¥SEOF1 gives loadings of the linear function of 1008 variables that has maximum variance, subject to an extra constraint which ÔsimplifiesÕ loadings, including forcing some to zero.
¥SEOF2 similarly, except that the linear function also has an orthogonality constraint relative to the first.

¥Much of the white space corresponds to exactly zero loadings.
¥Additional simplicity is Ôpaid forÕ by a loss of variance (17%, 13% of total compared to 23%, 13%)
¥SEOF1 contrasts high and mid-latitudes in Atlantic/Europe sector (North Atlantic Oscillation – NAO)
