Full description

AUS2200 simulation using the Unified Model (UM) to simulate the warmer Coral Sea surface temperatures (SSTs) during the 2022 Brisbane floods. Between late February and early March 2022, Eastern Australia received record breaking rainfall and experienced devastating flooding. Two simulations that aim to assess the impact of warmer than usual sea surface temperatures (SSTs) in the Coral Sea on the extreme rainfall were run. This is the reduced-SST experiment simulation initialised with climatological monthly mean SSTs from ERA5 averaged over 1960-2019 for the region between -10 to -44 latitude and 143 to 160 longitude. This can be compared to a control simulation using the observed SSTs. The simulation period is 22-02-2022 to 07-03-2022. This simulation is run using the UM v12.2, forcing are the ECMWF ERA5 and ERA5-Land reanalysis fields and the Bureau of Meteorology's Atmospheric high-resolution Regional Reanalysis for Australia (BARRA-R v1.0) for soil moisture. The simulation was run continuously, differently from other Brisbane floods simulations included in the collection. Be aware that this introduces soil moisture drifting. The output was post-processed using the ACCESS-MOPPeR tool (doi: zenodo.10346217) following wherever possible the CMIP6 conventions.
