The overarching goal of the Colorado State University Convective CLoud Outflows and UpDrafts Experiment (C3LOUD-Ex) was to enhance our understanding of deep convective storm processes and how they are represented in numerical models. Pivotal to the experiment was a novel “Flying Curtain” strategy.

Organised nighttime thunderstorms can sometimes occur without a surface cold pool. CLEX researchers investigated how this could occur and still support storms.
CSIRO02: Analysing long tide gauge records in Australia in conjunction with the 20th Century reanalysis to better understand how extreme events and by association extreme sea level events are changingAugust 6, 2020 1:46 pm Comments Off on CSIRO02: Analysing long tide gauge records in Australia in conjunction with the 20th Century reanalysis to better understand how extreme events and by association extreme sea level events are changing
Understanding historical changes in extreme sea levels is necessary for the accurate projection of their changes over the next century. This project will look at digitized sea level data, to better understand the causes of extreme sea levels the southern Australian region and how these events vary over the duration of the record.
A new paper by Martin Jucker and colleagues reveals the choice of a particular convection-resolving model (CRM) has a much larger impact on the results than increasing resolution. It also suggests the behaviour of CRMs is tied to model internals instead of the phenomena they are trying to reproduce.
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.
From November 13-December 17, 2019, Sonny Truong took part in an observational voyage aboard the RV Investigator 30kms off the coast of Darwin. It was a voyage that featured some firsts for this atmospheric scientists and resulted in some great research and a spectacular time-lapse video of a storm forming and dissipating out to sea.
Onboard the RV Investigator as part of a scientific voyage over Christmas and new year, Rob Warren encountered a spectacular storm and performed research that will continue to improve Australia's radar network.
The objective of the project is to use a combination of station-based measurements and reanalyses (e.g. BARRA, ERA-5) to create a climatology of precipitable water for Australia. After creating the dataset, the student will also analyse trends and variability.

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.
