| 分析了各嵌套变量的作用和效果,发现采用部分变量嵌套就能取得一定效果,各变量的作用也不完全相同。这样,可以选取作用大、质量好、易处理的变量进行嵌套。并相应地提出了一个边界嵌套处理方案,应用于南海热带气旋数值预报有限区模式(TL10)与全球谱模式(T63)的嵌套过程中。通过数值预报试验,表明采用该嵌套处理方案能够取得良好的效果。 |

| Abstract: |
| The effect of each nested variate in a nested model is analysed.It is found that the forecast could benefit by nesting partial variates,and the effect of each variate is different. So, only the effectual variates should be chosen for boundary nest. According to this approach, a scheme of boundary neat is presented and applyed to the limited area model(TL10) nested with the global spectral model (T63). for forecasting tropical cyclone over the South China Sea.A few numerical prediction tests show that this scheme is reasonable and efficient. |
