A Discussion of Pole Treatment in Grid Global Models
球面网格全球模式中极点处理方法的探讨

A detailed discussion of the pole treatment in the grid global models is given in this papor.Six schemes of the pole treatment are proposed and comparative experiments are made. The resultsshow that the 6 schemes can all fairly reproduce the July mean climate features. The scheme with predic-tions of the meteorological elements at the poles and the scheme with no use of those elements devel-oped in this paper both have better simulative results and applicational values.
