RP1 Weather & Climate Interactions Report – August 2021

August 13, 2021 2:24 pm Published by Comments Off on RP1 Weather & Climate Interactions Report – August 2021

The Weather and Climate Interactions Research Program is now bedded down, and work is beginning apace. We have also started to see our researchers bring their expertise to a range of stakeholders, peer networks, and the broader community.

Clemente produces summer cloud dataset from Himawari-8 images

April 13, 2021 2:05 pm Published by Comments Off on Clemente produces summer cloud dataset from Himawari-8 images

Clemente Lopez-Bravo has created two datasets – L1 and L2 – of satellite observations of cloud properties across Australia and the Maritime Continent. The datasets, which have been released for the scientific community, are at a 2km spatial resolution at hourly intervals and cover five Austral summers in the period from November 2015 to March 2020.

Research brief: Tickling climate models reveals their bad behaviour

In this work CLEX researchers aim to understand a few popular ways to parameterize convection. They extracted one vertical column from five different GCMs and lightly tickled (perturbed) it and then observed the responses.

Research brief: Evaluating Himawari-8 cloud products

While the data from Himiwari-8 provides very useful data on clouds at relatively high resolution, researchers need to know if it produced any biases, particularly around cloud-top height and cloud-top temperature, whose roles are critical in shaping Earth’s climate. CLEX researchers and Australian colleagues compared the Himawari-8 data for both of these measures with existing datasets.

PhD opportunity: The role of wave-cloud coupling in shaping patterns of clouds

September 30, 2019 9:19 am Published by Comments Off on PhD opportunity: The role of wave-cloud coupling in shaping patterns of clouds

This project analyzes satellite images and other observational data to study two-way interactions between convection and tropospheric waves. In particular, it investigates how these interactions influence patterns of convection and clouds. Numerical experiments in the form of high-resolution simulations are designed to support the results.

Research brief: Ice particle numbers plummet in Southern Ocean’s clouds

October 19, 2018 1:20 pm Published by Comments Off on Research brief: Ice particle numbers plummet in Southern Ocean’s clouds

In 2016, Centre of Excellence for Climate Extremes researchers and colleagues measured Southern Ocean INPs for the first time in over four decades. The numbers of these particles were extremely low compared to other oceans and 100 times lower than the previous Southern Ocean measurement program conducted in the 1970s.

UNSW3: Understanding the vertical mixing of water vapour

August 14, 2018 4:49 pm Published by Comments Off on UNSW3: Understanding the vertical mixing of water vapour

In this project, we seek to utilise 40 years of observations of water vapour profiles from the global radiosonde network to improve our process level understanding of water vapour mixing. The applicant is expected to know the basics of atmospheric physics and statistics. Some knowledge of data processing tools will be an advantage.
