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.

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.

Observations over Kuala Lumpur and climate model experiments reveal how the warmth of cities compared to the surrounding area enhance extreme rainfall events.
