本文对天气预报中采用判别分析所出现的问题进行了分析,并且针对天气预报的特点提出了一种改进方案,我们称之为“离散判别分析”.实践表明:这一方案的预报效果比原始判别分析有一定的提高.它在原理上更为合理,在计算手续上更适合我国广大气象台、站的使用.全文分两部分:第一部分讨论二级的离散判别分析;第二部分讨论多级离散判别分析.
In this paper, we analyze the problems that occur in discriminant analysis in weather forecasting and propose an improved scheme based on the characteristics of weather forecasting, which we call “Discriminant Discriminant Analysis.” Practice shows that the forecasting effect of this scheme is better than the original Discriminant analysis of a certain degree of improvement.It is more reasonable in principle, in terms of calculation procedures is more suitable for the use of China’s vast meteorological stations, stations.This paper is divided into two parts: the first part discusses two discrete Discriminant Analysis; the second part discusses multilevel Discrete Discriminant Analysis.
