| 摘 要： | 一个气候时间序列含有多个时间尺度 ,形成不同尺度的气候层次。气候是冷还是暖是随着尺度而变化的。文中用北半球地表月平均气温气候资料的子波变换分析表明 :气候突变点既随尺度有规律的变化 ,也具有随尺度变化而不变的性质 ,即标度不变性。不论什么尺度 ,气候总是有冷暖之分 ,这种自相似性可以帮助笔者从气候资料的子波变换中建立一个一维映射动力系统 ,它反映出气候突变时间的演变规律和气候的层次结构。

| Abstract: | A climatic time series consists of many time scales, the climatic hierarchy ofdifferent scales can be constructed. Whether colding or warming climate will depend time scales. It is shown that the numbers of climatic jump point are approximately according to Fibonacci sequssces with scale hicrarchy. There exists a scaling invariance. Because the colding and warming hierarchical structure of climate records is self similar, then a dynamical system which leaves climatic scaling invariance can be uncovered from the time scale arrangement of its wavelet transform extrma. The dynamical system denots evolutional laws of climatic jump time and hierarchical structure of climatic series. |
