Abstract
For the numerical analysis and initialization in the ASIA Region, a comparative study was made of the stream line, vorticity and vertical velocity patterns according as analysed by a quasi-geostrophic, a linearized balance and a generalized balance, models with 300km coarse mesh and 150km fine mesh, respectively, As a results, it seems that in 300km coarse mesh the analysed pattern by a generalized balance model corresponds better to the synoptic situations of the observed pattern than those of the other two models, and in 150km fine mesh the analysed pattern by a linearized balance model represents better the observed pattern involving medium scale disturbances than those of the other two models.
