ANU02: Fire Weather in Southeast Australia

July 19, 2021 1:36 pm Published by Comments Off on ANU02: Fire Weather in Southeast Australia

The passage of weather fronts over southeast Australia during the spring and summer increases the risk of dangerous fire weather. This project will carry out an analysis of observational data to determine a method for characterising when fronts have passed through southeast Australia.

Research brief: Drones used to map thunderstorms

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.

Research brief: Urban heat island effect amplifies Sydney heatwaves

July 14, 2021 1:46 pm Published by Comments Off on Research brief: Urban heat island effect amplifies Sydney heatwaves

This research uses Sydney, Australia’s largest city, as a test case for our new configuration of the Weather and Research Forecasting model run at a very high resolution of 800 m with a new urban classification scheme that describes the complexity of Sydney’s built environment.

Research brief: How ENSO affects the North Atlantic

July 14, 2021 1:23 pm Published by Comments Off on Research brief: How ENSO affects the North Atlantic

In this study, CLEX researchers and colleagues showed that the North Atlantic sea-surface temperature response to ENSO is nonlinear with respect to the strength of the sea-surface temperature forcing in the tropical Pacific.

Research brief: How cumulus convection changes with extreme rainfall

July 13, 2021 2:59 pm Published by Comments Off on Research brief: How cumulus convection changes with extreme rainfall

CLEX researchers used data from a wind profiler radar pair at Darwin, Australia, to determine the characteristics of individual up- and downdrafts observed at the site. They found updrafts with 5km vertical heights with extreme rain rates.

The latest global climate models present challenges for generating climate projections

June 23, 2021 10:41 am Published by Comments Off on The latest global climate models present challenges for generating climate projections

Climate sensitivity describes how sensitive the Earth’s temperature is to a doubling of the amount of carbon dioxide in the atmosphere. One measure of climate sensitivity for projections of future climate is the Equilibrium Climate Sensitivity (ECS). ECS is the increase in the global average temperature between the pre-industrial era and a future doubled carbon dioxide climate once equilibrium of the climate has been reached.

Developing and publishing open-source software and my experience with an open peer-review process

June 17, 2021 8:55 am Published by Comments Off on Developing and publishing open-source software and my experience with an open peer-review process

Navid Constantinou developed a new Julia package that provides solvers for geophysical fluid dynamics problems in periodic domains. It was also the first time he had been involved in an open peer-review process, and this experience was "mind changing".
