Abstract

Abstract:

The atmospheric factors are almost interrelated each other，it is very important in atmospheric studies to understand separate effect of some factor，or joint impacts of several factors，which is most significant for what we concerned．Discovering the most dominant factors can guide us to the focus of problem and the key physical mechanisms．This paper presents a review of the factor separation (FS)technique by Stein and Alpert(1993)and the 2k factorial experiment(FM)by Teller and Levin(2008)and theirs fractional approach in atmospheric studies in order to obtain a better understanding of the various mechanisms and particularly the role of their interactions－synergies in atmospheric dynamics．

Key words: effects analysis, factorial experiment, application in atmospheric studies

摘要：

大气中的因子几乎都是相互关联的，在众多的因素中区别出某个因素对研究对象单独的影响效果、或者几个因素对研究对象共同的影响效果在大气研究中十分重要;通过揭露影响研究对象的主要因素可以抓住问题的主要矛盾，有利于认清事物最重要的本质。本文就Stein和Alpert 1993年提出的因子分离方法和Teller和Levin 2008年用在气象分析中的2k析因方法从数学推论到气象应用做了评述，以便更好的应用在各种物理机制的分析和理解上，其中特别要关注的是它们对于交互作用的研究在大气系统中的作用。
