摘要：

Hourly means of wind speed time series recorded at two wind stations in central Argentina (one inland and the other coastal) are analyzed by means of the visibility graph method. The degree distribution of both series was calculated along with that of their shuffled. Gaussian- and uniform-distributed surrogates. The original series as well as their surrogates show an apparent exponential degree distribution. The v-k (value-degree) plot of the original wind series indicates that the higher values of the series are not necessarily "hubs" for the series, while that of the surrogates are characterized by a reduced connectivity degree of the higher hubs.
