UMELB03: Storm organisation and short duration extreme rainfall in Melbourne

August 18, 2021 12:06 pm Published by Comments Off on UMELB03: Storm organisation and short duration extreme rainfall in Melbourne

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.

UMELB02: Melbourne flooding and ‘easterly moving’ weather systems

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?

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.

ANU01: Are recent climate extremes really ‘extreme’?

July 15, 2019 1:00 am Published by Comments Off on ANU01: Are recent climate extremes really ‘extreme’?

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.

Chasing some of the largest hailstorms in the world

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.
