%X There are two singularities in atmospheric governing equations under spherical coordinate system,and hence,velocity at the north and south poles can not be defined and predicted directly by grid-point atmospheric model. To solve this problem,a simple approach is presented,and an explicit square conservation scheme in A-grid for shallow water model is chosen as an example. The new approach defines pole velocity and sets up a difference equation. The new model can predict pole velocity directly,and the numeri...
