摘要
通过截取沈阳市气象站(54342)2013年5月的观测资料进行影响蒸发的主成分分析研究,来确定各气象要素对蒸发的影响比重,结果表明,影响蒸发的主要气象因子为地表温度和相对湿度,其次为风速,风速在影响蒸发中起的作用较小。
Through intercepting the observation data of Shenyang Weather Station （54342） in May 2013, the principal component affecting evaporation were analyzed, to determine occupying proportion of influence factors of evaporation.The results showed that the main meteorological factors that affect the evaporation were the surface temperature and relative humidity,followed by wind speed,so wind speed played the less important role in affecting evaporation.
