MSSA Climate Change Analysis

MSSA Climate Change Analysis

A Multichannel Singular Spectrum Analysis (MSSA) of monthly anomalies in lower tropospheric temperature (1982-2010) using an embedding dimension of 13 months. The embedding dimension establishes a time frame of focus in the analysis of evolving spatio-temporal events, and also indicates that the analysis will be run as an Extended PCA on 13 lagged versions of the same series. In this example, the temporal graph again shows an obvious relationship to El Niño, but instead of a single loading image, this analysis has one for each of the 13 lags (only six are shown). These images are like the frames of a movie loop that show the evolution of the lower tropospheric response to the El Niño/La Niña phenomenon.
