Maps for solar minimum (left) and solar maximum (middle) of teleconnectivity multiplied by 100 (top row) and normalized teleconnected area (for more details see text; bottom row). Teleconnectivity: contour interval 10, contours start at 50, values over 60 are shaded. Teleconnected area: contours 100, 200, 300, 400, 600, and 800; light and dark shading for values over 200 and 600, respectively. Differences between solar maximum and solar minimum and their statistical significance (right): differences denoted by black contours, dashed for negative values; for teleconnectivity, contour interval is 20, starting from ±10; for teleconnected area, contour interval is 200, starting from ±100; significance at the 10%, 5%, and 1% levels is denoted in turn by a thick coloured contour, light coloured shading, and dark coloured shading; positive and negative differences are shown in red and blue, respectively.
