The NESP Tropical Cyclone Projections Portal is a website with interactive features designed to provide information on the historical and projected climatology of tropical cyclone (TC) tracks in the s... moreouthern hemisphere, with a particular focus on the Australian region.
Tropical cyclone tracks are displayed from periods within baseline and future climates simulated by CMIP5 Global Climate Models using the RCP 8.5 emissions pathway, as well as those observed historically and published in the WMO version of the IBTrACS global best-track archive (v03r10). Various other products are derived from these data sets, including climatologies of and changes in:
- spatial density of number of TCs per decade;
- density of storms impacting on Australia's coastline;
- the simulated number and seasonal cycle of TCs;
- relationship of projected change in Australian-region TCs with changes in temperature and precipitation in the region.

Dynamically downscaled climate simulations for Victoria from 1961 to 2099 using the Conformal Cubic Atmospheric Model (CCAM) r3355. An ensemble of Global Climate Models were downscaled (ACCESS1-0, CN... moreRM-CM5, GFDL-ESM2M, HadGEM2, MIROC5 and NorESM1-M) from the CMIP5 archive for historical, RCP4.5 and RCP8.5, as well as downscaling ERA-Interim. Sea Surface Temperatures (SST) were bias corrected and the global atmosphere simulated at 50 km resolution with only SST forcing. The 50 km simulation was then downscaled to 5 km resolution over Victoria using CCAM’s variable resolution grid and a scale-selective filter. The dataset was created with support from Wine Australia, the Victorian Department of Environment, Land, Water and Planning, the University of Tasmania, as well as CSIRO Oceans and Atmosphere.less

A simulation of meteorology and fine particles (with a diameter < 2.5 um; PM2.5) was run on the NCI’s supercomputing facilities. The simulation was for December 2006 and comprised a global 5 km meteor... moreology simulation and a 10 km continental scale and nested 3 km urban PM2.5 simulations. The model data set was output at hourly intervals, spanning the simulated month.
Scientific Computing Visualisation extracted specific parameters from the dataset, which included fine particle concentrations generated from fires, dust, sea salt, vegetation and anthropogenic sources. Cloud cover was also extracted. Data processing included adjusting thresholds and scales to highlight the important structure in each parameter and display the relative contribution of each source to the total PM2.5. These images were processed in parallel on ASC's GPU supercomputing facility, producing several high-quality visualisations in a short period of time.
For presentation and interactivity of the visualisation, a WebGL application was created. This allowed users to connect and interactively explore the simulated data.
