%% Effect of Phase Display Threshold on Wavelet Coherence of Weather Data % Compare the effects of using different phase display thresholds on the % wavelet coherence. %% % Plot the wavelet coherence between the El Nino time series and the % All India Average Rainfall Index. The data are sampled monthly. Specify % the sampling interval as 1/12 of a year to display the periods in years. % Use the default phase display threshold of 0.5, which shows phase arrows % only where the coherence is greater than or equal to 0.5. load ninoairdata; wcoherence(nino,air,years(1/12)); %% % Set the phase display threshold to 0.7. The number of phase arrows % decreases. wcoherence(nino,air,years(1/12),'PhaseDisplayThreshold',0.7);
