As a La Niña event intensifies in the Pacific, bringing increased rain to parts of Australia and a powerful hurricane season to the Tropical Atlantic, a new book reveals the dynamics and impacts of the El Niño Southern Oscillation (ENSO), the irregular cycle that switches the Pacific Ocean between these cool La Niña and warm El Niño events.
Australia researchers are calling on storm chasers and members of the general public fascinated by severe weather to take part in a citizen science project that will help better capture the occurrence of extreme weather events and improve our ability to forecast them.
High resolution ocean modelling has found the world’s strongest ocean currents, which play key roles in fisheries and ocean ecosystems, will experience more intense marine heatwaves than the global average over coming decades.
Climate change will affect prescribed burning days in the future. Unexpectedly, it is not all bad news, but as the coming century progresses there are definitely changes ahead for our firefighters in Australia when it comes to preparing for a fire season, especially along the east coast of Australia.
CLEX researchers and colleagues have highlighted the need for the development of systems to predict marine heatwaves, which are a growing threat to marine ecosystems and industries as the climate changes.
Tiny microbes at the base of the ocean food chain will be increasingly affected by marine heatwaves as the climate changes.
The most advanced and comprehensive analysis of climate sensitivity yet undertaken has revealed with more confidence than ever before how sensitive the Earth’s climate is to carbon dioxide. The range has been reduced from 1.5°C-4.5°C down to 2.3°C-4.5°C.
The first comprehensive worldwide assessment of heatwaves down to regional levels has revealed that in nearly every part of the world heatwaves have been increasing in frequency and duration since the 1950’s. The research has also produced a new metric, cumulative heat, which reveals exactly how much heat is packed into individual heatwaves and heatwave seasons.
Kim Reid describes everything you ever wanted to know about atmospheric rivers, and then some. Front, Warm Conveyor Belt, Atmospheric River, Tropical Moisture Exports and Flexible Tubes. Are these phrases describing different phenomenon or are they merely alternative names for same system?
This project seeks to better understand the changing nature of Australian droughts by synthesising satellite and ground observations in combination with state-of-the-art climate model projections.
