The ocean’s much larger heat capacity acts as “memory” suppressing the atmosphere’s “high-frequency variability” (over time scales of weeks) while producing oceanic motions that vary over longer time scales. This paradigm aims to explain how low-frequency variability emerges in the ocean. But, recently, this paradigm has been challenged.

CLEX researchers introduced a novel methodology to examine the Southern Ocean's response to changing winds. They performed numerical simulations with a global ocean‐sea ice model suite that spans a hierarchy of spatial resolutions and driven by realistic atmospheric forcing conditions.
Multiple ARC Centres of Excellence came together to produce short videos about their researchers under the title Q&ARC. This is the CLEX version featuring Rishav Goyal, Stacey Hitchcock, Andy Hogg, and Nina Ridder.
CLEX researchers have demonstrated that ocean gyres (complete with a rich eddy field and strong western boundary current) occur even in the absence of wind forcing.
By comparing two models, CLEX researchers found that the current generation of convection parameterisations fail to replicate the random, chaotic nature of real-life turbulent convection.
In this work, CLEX researchers compared the performance of three ocean simulations – with low, medium and high resolutions – when representing marine heatwaves.
In January Andy Hogg attneded the annual DRAKKAR meeting. DRAKKAR, is the consortium which supports global ocean model configurations in Europe.
Chief Operating Officer, Stephen Gray, looks back on the annual workshop, discusses the new database to replace Clever and highlights the hump-day tips that have been developed by the Culture and Diversity committee.
The Climate Variability and Teleconnections Research Program has formed into three separate clusters – SAM, Tropical Variability and Oceans.
When Chilean researcher Dr Erasmo Macaya from Universidad de Concepción and Centro IDEAL stumbled upon foreign kelp washed up on an Antarctic beach, he knew he had found something significant. Research by an international, multidisciplinary team of scientists reveals just how important that finding was.
