¥EOF1 gives loadings of the linear
function of 1008 variables
that has maximum variance.
¥EOF2 similarly, except that the
linear function is constrained
to be uncorrelated
with the first.
¥First principal component (the
first linear function) accounts
for 21% of total variance
in 1008 variables and
contrasts high latitudes with
mid-latitudes (especially Pacific
and E Atlantic/SW Europe) -
Arctic Oscillation.
¥Second mainly contrasts Pacific
and E Atlantic and accounts
for 13% of total variance.
