Wavelet Analysis in DMAP V2.1: Interpreting Drought Periodicity
This tutorial shows how to run wavelet analysis on a drought-index time series in DMAP V2.1 and read the resulting charts, so you can identify the dominant periodicity and see how the strength of different cycles changes over time.
What this tutorial covers
Producing the wavelet power spectrum for a drought index, reading the time–frequency charts, and identifying the dominant periodicity and its link to climate oscillations such as ENSO.
