Research brief: Urban heat island effect amplifies Sydney heatwaves

July 14, 2021 1:46 pm Published by Comments Off on Research brief: Urban heat island effect amplifies Sydney heatwaves

This research uses Sydney, Australia’s largest city, as a test case for our new configuration of the Weather and Research Forecasting model run at a very high resolution of 800 m with a new urban classification scheme that describes the complexity of Sydney’s built environment.

Research brief: How ENSO affects the North Atlantic

July 14, 2021 1:23 pm Published by Comments Off on Research brief: How ENSO affects the North Atlantic

In this study, CLEX researchers and colleagues showed that the North Atlantic sea-surface temperature response to ENSO is nonlinear with respect to the strength of the sea-surface temperature forcing in the tropical Pacific.

Research brief: How cumulus convection changes with extreme rainfall

CLEX researchers used data from a wind profiler radar pair at Darwin, Australia, to determine the characteristics of individual up- and downdrafts observed at the site. They found updrafts with 5km vertical heights with extreme rain rates.

Research brief: The rare event that amplified the dry Australian spring of 2019 is unlikely to happen again

May 27, 2021 12:11 pm Published by Comments Off on Research brief: The rare event that amplified the dry Australian spring of 2019 is unlikely to happen again

An unusual southern stratospheric warming event amplified the conditions that led to the Black Summer bushfires of 2019/20. CLEX researchers explored how frequently these rare warming events may occur with climate change.

Research brief: Pathways and pitfalls in extreme attribution

May 26, 2021 11:57 am Published by Comments Off on Research brief: Pathways and pitfalls in extreme attribution

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.

Research brief: How internal waves drive mixing in the Southern Ocean

May 6, 2021 12:35 pm Published by Comments Off on Research brief: How internal waves drive mixing in the Southern Ocean

Major gaps exist in our understanding of the pathways between the generation and the breaking of internal waves in the Southern Ocean. This has important implications for the distribution of internal wave-driven turbulent mixing, for the sensitivity of ocean mixing rates, and for the representation of ocean mixing in numerical models.
