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.
Martin Jucker writes about his latest creation, Iceberg, a database/scientific journal that comes with a doi but which focuses on scientific logbooks, manuals, experiments, code, a knowledge base for best practice and a record of things to avoid. The aim is to help scientists stop repeating the mistakes of colleagues who may have attempted the very same research you are performing now.
Martin Jucker (UNSW) gives an overview of using Paraview to visualise climate datasets.
The evidence is clear: the impacts of global warming are increasing, and to reduce them, we require a deep and rapid cut in greenhouse gas emissions.
The 2022 Hunga Tonga volcanic eruption produced the equivalent of 60,000 Olympic swimming pools of water vapor, which ended up in the stratosphere. Researchers have studied its impact on climate and suggest that it could lead to unusual winter weather for years to come.
The Southern Annular Mode (SAM) is the main mode of variability in the Southern Hemisphere. It manifests itself via a poleward shift of the band of strong westerly winds called the jet stream, and has known impacts on rainfall and surface temperatures throughout the Southern Hemisphere. This project will investigate whether the temperature structure in the lower stratosphere just above the tropopause has an influence on the SAM, and if so, tries to quantify its influence. This is based on... View Article
Our atmosphere, oceans and lands are constantly interacting with each other.
Originally published by Scimex The chemicals in bushfire smoke can enhance the activation of molecules that destroy ozone, according to Australian research which warns that the findings increase concern that more frequent and intense bushfires could delay the ozone hole recovery in a warming world. Previous research has shown that the smoke from the 2019-2020 Black Summer bushfires changed the chemical composition of the upper atmosphere, including a decline in the levels of ozone, but this new research looks at how...

CLEX researchers have overturned a scientific paradigm that has existed for 50 years. New research published in Nature Geoscience shows the massive convection caused by the ocean just north of Australia, causes a chain reaction that is strong enough to put an almost permanent dent in the powerful winds that circle the Antarctic.
An unusual southern stratospheric warming event amplified the conditions that led to the Black Summer bushfires of 2019/20. CLEX researchers explored how frequently these rare warming events may occur with climate change.
