全球氣候分區之研究

A Global Climatic Classification Study

摘要


氣候變異對人類生活影響日益嚴重,本文目標是使用主成份因子分析方法分析全球地區1961-1990月平均降水量和月平均氣溫之空間變化,研究結果顯示主成份因子1,2及3分別解釋55%,21%及14%之全球地區月平均降水量和月平均氣溫變異,主成份因子l與月平均降水量和月平均氣溫呈正相關,主成份因子2與月平均降水量呈負相關,主成份因子2與月平均氣溫呈正相關,本文使用群落分析方法研究全球地區月平均降水量和月平均氣溫特性,研究結果顯示有14個主要氣候分區。

We live in a world that is increasingly vulnerable to climatic shocks. The aim of this research is to apply principal components analysis to analyze spatial variations in monthly average precipitation and monthly mean temperature data for the period of 1961-1990. The results show that the principal components 1, 2, and 3 explain 55%, 21%, and 14% of the variance in the monthly average precipitation and monthly mean temperature data. Component 1 is positively correlated with monthly average precipitation and monthly mean temperature. Component 2 is negatively correlated with monthly average precipitation and positively correlated with monthly mean temperature. This research used cluster analysis to generate 14 climatic regions in a global scale.
