CLEX researchers with the Bureau of Meteorology have created a new 20-year-long regularly updated precipitation dataset for Australia using 50 radar sites. This will allow researchers to examine the climatology of extreme events, follow cloud processes, estimate hail size, determine cloud top height and much more.
CLEX researchers and colleagues have developed a downscaling methodology using the HiDRUS model that accurately projects future rainfall in 1km grids at six minute intervals. This will be a boon for urban planners who need to build infrastructure to cope with the different future heavy rainfall events that will occur in a changing climate.
CLEX researchers and colleagues revisit the quasi-equilibrium analytical framework introduced by Comins and McMurtrie (1993) and explore the consequences of specific model assumptions for ecosystem net primary productivity (NPP).
Using novel ocean glider technology, a team of researchers from France, Norway, and Australia observed small eddy-like lenses of cold water in July 2017 along the western Svalbard shelf in the Arctic.
New work published in Nature Communications develops a correction method that ensures the probability of climate extremes in the model simulations are consistent with real-world observations. In addition, it also corrects the rate of the long-term changes and the inter-annual variability so that it is consistent with observations.
New CLEX research finds land cover misclassifications over South East Asia based on remote sensing products have negligible impact on the outcomes of climate model experiments. However, land cover experiments that incorporate uncertainties must use large numbers of simulations to get robust results for rainfall and air temperature.
CLEX researchers find strong correlation between ozone hole size and Australian summer temperatures. While there is no causal link between the two, the changes are driven by the same source - ocean temperatures.
Thus study used satellite scatterometry to measure the horizontal component of winds over the sea surface in the Maritime Continent. It combined data with scatterometer to give additional insights into gravity wave structure in this region.
Natural variability has been found to play a role in the speed of warming of land surface temperatures. With indications that the negative Interdecadal Pacific Oscillation is now becoming positive, this suggests that the hiatus period is over and we are likely entering a phase of accelerated warming of global surface air temperatures.
The study proposes a conceptual model of lagoon island formation, which incorporates aeolian sedimentation and episodes of wave and tide over-wash. Although not part of the core CLEX program, this study represents an interesting multi-disciplinary application of our work on tropical storms to geomorphology.
