A grid of eight maps shows daily geopotential heights (meters, contours) and anomalies (colors) at 500 hPa at 05:00 UTC for eight self-organizing map nodes. Nodes 0, 1, 2, 3, 4, and 5 are anticyclonic regime; node 6 is zonal regime; and node 7 is post-trough. Maps are provided by Aifang Zhou, Brookhaven National Laboratory.
