| 摘 要： | 基于NCAR/NCEP的逐日再分析资料,利用相空间重构方法计算了副高脊线指数的点条件概率密度,并将得到的点条件概率密度及其功率谱与各季风影响因子指标及其对应的功率谱求相关,诊断出了影响副高脊线指数活动的最重要的6个指标因子.诊断分析结果表明,基于点条件概率密度的诊断识别方法能够较好识别具有动力关联的指标因子,该方法可以为判断和选择动力模型因子提供参考依据. |

| Abstract: | Based on the data of NCEP/NCAR and by using the method of phase construction, a conditions probability density of subtropical high ridge line indexes was computed, and correlation between the power spectrums of the conditions probability density and the indexes of monsoon were carried out. The most important indexes of the monsoon were finally diagnosed. The results of the diagnosis indicate that the technique of computing conditions probability density can identify the factors which are dynamically correlated. The method can offer the basis in determining and choosing the dynamic factors. |
| Keywords: | subtropical high ridge line indexes phase construction conditions probability density monsoon indexes |
