Mathilde Ritman describes her journey as a second-year undergraduate student into a CLEX research project with Linden Ashcroft. It led to a publication, a massive learning curve in coding, stints with the Bureau of Meteorology and CSIRO, and opened a path to a career in climate science.

Research brief: Why Melbourne’s worst storms come in lines

September 3, 2021 8:51 am Published by Comments Off on Research brief: Why Melbourne’s worst storms come in lines

It has long been suggested in the literature, and discussed casually by meteorologists, that rainfall in Melbourne often occurs as lines of precipitation. However, this had yet to be quantified. CLEX researchers analysed 15 years of radar data from the Australian Radar Archive, using an objective method to identify and track these ‘linear systems’ based on radar reflectivity, size, and shape characteristics.

BOM03: realise added value of bias correction and downscaling methods on hydrological projections

August 23, 2021 11:35 am Published by Comments Off on BOM03: realise added value of bias correction and downscaling methods on hydrological projections

Hydrological impact studies analyse the effects of climate change on hydrological variables, such as changes in soil moisture, streamflow or hydrological extremes. This project aims to investigate the realised added value effect of model bias correction and downscaling methods on hydrological projections for Australia.

BOM02: Impacts of hydrological extremes using machine learning

August 23, 2021 8:36 am Published by Comments Off on BOM02: Impacts of hydrological extremes using machine learning

This project will explore the use of supervised and unsupervised statistical learning methods (such as neural networks, random forest, clustering) to understand the impact of climate change on hydrological extremes and/or to simulate downstream impacts on affected sectors, such as agriculture, energy, transport, water resources management.

BOM01: Effects of compound hot and dry events on agricultural production in australia

August 23, 2021 8:24 am Published by Comments Off on BOM01: Effects of compound hot and dry events on agricultural production in australia

The aim of this project is to investigate the effect of compound hot and dry events on agricultural production in Australia, and to assess the predictability of yield losses due to compound events using seasonal climate and hydrological forecasts. The outcome of the project may inform the development of seasonal forecasts of hydro-climatic risk indicators for agricultural production in Australia.

How a 6-week project became two years of research

In this report CMS welcomes Annette Hirsch to the team, alerts users to retracted ERA5 data, continues work on ACCESS-ESM1.5, and looks at changes to NCI processes, and CLEX data management practices and training.

Research brief: Revisiting the 1888 Centennial Drought

To shed more light on short droughts of the past, CLEX researchers took advantage of a newly released dataset from the Bureau of Meteorology to re-examine the infamous Centennial Drought of 1888. Using the new dataset along with historical station data, they analysed monthly rainfall variability across south eastern Australia throughout 1888.

CLEX Research Vital Input to IAG/NCAR report

December 12, 2020 6:40 pm Published by Comments Off on CLEX Research Vital Input to IAG/NCAR report

In September 2020, IAG and NCAR released a report Severe Weather in a Changing Climate (second edition), which incorporated research findings from numerous CLEX researchers. CLEX feedback also led to the incorporation of a new section on connected extremes in this report, highlighting the value of research into weather extremes.
