Research brief: The Sensitivity of Atmospheric River Identification

October 20, 2020 9:43 am Published by Comments Off on Research brief: The Sensitivity of Atmospheric River Identification

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.

Research brief: How uncertainties in data and drought indices affect drought identification

September 24, 2020 10:22 am Published by Comments Off on Research brief: How uncertainties in data and drought indices affect drought identification

CLEX researchers examined the uncertainties of the input data of three commonly used drought indices, with the data coming from different sources, including observations and reanalysis. The ability of these indices to detect drought was assessed against soil moisture from multiple global land surface models.

Research brief: The biogeochemical structure of Southern Ocean mesoscale eddies.

August 3, 2020 4:48 pm Published by Comments Off on Research brief: The biogeochemical structure of Southern Ocean mesoscale eddies.

CLEX researchers used real-world observations with satellite observations to calculate the quantity of nutrients carried into the Subantarctic Zone by mesoscale eddies. They found these eddies carried high nitrate and low silicate waters into the Subantarctic Zone.

Research Brief: ROME among the clouds with new radar metric

April 15, 2020 1:51 pm Published by Comments Off on Research Brief: ROME among the clouds with new radar metric

To better assess the degree of organisation in radar observations CLEX researchers developed the Radar Organisation Metric (ROME). ROME's statistical properties suggest it is able to distinguish between the degree of convective organisation, and it also captures different regimes of the monsoon in Northern Australia.

Research brief: How dry soils amplify Australian heatwaves

February 11, 2020 11:39 am Published by Comments Off on Research brief: How dry soils amplify Australian heatwaves

CLEX researchers found that regions where there is a larger drying trend tend to be more sensitive to land water availability and have more heatwave days. They found that the effect of dry soils before a heatwave varies considerably across Australia.

Research brief: New downscaling approach will help urban planners prepare for future rainfall

May 31, 2019 2:30 pm Published by Comments Off on Research brief: New downscaling approach will help urban planners prepare for future rainfall

CLEX researchers and colleagues have developed a downscaling methodology using the HiDRUS model that accurately projects future rainfall in 1km grids at six minute intervals. This will be a boon for urban planners who need to build infrastructure to cope with the different future heavy rainfall events that will occur in a changing climate.
