摘要:
利用小波分析对贵州省清镇市1958～2003年的逐月平均气温和1979～2003年的逐月降水量进行多时间分辨率分析。结果表明，小波系数图和小波方差图可以清楚的显示气候变化在不同时间尺度上的演变特征，并能够对未来气候演变的趋势做出定性的判断。
Abstract:
Wavelet transformation is used to analyze monthly mean temperature from the year 1958 to 2003 and the monthly precipitation from the year 1979 to 2003 in Qingzhen town, in order to get the information of the multi-timescale climatic change.The results show that the wavelet coefficients and wavelet variances can reveal the characteristics of the climate variation on different time scales.In addition, it can also used to estimate qualitatively the future tendency of climate.
