In this study, the researchers used a high-resolution numerical simulation of the cold tongue region to show that strong turbulent mixing occurs not only on the Equator, but also off the Equator on the edge of the cold tongue associated with passing energetic oceanic waves with periods of 15-40 days known as Tropical Instability Waves.

In 2019, Ryan travelled to IUGG, NCAR in Boulder and LOCEAN in France. Here he describes how to get the most out of trips like these and considers the carbon emissions impacts.
Research brief: How tropical Indo-Pacific processes drive ocean heat into Atlantic meridional circulationNovember 26, 2019 10:26 am Comments Off on Research brief: How tropical Indo-Pacific processes drive ocean heat into Atlantic meridional circulation
Solar heating of surface waters in the tropical Indian and Pacific oceans, along with turbulent mixing that moves this heat into the colder deep-reaching Atlantic meridional overturning circulation, play a crucial role in shaping oceanic heat transport pathways
CLEX researchers examined the behaviour of a passive tracer released near the seafloor in an idealised two-dimensional flow driven by bottom-enhanced turbulence.
Climate recorded in seawater: A workshop on water-mass transformation analysis for ocean and climate studiesAugust 2, 2019 2:30 am Comments Off on Climate recorded in seawater: A workshop on water-mass transformation analysis for ocean and climate studies
In early February 2019 an international cohort of around 40 oceanographers, marine biogeochemists and climate modellers gathered at UNSW to discuss the use of the Water Mass Transformation (WMT) framework for studies of ocean physics, biogeochemistry and climate. The workshop was an initiative of several CLEX early career researchers and gained interest from a diverse international community.
The summer student on this project will make use of recent observations and combine these novel machine learning and image processing techniques to understand the drivers of recent ocean change.
The ocean plays a critical role in the climate system by transferring heat from the tropics toward the poles, helping to regulate regional climates. How this heat transport may change in the future remains a first order question in climate science.
We seek a student to help develop a simple mathematical model to describe the ocean’s octopus like shape and what the movement of its tentacles tells us about climate change.
What would happen if we suddenly warmed the ocean at the sea-surface? Would suddenly cooling it down cause an equal and opposite response? The student will work towards developing novel theories to describe the ocean’s response to extreme perturbations. These theories are needed to understand the ocean's role in transient climate change.
