| Abstract: | Complex networks have been studied across many fields of science
in recent years. In this paper, we give a brief introduction of
networks, then follow the original works by Tsonis et al
(2004, 2006) starting with data of the surface temperature from 160
Chinese weather observations to investigate the topology of
Chinese climate networks. Results show that the Chinese climate network
exhibits a characteristic of regular, almost fully connected
networks, which means that most nodes in this case have the same number
of links, and so-called super nodes with a very large number of
links do not exist there. In other words, though former results show
that nodes in the extratropical region provide a property of
scale-free networks, they still have other different local fine
structures inside. We also detect the community of the Chinese
climate network by using a Bayesian technique; the effective number
of communities of the Chinese climate network is about four in this
network. More importantly, this technique approaches results in
divisions which have connections with physics and dynamics; the
division into communities may highlight the aspects of the dynamics
of climate variability. |
