一维气温时间序列的多重分形研究
STUDY ON MULTIFRACTAL OF 1-D TEMPERATURE TIME SERIES
-
摘要: 采用武汉1951-1970年日平均气温序列作多重分形分析,从计算q阶分数维Dq着手,得到了多重分形谱ƒ(α)曲线,反映了大气运动确实是一个层次分明的过程,具有多标度结构。Abstract: Study is made of multi fractal of 1951-1970 daily mean temperature series from Wuhan.A spectral curve of multifravtal ƒ(α) is obtained based on the calculations of q-order fractal Dq .This indicates that atmospheric motion is really well-divided process,marked by a multiple-scale structure.
