摘要
本文先把全球60多个国家分成8个地区,然后对每一个地区从上世纪40年代末到本世纪初的年平均气温使用主成分分析的方法,试图勾勒出全球各个地区气温变化的主线,并进一步使用非参数统计中的COX STUART方法验证对全球各地区气温变化趋势和强弱的猜想。
This paper first divides sixty countries into eight areas, and use the method of principle component analysis to analyze the temperature from 1950 to 1998 of those countries, trying to make clear the main trenes of temperature floating. Furthermore, the method of nonparametric statistics-COX-Stuart Trends Test is also used to confirm whether the guess of the way global temperature changes is true.
