The extra-tropical lifecycle of the storm was almost one week and its predicted path and intensity were poorly handled by all operational models except the US MRF model, which forecast a weak low to move over the northern New South Wales coast.
In this study, there are two aims. The first aim is to perform a synoptic analysis of the lifecycle of the storm from its beginnings as a weak low in the Tasman Sea, to its landfall and eventual dissipation over land. The second aim is to use all available data, augmented by high resolution research data, to carry out a series of numerical experiments on its track and structure.
It was found that using high resolution data and data assimilation plus initialisation, the tracks, intensity and rainfall were well predicted. In particular, landfall was predicted up to four days ahead. Our conclusion concerning the classification of the system is that it should be a named storm.
