New book reveals how climate change affects ENSO

As a La Niña event intensifies in the Pacific, bringing increased rain to parts of Australia and a powerful hurricane season to the Tropical Atlantic, a new book reveals the dynamics and impacts of the El Niño Southern Oscillation (ENSO), the irregular cycle that switches the Pacific Ocean between these cool La Niña and warm El Niño events.

Research brief: tropics and SOUTHERN HEMISPHERE subtropics were drier in the mid‑Pliocene Warm Period

November 2, 2020 2:28 pm Published by Comments Off on Research brief: tropics and SOUTHERN HEMISPHERE subtropics were drier in the mid‑Pliocene Warm Period

New study shows November-to-March precipitation (when rainy season peaks over most of the Southern Hemisphere land mass) was significantly reduced both in the Southern Hemisphere tropics and subtropics due to a weakening of the subtropical convergence zones during the mid-Pliocene Warm Period.

Research brief: Tropical rainfall modelling errors decrease slowly, but storm resolving models may be the future

October 23, 2020 10:24 am Published by Comments Off on Research brief: Tropical rainfall modelling errors decrease slowly, but storm resolving models may be the future

An international team including CLEX researchers examined models used by the Intergovernmental Panel for Climate Change (IPCC) over three model phases linked to IPCC reports – CMIP3, CMIP5, and the most recent, CMIP6, to see if they improved representation of tropical rainfall.

Research brief: The Sensitivity of Atmospheric River Identification

October 20, 2020 9:43 am Published by Comments Off on Research brief: The Sensitivity of Atmospheric River Identification

CLEX researchers explore the challenges of identifying atmospheric rivers and find that detecting these events is highly variable according to resolution, and choice of the integrated water vapour transport thresholds. The uncertainties in a single detection method and data parameters may be as large as uncertainties across AR detection methodologies.

Research brief: IPCC review reveals climate impacts occur at lower temperatures than previously thought.

October 19, 2020 1:59 pm Published by Comments Off on Research brief: IPCC review reveals climate impacts occur at lower temperatures than previously thought.

An international review of IPCC reports since 2001 has found that as the science has improved with each report, a trend has appeared showing climate related impacts like heatwaves, the collapse of the West Antarctic ice sheet and coral bleaching are likely to occur at lower global mean temperatures than estimated in earlier reports.

Researchers call on Australian citizen scientists to collect storm data

Australia researchers are calling on storm chasers and members of the general public fascinated by severe weather to take part in a citizen science project that will help better capture the occurrence of extreme weather events and improve our ability to forecast them.

Research brief: Where does Australia’s rain come from?

September 4, 2020 8:46 am Published by Comments Off on Research brief: Where does Australia’s rain come from?

Where does our rain come from? For a drought-prone continent like Australia, and a country with communities and industries affected by drought and flooding rains, the answer to that question is of vital importance.
