How are anomalies calculated?

An anomaly is the difference between an actual value and some long-term average value.

For example, if

X = actual value of average temperature for January, 1982 and
Xbar = long-term average temperature for January (an average over many years)
anom = anomaly value for January, 1982

then

anom = X - Xbar
