摘要

本文描述了夏季到雨季由于季风的到来而引起的风速的动态变化。基于小波变换的方法识别感兴趣的局部动态。这是通过使用强阈值来实现的，其优点是避免了可能隐藏原始数据中可变性的任意阈值。小波局地极大值法区分了季风到来引起的季节变化。不同季节的能量谱日线图进一步验证了结果，也证实了实质性的变化。

Diagnosing heterogeneous dynamics for wind particle trajectory in wavelet domain

In this paper the dynamical changes of wind speed from summer to rainy season due to arrival of monsoon has been described. Wavelet transform based method identifies local dynamics of interest. This is accomplished using strong thresholding, whose advantage is to avoid the arbitary threshold that might conceal variability in raw data. Wavelet local maxima approach differentiates the seasonal variations due to arrival of monsoon. The results are furthur verified with Energy spectrum vs day plots for different seasons which also confirm the substantial changes.
