摘要
本文分析了滑动平均的数据处理方法对周期分析结果产生的影响。提出了过程变量同号积分的数据处理方法,并对亚洲西风指数序列进行了试验分析。分析结果表明,周期的长短与振幅的大小有密切关系,亚洲逐日西风指数的周期振荡具有明显的季节特征。
In this paper, it was pointed out that the method of sliding average has an effect on results of cycle analises.In order to remove this effect, It was raised that the method of variable with same symbole of data alignment was integrated and Asian westerly index was analysed by means of the method. The results show that cycle closely associated with amplitude and cycle oscillation of Asian daily westerly index exists a seaaon feature obviously.
