HEAT WAVES CAUSING HEALTH
STRESS IN AUSTRALIA
Climate impact indicators
Global essential climate variables/indicators used
Our essential climate variables are observations and model simulations of daily Maximum and Minimum surface air temperature.
Regional/local indicators used and produced
We are aiming to use regional high-quality observations of daily maximum and minimum temperature to evaluate climate simulations on regional scale.
Global data to regional/local scale
Step 1: Collect of global observations and simulations of daily minimum and maximum temperature from the CDS.
Step 2: Evaluation of global simulations of mean surface air temperature over historical period using the observations
Step 3: Sub-select a group of model simulations that failed the evaluation and will not be used further
Step 4: Apply the methodology used for calculating the Excessive Heat Factor (EHF) to both observations and simulations over the historical period
Step 5: Sub-select the Australian region and check/compare heat wave metrics against the Bureau of Meteorology high-quality observational data set.
Step 6: Using the remaining model simulations, calculate future EHF characteristics under high and low emission scenario.
Step 7: Provide the data/results locally using the visualisation tools from the C3S Global Service provider
