| 摘 要： | 该文简要地分析了水平侧边界嵌套技术中存在的问题，提出了“三维嵌套”的设想，并就不同范围对水平侧边界嵌套及三维嵌套方案进行了对比试验。试验结果表明：（１）三维嵌套方案对区域模式的降水及中、下层形势场的预报均有所改进；（２）嵌套区域越小，三维嵌套方案对预报的改进效果越明显；（３）三维嵌套方案对预报的改进随积分时间的增长而愈加显著

| Abstract: | In this paper,some problems existing in horizontal lateral boundary nesting are analysed and a tentative idea for 3-dimension nesting is proposed. Some experiments have been done for different regions and different nesting schemes. The results show that (1) the precipitation and lower/middle level situation forecast made by fine mesh model are obviously improved,as 3-dimension nesting is used;(2) the smaller the forecast region is the more effectively the forecast improved;(3) the improvement made by using 3-dimension nesting is more marked along with the integration time prolonging. |
