Abstract

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.
