Abstract: The dependence of the root-mean-square analysis error of an observed element, its gradient and its Laplacian upon 1) observational density, 2) observational error and 3) spatial correlation of observational error have been ...

Abstract: The parameters of the Barnes objective analysis scheme are often chosen on the basis of a desired frequency response, but they can also be chosen using the criterion of the theoretical root-mean-square interpolation error ...

Abstract: The quality of numerical weather prediction available for the Southern Hemisphere from the FGGE data base has been examined. The Australian Numerical Meteorology Research Centre (ANMRC) spectral prediction model has been ...

Abstract: A five-day data assimilation experiment is described in which linear normal mode initialization is used to suppress the transient gravity waves. The initialization is performed on increments to the model fields resulting ...

Abstract: A new limited-area data assimilation system has been developed in the BMRC for operational use by the Australian Bureau of Meteorology. The system analyzes deviations from a primitive equations model forecast, using ...

Abstract: An attempt has been made to isolate some of the problems likely to be associated with the practical implementation of four-dimensional data assimilation schemes in the Southern Hemisphere. In particular, the requirement ...

Abstract: Experiments have been conducted within the framework of the Australian Bureau of Meteorology's global data assimilation and prediction system to assess the forecast impact of Southern Hemisphere sea level pressure estimates ...

Abstract: Increasing the resolution of satellite soundings of temperature and moisture from 500 to 250 km is found to be beneficial for large-scale numerical weather prediction for the Southern Hemisphere, particularly for winter. ...

Abstract: A data assimilation scheme for the Southern Hemisphere has been incorporated into the ANMRC hemi-insertion frequency of six hours and has been performed with the FGGE data base for the period 17?26 and the model has been ...
