摘要
论述了子波气候诊断中的边界效应和非周期性对趋势预报的影响,在消除子波变换边界效应基础上,将气候层次理论和子波诊断技术相结合,提出了气候多层次趋势预报法则和评判标准,最后利用若干气候资料进行了多层次趋势预报。试验表明,相似延伸法能有效地消除边界效应,提出的气候多层次趋势预报法是可行的。
The impact on climatic trend prediction from boundary effect and non-periodicity inwavelet climatic diagnosis is stated in this paper. After decreasing wavelet transformation's boundary effect, the prediction law and assessment standard are put up based on the theory of climatic hierarchy and wavelet analysis. The experiments show that analogue extension may well decrease boundary effect, and that the prediction law is useful.
