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 designed to accept data at any or all time steps. After each analysis a nonlinear normal mode initialization is performed. The initial evaluation of the analysis scheme has used a data insertion frequency of six hours and has been performed with the FGGE data base for the period 17–26 May 1979. Comparison with Australian Bureau of Meteorology operational analyses is presented, together with diagnostic evaluation of detailed aspects of the assimilation scheme.
