Research brief: How internal waves drive mixing in the Southern Ocean

May 6, 2021 12:35 pm Published by Comments Off on Research brief: How internal waves drive mixing in the Southern Ocean

Major gaps exist in our understanding of the pathways between the generation and the breaking of internal waves in the Southern Ocean. This has important implications for the distribution of internal wave-driven turbulent mixing, for the sensitivity of ocean mixing rates, and for the representation of ocean mixing in numerical models.

Research brief: An assessment of global fire-vegetation models

April 30, 2021 12:34 pm Published by Comments Off on Research brief: An assessment of global fire-vegetation models

An international team of researchers performed a systematic evaluation of simulations made by nine FireMIP models in order to quantify their ability to reproduce a range of fire and vegetation benchmarks.

Research brief: El Niño variations have little impact on terrestrial carbon cycle

April 30, 2021 12:16 pm Published by Comments Off on Research brief: El Niño variations have little impact on terrestrial carbon cycle

Different expressions of El Niño do affect interannual variability in the terrestrial carbon cycle. However, the effect over longer timescales is small. This means the changing frequency of these two types of El Niño events may be of little importance in terms of robustly simulating the future terrestrial carbon cycle.

Research brief: Latrobe Valley soil contamination some of the worst in the world

Researchers report gaseous elemental mercury observations from Churchill, in the heart of the Latrobe Valley’s coal power generation fleet from June of 2013. Mercury values both day and night were significantly higher than the Southern Hemispheric average values.

Research brief: Extreme events in SE Australia to increase in frequency by 2100

March 25, 2021 12:01 pm Published by Comments Off on Research brief: Extreme events in SE Australia to increase in frequency by 2100

This paper used statistical techniques to investigate changes in extreme climate events that currently occur, on average, only once every 20 years. These techniques are applied to data related to heat, rainfall, drought and conditions conducive to bushfires and thunderstorms from detailed climate modelling commissioned by NSW and ACT Governments.

Research brief: The mystery of vertical mixing in the eastern Pacific cold tongue

March 18, 2021 2:07 pm Published by Comments Off on Research brief: The mystery of vertical mixing in the eastern Pacific cold tongue

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.
