自相关对气候网络拓扑结构的影响
Influence of autocorrelation on the topology of the climate network
摘要：
对气候网络中的联系的不同定义可能导致相当不同的网络拓扑结构。我们使用两种常用的链接定义，从全球不同地理位置的表层大气温度的气候记录构建了一个网络。利用去趋势波动分析，洗牌替代品和海洋和大陆记录的分离分析，我们发现，气候网络的结构的主要影响之一是由于记录的自相关性，这可能会引入虚假的链接。这也许可以解释为什么不同的方法可能导致不同的气候网络拓扑结构。
英文摘要：
Different definitions of links in climate networks may lead to considerably different network topologies. We construct a network from climate records of surface level atmospheric temperature in different geographical sites around the globe using two commonly used definitions of links. Utilizing detrended fluctuation analysis, shuffled surrogates and separation analysis of maritime and continental records, we find that one of the major influences on the structure of climate networks is due to the auto-correlation in the records, that may introduce spurious links. This may explain why different methods could lead to different climate network topologies.
