The National Meteorological Analysis Centre, located within the Bureau of Meteorology, took the place of the Southern Hemisphere Analysis Centre. It was one of three World Meteorological Centres operated by the World Meteorological Organization, producing analyses and prognoses of large-scale weather systems to support the forecasting and warning activities of the Bureau's regional forecasting centres and the briefing services provided to major Australian airports. It later underwent a name change, becoming the National Meteorological Centre.
