Anomalies in the top and middle panels are departures from the 1991-2020 base period means and are normalized by the mean annual standard deviation. Anomalies in the bottom panel are departures from the 1991-2020 base period means. Individual monthly values are indicated by "x"s in the top and bottom panels.
