysical Research Letters predicts the melting of Antarctic ice will alter the Antarctic Slope Current, estimating it will be around 50…

A regional climate model for high-impact weather
Australia’s climate simulator (ACCESS-NRI) has released a fully supported version of a regional climate model that enables researchers to understand high-impact weather events like hurricanes, floods and droughts, which are not captured by the wide-angle lens of global climate models. Regional climate models are game changers when it comes to simulating high-impact weather events, and…
