%X Motivated by the serious impact of negative orography on climatic simulation in spectral models, the orography presentation has been renewed in the global climate model IAP/LASG GOALS. Based on comparison between results from old and new orographic experiments, it is revealed that the originally systemic deviation of modeling on the Western Pacific Subtropical High is related to the negative orography at 30 o N, 120 o E and along the latitude to its east. By comparing these model results with the reanalysis data of NCEP/NCAR and CMAP, it can be concluded that the effects of negative orography can be suppressed to a great deal under the new orography scheme, and therefore the simulation of East Asia subtropical climate can be distinctly improved.
