Abstract: Modifications are made to an operational numerical weather analysis procedure concerning, chiefly, generation of the first approximation and consistency of analyzed scale with information density, with a view to extending ...

Abstract: A description is given of a primitive equation model designed specifically for extended operational prediction in the Southern Hemisphere. The model closely resembles in dynamical and physical aspects the well-known ...

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: A new movable fine-mesh model (MFM) developed at the Australian Numerical Meteorology Research Centre, for mesoscale data assimilation and forecasting, is described. For the present, it is a 10-layer, hydrostatic, primitive ...

Abstract: The most recent version of the Australian Numerical Meteorology Research Centre limited-area primitive equations model is described in this paper. A staggered grid system has been introduced, the semi-implicit equations ...

Abstract: The Aerosonde is a small robotic aircraft designed for highly flexible and inexpensive operations. Missions are conducted in a completely robotic mode, with the aircraft under the command of a ground controller who monitors ...
