South-eastern Australia covers approximately 14% of Australia land mass,
and is very important for Australia’s community and economy. In this work, the
Weather Research and Forecasting (WRF) regional model was run to simulate the
severe drought that happened and then (partially) recovered in this region from 2000
through 2008. The model used the following physics schemes: WRF Single Moment
5-class microphysics scheme; the Rapid Radiative Transfer Model (RRTM) longwave
radiation scheme; the Dudhia shortwave radiation scheme; Monin-Obukhov surface
layer similarity; Noah land-surface scheme; the Yonsei University boundary layer
scheme and the Kain-Fritsch cumulus physics scheme. The model simulation uses
boundary conditions from the NCEP/NCAR reanalysis with an outer 50km resolution
nest and an inner 10km resolution nest. Both nests used 30 vertical levels spaced
closer together in the planetary boundary layer.
