【摘要】 建立了优势因子和优势隐含周期的概念,并提出了多因子逐步回归周期分析的新方法.该方法既能增长预报期,又能充分利用物理因子的重要信息,同时在计算过程中还能挑选出起显著作用的优势因子和优势隐含周期,对预报气象要素的变化趋势效果较好,有一定的实用价值,是气象要素预报的一条比较有效的途径.
【Abstract】 A concept of the dominant factor and dominant hidden cycle was posed,and a new method of analysis of stepwise regression cycle of multi-factor was put forward. The method can both lengthen predictive period and make full use of the major information of physical factors. At the same time it can pick out the dominant factor and dominant hidden cycle of the notable effect in calculating process, which has relatively results for forecasting the change tendency of meteorological element. Therefore it has some practical value, being a relatively efficient way for forecasting meteorological element.
【Key words】 meteorological element; stepwise regression; dominant factor; dominant hidden cycle; risk forecast;
