Description
This dataset represents a suite of climate diagnostics for 56 variables relating to the interannual variability of ECMWF ERA5 monthly mean data. Basic fields for each of these variables include a monthly mean climatology and standard deviation, corresponding anomalies spanning 40 or more years of data, empirical orthogonal
functions (EOFs), principal component (PC) time series, percent variance
explained by each EOF, and an estimate of the standard error of the percent
variance explained. Dominant modes of variability include El Nino Southern
Oscillation (ENSO) in sea surface temperature, and the Antarctic Oscillation
(AO) and North Atlantic Oscillation (NAO) in surface pressure. Separate analyses
are performed for the entire globe, northern hemisphere only, and southern hemisphere
only. There is sufficient information to further explore lagged correlations, teleconnections, and more advanced statistical techniques. Preparation and calculation of this dataset is performed by CISL DECS at NCAR.
