The method of wavelet coherency is applied to the ENSO and monsoon indexes. Compo, 1998: A practical guide to wavelet analysis. It uses built-in MATLAB functions to calculate the transform (cwt.m and cwtft.m), the main interest here is how to chose scales/frequency and how to compute cone of influence (COI). Extensions to wavelet analysis such as filtering, the power Hovmöller, cross-wavelet spectra, and coherence are described. This is a MATLAB script Im using to obtain continuous wavelet transform (CWT). New statistical significance tests for wavelet power spectra are developed by deriving theoretical wavelet spectra for white and red noise processes and using these to establish significance levels and confidence intervals. It aims to supply an easy-to-use, portable and efficient wavelet toolbox to those who are used to the matlab wavelet interface. The guide includes a comparison to the windowed Fourier transform, the choice of an appropriate wavelet basis function, edge effects due to finite-length time series, and the relationship between wavelet scale and Fourier frequency. This wavelet library implements the 1D wavelet transform of matlab wavelet toolbox with c++. Torrence & Compo Wavelet Analysis SoftwareĪ practical step-by-step guide to wavelet analysis is given, with examples taken from time series of the El Niño-Southern Oscillation (ENSO).
