The Atmosphere in some respects acts quite randomly. However, this “randomness” obeys certain laws. This figure shows the spatial distribution of a random walk scaling exponent for the Northern Hemisphere 500 mb height field. Contoured values greater then 50 indicate the tendency for anomalies to be persistent independent of the time scale

2

Total number of links (connections) at each geographic location. The uniformity observed in the tropics indicates that each node possesses the same number of connections. This is not the case in the extratropics where certain nodes possess more links than the rest. For details on how this figure was produced please read “What do networks have to do with climate?”
