Research brief: How Central Pacific El Niños affect rainfall over the Murray Darling basin

March 18, 2021 1:16 pm Published by Comments Off on Research brief: How Central Pacific El Niños affect rainfall over the Murray Darling basin

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.

Research brief: Do aerosols produced by coral reefs influence climate?

March 18, 2021 11:57 am Published by Comments Off on Research brief: Do aerosols produced by coral reefs influence climate?

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.

Research brief: How climate change impacts Marine heatwaves around Australia and New Zealand

March 15, 2021 10:10 am Published by Comments Off on Research brief: How climate change impacts Marine heatwaves around Australia and New Zealand

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.

Research brief: What drives extreme heat events in spring?

March 9, 2021 3:38 pm Published by Comments Off on Research brief: What drives extreme heat events in spring?

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.

Research brief: How El Niños impact climate in the southwest Indian OCean

March 9, 2021 3:13 pm Published by Comments Off on Research brief: How El Niños impact climate in the southwest Indian OCean

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.

Research brief: Unlocking the keys to ocean literacy

March 8, 2021 1:54 pm Published by Comments Off on Research brief: Unlocking the keys to ocean literacy

As part of the Future Seas project, this paper summarizes knowledge and perspectives on ocean literacy from a range of disciplines, including but not exclusive to marine biology, socio-ecology, philosophy, technology, psychology, oceanography and human health.

Research brief: Warmer oceans amplify LENGTH AND FREQUENCY of coastal marine heatwaves

March 5, 2021 1:19 pm Published by Comments Off on Research brief: Warmer oceans amplify LENGTH AND FREQUENCY of coastal marine heatwaves

CLEX researchers found coastal marine heatwave hotspots were concentrated along the Mediterranean Sea, Japan Sea, south‐eastern Australia and the north‐eastern coast of the United States. They also found the frequency of these events and their duration globally increased by 1–2 events per decade and 5–20 days per decade. Most of the marine heatwave hotspots identified were associated with high upward trends.

Research brief: Ring like structure in cyclone leads to rapid intensification of surface winds

March 5, 2021 11:19 am Published by Comments Off on Research brief: Ring like structure in cyclone leads to rapid intensification of surface winds

The most intense and destructive tropical cyclones generally go through a period of rapid intensification, where "rapid" means that the near-surface winds increase by more than 15 m/s (54km/hr) in 24 hrs. However, the physical processes by which storms rapidly intensify are not well understood. This study uses very high-resolution simulations with the UK Met Office Unified Model of the 2016 north-Pacific tropical cyclone, Nepartak, to explore the processes responsible for its rapid intensification.

Research brief: New Zealand’s costliest floods caused by atmospheric rivers

March 3, 2021 3:45 pm Published by Comments Off on Research brief: New Zealand’s costliest floods caused by atmospheric rivers

The largest rivers on Earth are not on the ground, but in the sky. Our new study, published in Environmental Research Letters, showed that nine out of ten of the most expensive floods in New Zealand (2007-2017) occurred during an Atmospheric River event, and seven to all ten of the top ten most extreme rainfall events at eleven different locations occurred during Atmospheric Rivers.

Research brief: New reporting format for leaf-level gas exchange data

February 12, 2021 2:05 pm Published by Comments Off on Research brief: New reporting format for leaf-level gas exchange data

In this study, the researchers propose a reporting format for leaf-level gas exchange data and metadata to provide guidance to data contributors on how to store data in repositories to maximise their discoverability, facilitate their efficient reuse, and add value to individual datasets.
