天然环境气候因子的谐波分析

Harmonic Analysis of the Climatic Data on Natural Environment

主要针对西沙试验站户外相对湿度全年时观测值的时间序列,作谐波分析。从中分离出若干振幅、周期和位相不同的简谐波,并找出对该时间序列影响最大的简谐波,从而提示西沙户外相对湿度的主要变规律和特征。

Harmonic analysis is applied to the time series data of relative humidity, which measured per hour in Xisha Exposure Site. By analysis of the time series data, various harmonic with different amplitude or period and phase is calculated, and the harmonic which has main influence on the time series data is found out. Then the main characteristic and the rule of the relative humidity of Xisha are discovered.
