This paper focuses on a case study to provide a methodology for how the costs associated with an extreme weather event may be shared between citizens and envisage how such a system could look in future.
In Melbourne, 50% of rainfall and 75% of extreme daily rainfall occurs on days with at least one linearly organized convective system. However, thunderstorms are often localized events, and much of the rainfall in a region falls over a short period of time. Furthermore, not all thunderstorms necessarily occur in lines, and organized storms that lead to extreme sub-daily rainfall may be different from those that lead to extreme daily rainfall. This projects aims to identify and categorize organizational structures linked with the most intense rainfalls in the region.
In 1891, Melbourne experienced one of its worst floods on record leading to extensive damage and many deaths. But what was this wayward weather system? How often do lows from our east coast drift westward, and what are their impacts in Victoria? How many of our most significant flooding events are associated with a pattern like this? And are these systems changing over time?
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.
CLEX researchers have developed Australia’s longest daily temperature record, identifying a decrease in cold extremes and an increase in heatwaves around Adelaide since 1838.
This project will explore the potential for developing site-based and event-based extreme weather indices for parametric crop insurance using reanalyses of atmospheric climate variables.
This project will use output from state-of-the-art climate simulations of the Last Millennium (850–2005 CE) to explore the long-term variability of an Australian climate driver of the student’s choice. The student will explore the natural variability of that driver to determine its long-term context, and compare with palaeoclimate reconstructions (proxies) where possible.
New study highlights local warming is expected to accelerate beyond the global average in mid latitude regions, especially in summer. Over oceans the rise will be below global average warming.
Central Argentina is home to some of the world's most extreme thunderstorms. Giant hail, flash flooding and severe lightning regularly impact the communities and famous vineyards. Joshua Soderholm joined 160 scientists to understand why.
Weather and climate extremes occur on a wide range of time and space scales. Weather extremes occur on shorter timescales and are regionally or locally specific while climate extremes tend to be on longer timescales and can impact a region through to the whole globe. This note provides a statement on what we know about how weather and climate extremes might change in the future.
