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: 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: 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. ...
