The history of PAOBs in the Australian Bureau of Meteorology
نویسنده
چکیده
One characteristic of numerical weather prediction (NWP) practice in the Australian Bureau of Meteorology (‘the Bureau’) since the early 1970s that distinguishes it from the practices in many other national meteorological centres has been the ongoing effort to incorporate the skills of manual analysis, including satellite imagery interpretation, into the initial states for NWP. Both the way in which such manually interactive information has been provided, and the way in which it has been used subsequently by numerical analysis and data assimilation systems, have changed over the years. The main purpose of the following is to record an historical overview of this endeavour, with emphasis on its evolution and impacts. We also hope that this account may provide users of the early Australian numerical analyses, in the possibly distant future, with an understanding of the ingredients of those analyses produced under real time operational constraints during the first decades of NWP. Because this paper is intended as an overview for the generalist reader we shall omit much of the technical detail, both about manual synoptic analysis and satellite imagery interpretation, and about numerical analysis and data assimilation systems. However, such detailed aspects are covered by reference where possible. We also provide an Appendix, showing a chronology of major developments in both Australian region and hemispheric/ global analysis at the Bureau. Aust. Met. Mag. 52 (2003) 241-250

One of the parts and parcels of postcolonial literature is to deconstruct the history written by imperialism and to present the one as experienced by the colonized. As victims of British colonialism, Australian Aborigines have always mirrored the historical religious and territorial subjugation of their land in their writings, especially in their dramatic literature because of its high populari...
