Research Brief: ROME among the clouds with new radar metric

April 15, 2020 1:51 pm Published by Comments Off on Research Brief: ROME among the clouds with new radar metric

To better assess the degree of organisation in radar observations CLEX researchers developed the Radar Organisation Metric (ROME). ROME's statistical properties suggest it is able to distinguish between the degree of convective organisation, and it also captures different regimes of the monsoon in Northern Australia.

Don’t look to mature forests to soak up carbon dioxide emissions

April 15, 2020 11:21 am Published by Comments Off on Don’t look to mature forests to soak up carbon dioxide emissions

Models used to project future climate change, and impacts of climate change on plants and ecosystems, currently assume that mature forests will continue to absorb carbon over and above their current levels, acting as carbon sinks. The findings from this research suggest that those sinks may in actual fact be weaker or absent for forests on low-nutrient soils.

Research on the Antarctic stratospheric polar vortex is important for Australia’s seasonal forecasts

Research has established a link between Antarctic stratospheric winds and an increased risk of weather conducive to bushfires from late spring to early summer. Further research on the relationship between winds and ozone in the Antarctic stratosphere could improve seasonal forecasts for Australia.

Research brief: Simulating tropical cyclones with ACCESS

March 19, 2020 1:29 pm Published by Comments Off on Research brief: Simulating tropical cyclones with ACCESS

This two part paper examines the capacity of ACCESS to simulate tropical cyclone climatology and then used the same model to examine the relationship between climate variables and tropical cyclone formation.

Research brief: SSTs create biases in how ENSO appears in CMIP5 models

March 13, 2020 9:49 am Published by Comments Off on Research brief: SSTs create biases in how ENSO appears in CMIP5 models

A new study by CLEX researchers and colleagues shows that CMIP5 models as a group, when forced by observed sea surface temperatures underestimate, these atmospheric feedbacks on average by 23%. This underestimate can be linked to the wrong location at which climate models simulate the most important tropical circulation, called the Walker circulation.

Research brief: First observational analysis of SSW events shows winter impacts.

March 11, 2020 12:45 pm Published by Comments Off on Research brief: First observational analysis of SSW events shows winter impacts.

When the “Beast from the East” brought cold temperatures and heavy snowfall to western Europe in February and March 2018, a lot of people were quick to link the extreme weather to a sudden stratospheric warming (SSW) that had recently occurred. CLEX researchers found there was a surprising lack of research on the relationship between SSWs and climate extremes in Europe using observations, so they sought to look at this in more detail to see if this link can really be made.
