The cost of weather-related disasters in Australia is increasing every decade.
La Niña conditions first began in spring 2020 and continued until early autumn 2021. A second La Niña developed in spring 2021 and persisted through early winter 2022. Known as a “double-dip” La Niña, back-to-back Australian summers with La Niña conditions are not uncommon and have occurred in about 50% of all past La Niña events.
Researchers are currently trying to understand the characteristics and types of locally damaging wind events that have occurred using historical data and simulations from computer models.
The heatwave was fuelled by a lack of weather conditions which have a “cooling” effect in this region.
The ARC Centre of Excellence for Climate Extremes is conducting research into how climate change is affecting severe convective storms including hailstorms.
This extreme flooding caused devastating consequences and enormous economic losses to the residents of Eugowra.
Atmospheric rivers played an important role in these heavy rainfall events, providing the large source of moisture which was dumped over Sydney.
As with many climate extremes during 2022, record cold daytime temperatures resulted from the prolonged presence of a cut-off low pressure system.
There were a series of high-impact weather events in the Northern Hemisphere in June and July 2021.
Antarctic sea ice affects global climate by reflecting sunlight, influencing air-sea interactions and ocean circulation.
