Research brief: New Zealand’s costliest floods caused by atmospheric rivers
by Alvin Stone | Mar 3, 2021 | Research briefs, RP1 Extreme Rainfall | 0
The largest rivers on Earth are not on the ground, but in the sky. Our new study, published in Environmental Research Letters, showed that nine out of ten of the most expensive floods in New Zealand (2007-2017) occurred during an Atmospheric River event, and seven to all ten of the top ten most extreme rainfall events at eleven different locations occurred during Atmospheric Rivers.

by Alvin Stone | Feb 12, 2021 | Research briefs, RP3 Drought | 0 |
In this study, the researchers propose a reporting format for leaf-level gas exchange data and metadata to provide guidance to data contributors on how to store data in repositories to maximise their discoverability, facilitate their efficient reuse, and add value to individual datasets.
Read MoreResearch brief: The Black Summer and COVID impacts on Sydney and Melbourne air quality.
by Alvin Stone | Feb 12, 2021 | Research briefs, RP4 Climate Variability | 0
CLEX researchers and colleagues quantified the air quality impact of the Black Summer bushfires of 2019/20 and COVID-19 in the south-eastern states of Victoria and New South Wales (NSW) using a meteorological normalisation approach.
Read MoreResearch brief: Most Australian heatwaves from moving systems, not blocked systems
by Alvin Stone | Feb 12, 2021 | Research briefs, RP2 Heatwaves and cold outbreaks | 0
The majority of heatwaves affecting south-eastern Australia are part of large and strong weather systems propagating across Australia, and not due to stationary or blocked weather systems as seen in some other regions of the world.
Read MoreResearch brief: How gravity waves impact thunderstorm formation
by Alvin Stone | Feb 11, 2021 | Research briefs, RP1 Extreme Rainfall | 0
Storms cause ripples in the wind that travel upwards and away from the clouds, much like a stone causes ripples when it is thrown in a pond. These can then affect the temperature and winds around the storms and make them grow, last longer, or die earlier.
Read MoreResearch brief: ACCESS1 outperforms POAMA forecasting SPCZ
by Alvin Stone | Feb 10, 2021 | Research briefs, RP1 Extreme Rainfall | 0
The researchers analysed the performance of the ACCESSS1 seasonal forecast model to predict the SPCZ position and rainfall over the period 1990-2012. ACCESSS1 performed better in simulating the SPCZ than the previous model, POAMA.
Read MoreResearch brief: New global land-based precipitation dataset
by Alvin Stone | Feb 4, 2021 | Research briefs, RP1 Extreme Rainfall | 0
CLEX researchers have developed a new global land-based daily precipitation dataset called Rainfall Estimates on a Gridded Network – REGEN – aimed at facilitating studies to understand changes and variability in several aspects of daily precipitation distributions, extremes and measures of hydrological intensity.

by Alvin Stone | Jan 15, 2021 | Research briefs, RP4 Climate Variability | 0
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.
Read MoreResearch brief: Revisiting the 1888 Centennial Drought
by Alvin Stone | Jan 12, 2021 | Research briefs, RP3 Drought | 0
To shed more light on short droughts of the past, CLEX researchers took advantage of a newly released dataset from the Bureau of Meteorology to re-examine the infamous Centennial Drought of 1888. Using the new dataset along with historical station data, they analysed monthly rainfall variability across south eastern Australia throughout 1888.
Read MoreResearch brief: The interaction of ocean basins may improve long-term climate predictions
by Alvin Stone | Dec 17, 2020 | Research briefs, RP4 Climate Variability | 0
An international team of authors led by NCAR scientist and CLEX PI Jerry Meehl, along with CLEX CIs and AIs, propose that the Pacific and Atlantic ocean basins are mutually interactive, with each basin influencing and responding to processes in the other basin.
Read MoreResearch brief: Indian Ocean warming modulates global atmospheric circulation trends
by Alvin Stone | Nov 27, 2020 | Research briefs, RP4 Climate Variability | 0
Using atmospheric model experiments, researchers have shown that the warming of the tropical Indian Ocean relative to the other two tropical ocean basins can effectively control Walker Circulation changes in the Pacific and Atlantic oceans and influence climate far beyond the Indian Ocean region.
Read MoreResearch brief: Land surface models struggle to reproduce evaporative processes
by Alvin Stone | Nov 27, 2020 | Research briefs, RP3 Drought | 0
This paper details a new approach to evaluating the performance of land surface models, the component of climate and weather models that simulates land surface processes. It focuses on the cycle of solar radiation during daylight hours and how the energy from the sun is exchanged between the land surface and lower atmosphere.
