The Definition of the Standard WMO Climate Normal: The Key to Deriving Alternative Climate Normals

The 30-yr climate normal under the stationarity assumption could be interpreted as the true background state, offset by decadal and longer-term tendencies, and further tweaked by interannual variability (e.g., ENSO-related variations) as well as random and systematic errors. [...] for stationary tim...

Description
Summary:The 30-yr climate normal under the stationarity assumption could be interpreted as the true background state, offset by decadal and longer-term tendencies, and further tweaked by interannual variability (e.g., ENSO-related variations) as well as random and systematic errors. [...] for stationary time series, the standard WMO climate normal is a reasonable metric with respect to both of its primary utilizations.
