中文摘要：

气候网络在地球科学领域研究中是一个新的热点，对于分析和揭示气候场的特征及关联结构具有较强优势．已有气候网络的构建一般选取冬季月份的样本数据，而且在研究中忽略了其他季节月份对气候网络的影响．本文研究了季节因素对气候网络的影响，研究发现：气候网络在不同季节的整体特征参数基本保持稳定，但是网络社团结构以及局部节点拓扑连接随季节变化显著．可以利用这一结论来研究不同季节全球遥相关模态变化情况以及局部地区气候特征随季节变化情况．

英文摘要：

Climate network is a new interesting field in the earth sciences. It has advantage in exploring the properties and associated structures of climate fields. In the past researches, only climate dataset for winter month of the years were used to construct climate networks, and the effect of other seasons was ignored. In this paper, how seasonal factors impact on climate networks is investigated. It is find that some of the global properties of climate networks keep stable regardless of season, on the contrary, the community structures of network and local topologies change significantly in different seasons. With this conclusion, the variation of global teleconnection patterns and local area climate in different seasons can be investigated on climate network.
