The symbols “+” and “−” denote anomaly greater and less than zero, respectively.
The symbol “” indicates anomaly of zero percent. “Obs.” denotes observed change.
The cells with superscript symbol “#” are for anomalies significant at the level of 5%.
Each anomaly was placed at the center of the 10-year time slice, for example, 1965–1974, 1966–1975, 1991–2000, obtained based on the NAIM procedure as described in Section 3.2.3.
