In a recent CLEX study, published in Climatic Change, researchers discuss the choices taken at each step, which may affect the final outcome and usefulness of extreme event attribution analyses.

Briefing note 13: How might Australia contribute to a next-generation global climate modelling facility?May 19, 2021 11:57 am Comments Off on Briefing note 13: How might Australia contribute to a next-generation global climate modelling facility?
The Royal Society has called for an international next-generation climate modelling centre (pdf), based on new cutting-edge high-performance computing and data services to support efforts toward net-zero emissions and to enable effective climate adaptation.
Recent studies have debated whether the two types of sudden stratospheric warming – displacement events when the vortex is displaced off the Pole and split events when the vortex splits into two smaller vortices – have differing near-surface impacts.
An international team of researchers performed a systematic evaluation of simulations made by nine FireMIP models in order to quantify their ability to reproduce a range of fire and vegetation benchmarks.
Welcome to the first Weather and Climate Interactions RP report. The new program name is simply a result of rationalising CLEX’s continuing research program under new headings that more clearly delineate the focus of the work we do.
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.
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 work CLEX researchers aim to understand a few popular ways to parameterize convection. They extracted one vertical column from five different GCMs and lightly tickled (perturbed) it and then observed the responses.
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.
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.
