摘要
本文计算了亚洲500毫巴月平均环流指数的方差谱。结果指出:亚洲经向及纬向环流指数谱的分布是有一定差异的,前者以5个月左右为周期的谐和振动占有显著的地位,而后者则以5个月以上的长周期振动所占的成分较大。
In this paper, the power spectrum of the monthly 500 mb circulation index over Asia has been calculated. The spectrum difference between meridional and latitudinal index is found to be significant. In the spectrum of meridional index there is a significant maximum harmonic component with a period of about five months, and the total variance of the latitudinal index is contributed chiefly by the oscillations with the periods longer than five months.
