| 摘 要： | 本文从分析亚洲500毫巴候平均环流得到的前五项自然正交函数的时间系数出发,利用互谱分析方法,研究了候平均环流演变与我国大范围候平均温度的关系在频率域上的特征,得到了凝聚函数显著的主要频带;初步探讨了这种关系的时空结构。这对于深入认识长期天气过程和以环流演变为因子的候平均温度的预报提供了依据和途径。

| Abstract: | The time coefficients of the first 5 EOF's terms are obtained from the analysis of the 5-day mean circulation at the 500-mb level over Asia for the period of 1964-1973. By using the cross-spectral analysis method, the features of the relation in the frequency region between the 5-day mean circulation at the 500-mb level and the 5-day mean surface air temperature in our country are studied. And the main frequency bands in which the coherence function is significant in statistic meaning, are found. On this basis the paper goes further into the time-space structure showing these relations. The results may provide a new fundamental and a new way for researching long-range weather proccesses and forecasting the 5-day mean surface air temperature with the circulation factors. |
