Initialization, Prediction and Diagnosis of the Rapid Intensification of Tropical Cyclones Using the Australian Community Climate and Earth System Simulator, ACCESS
Abstract
The Bureau of Meteorology has recently shifted to using ACCESS (the Australian Community Climate and Earth Simulation System), which is based around the assimilation and prediction systems from the U.K. MetOffice, as its numerical weather prediction system for operations and research. A re-locatable run-on-demand version specifically for tropical cyclones (ACCESS-TC) has been developed and is presently in transition to operations, where it will join the already operational global, regional, tropical and mesoscale versions. The goals for ACCESS-TC are to: (i) support operational TC forecasting in the Australian region, (ii) support tropical cyclone research within Australia, and (iii) support operational TC forecasting in neighbouring states such as Fiji and the Philippines. ACCESS-TC features a state-of-the science atmospheric model, several options for vortex specification, and is one of the very few tropical cyclone NWP systems worldwide to utilize 4D-Var assimilation.
