Eigenvector spatial patterns for European temperatures have been investigated for seven periods between 1761 and 1969. When the number of observations greatly exceeds the number of stations used in the analysis, the main patterns of anomaly are seen to be stable in time, appearing in the same position in the eigenvalue ranking order in each period. Patterns which are time‐invariant are concluded to have physical significance.
