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.
Lee Constable interviews Prof Christian Jakob about what we don't know about climate change for her channel on the Cimpatico Studios platform, Climate Australia.
Research brief: tropics and SOUTHERN HEMISPHERE subtropics were drier in the mid‑Pliocene Warm PeriodNovember 2, 2020 2:28 pm 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 futureOctober 23, 2020 10:24 am 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.
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.
CLEX researchers find rapidly intensifying hurricanes may become more frequent in a future warmer climate and the speed of this increase in intensity will continue to accelerate as the world's oceans continue to warm.
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.
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.
Comparing past and future changes in Southern Hemisphere monsoons has revealed how they will alter with climate change under a business-as-usual scenario.
Organised nighttime thunderstorms can sometimes occur without a surface cold pool. CLEX researchers investigated how this could occur and still support storms.
