陆、岛气候的主因子分析

THE PRIMARY FACTORS ANALYSIS OF CLIMATE IN LAND & ISLAND

本文选取了代表连云港市不同地区气候特征的新浦（站2）和西连岛（站1）两站，应用主因予分析的方法对表征两站气候特征的年平均气压、年平均气温、年平均水汽压、年气温最高值、年气温最低值、年总降水量和年平均风速共7个要素进行了分析，分析结果表明：在表征西连岛气候特征的7个要素中，年气温最低值对西连岛气候起主要作用；在表征新浦气候特征的7个要素中，年平均气温对新浦气候起主要作用。在此基础上，我们作两站各气候要素的因予载荷点聚图，从而对各气候要素进行了有意义的分类。

In this paper,the primary factors analysis is used to analyse the seven meteorological elements which represents the climate feature of Xinpu (58044) and Xiliando (58041 ). Theseseven meteorological elements are annual mean preassure,temperature,vapour pressure,themaximum and minimum temperature for years,the total precipitation for years and annualmean wind speeds. It shows that:the minimum temperature for years mostly contributes tothe climate of Xiliandao,while the cimate of Xinpu significantly depends on the annual meantemperature. Based on the results, we classify them practically.
