Until now, flash drought research has been on the regional scale and has been limited to observations and reanalyses. CLEX researchers have been the first to examine flash drought in climate models.

Researchers report gaseous elemental mercury observations from Churchill, in the heart of the Latrobe Valley’s coal power generation fleet from June of 2013. Mercury values both day and night were significantly higher than the Southern Hemispheric average values.

This paper used statistical techniques to investigate changes in extreme climate events that currently occur, on average, only once every 20 years. These techniques are applied to data related to heat, rainfall, drought and conditions conducive to bushfires and thunderstorms from detailed climate modelling commissioned by NSW and ACT Governments.

In this study, researchers combine techniques from climate modelling and aircraft aerodynamics software to uncover mechanisms responsible for generating the Amundsen Sea Low pressure near Antarctica.

In this study, the researchers used a high-resolution numerical simulation of the cold tongue region to show that strong turbulent mixing occurs not only on the Equator, but also off the Equator on the edge of the cold tongue associated with passing energetic oceanic waves with periods of 15-40 days known as Tropical Instability Waves.

This research around central Pacific El Niños is important for agricultural and water resources planning efforts in the Murray Darling Basin region and may help with seasonal prediction efforts to predict drought‐breaking rain such as occurred in early 2020.

Coral reefs are known to produce a chemical called dimethyl sulfide (DMS), which, when released into the atmosphere, can help form or grow tiny particles known as aerosols. Currently, this source of aerosols produced by coral reefs is unaccounted for in climate science and hence the impact of coral reef extinction on aerosols and climate is unknown.

This study uses a high‐resolution climate model to investigate how and why marine heatwaves would change for the Australian region. The relative impacts of increases on background ocean temperature and changes to intrinsic temperature variations are compared.

Maximum temperatures in Australia during spring have exceeded historic records on multiple occasions in recent years. Understanding what drives these high temperatures may lead to better forecasts of extreme heat in the future.

El Niño effects are communicated to the Indian Ocean via both large‐scale atmospheric circulation changes over the southern tropical ocean basin and via disturbances to sea‐levels along the coast of Western Australia. CLEX researchers investigated these remote ENSO influences in a state‐of‐the‐art climate model.
