add_climatology

The climatology is the average over years (and members for ensemble forecases),
taken separately for each month, season, and coordinate.
By default, the average is taken over all years in the data table,
but you can change this using the years-argument.
By default, climatologies (averages) are calculated for each column that is not
recognized as dimension variable and does not contain characters.

Provides tools for processing and evaluating seasonal weather forecasts,
with an emphasis on tercile forecasts. We follow the World Meteorological Organization's
"Guidance on Verification of Operational Seasonal Climate Forecasts",
