This presentation will step through the thunderstorm forecast and warning process employed by the Australian Bureau of Meteorology (the Bureau) in chronological order. It is intended as an overview, with most of the emphasis on those practices and systems that are unique to the Bureau.
After some opening remarks on the organizational structure of the Bureau, I will first present a numerical model-based thunderstorm guidance product, the National Thunderstorm Forecast System (NTFGS). The NTFGS is one of the more unique tools that forecasters use in the preparation of convective outlooks.
The warning phase of thunderstorm-related operations can lead to two types of severe thunderstorm warnings. State warnings are issued primarily based on storm environmental information in conjunction with evidence of deep convection. Cell-based metropolitan severe thunderstorm warnings are the result of radar data interrogation and storm environmental analysis. Some of the more unique aspects of this process will be presented, and a demonstration of the radar display software (3D-Rapic) and the warning dissemination software (Thunderstorm Interactive Forecast Preparation System or TIFS) will be given.
