One-point correlation maps for four points (in rows) for low (left) and high (right) solar activity. The geographical coordinates of the points are provided together with the congruence coefficient (multiplied by 100) between the two maps. Contour interval is 0.2, negative contours are dashed, zero contour is omitted. Negative values below −0.3, which are later used for the definition of teleconnected area, are shaded. Red dot indicates the base point; red cross indicates the point with most negative correlation, used for the definition of teleconnectivity.
