Applied Wavelet Analysis of Indian Monsoons
Azad, Sarita The main aim of the present work is to search for periodicities in the monsoon rainfall data. A new method that combines multi-resolution analysis (MRA) and classical Fourier spectral methods to identify peaks in the power spectral density of a given time series is proposed. The method is validated on specially designed test signals. The proposed method is then applied to the rainfall time series, especially to help separate closely spaced per...
