Full description

AUS2200 simulation using the Unified Model (UM) to simulate the East Coast Low event which gave rise to widespread flooding in many areas stretching from southeast Queensland, eastern New South Wales, eastern Victoria, and large areas of northern Tasmania. This simulation (“Tasclim”) is the fifth in a series of AUS2200 experiments that investigate the role of sea-surface temperatures in the development of a subtropical cyclone and widespread east coast Australia heavy rain in early June 2016. The simulation period is 03-07 June 2016. This simulation is run using the UM v12.2, forcing are the ECMWF ERA5 and ERA5-Land reanalysis fields. This simulation replaces the Tasman Sea region with the same climatological sea-surface temperatures as “Climatology” (1980 to 2019, 3 June averages) while using 3 buffer boxes around the edge to smooth the transition. This simulation shows changes to rainfall and other parameters however the subtropical cyclone’s intensification is similar to the “Fixed” case despite that extensive change in SST. This suggested the warmer Coral Sea is more important for the intensification and led to the 6th simulation Corclim. The output was post-processed using the ACCESS-MOPPeR tool v1.1 (doi: 10.5281/zenodo.13841181) following wherever possible the CMIP6 conventions.
