Several complex dynamical systems are embedded in geographical space. Geographical data have proven its importance in several domains. For instance, the formation and scrutiny of climate networks have emerged as a new research topic in environmental literature. However, there is still a lack of investigations of scenarios with very high spatial resolution, such as those considering meteorological data. Recently, a new concept, named (geo)graphs, was proposed. (Geo)graphs are graphs, or networks, in which the nodes have an assigned geographical location. Besides embedding nodes into space, these graphs are readily manipulated with a geographical information system, and, thus, represent a suitable tool for dealing with very high-resolution scenarios, such as meteorological data. In this context, here, we apply a (geo)graph approach to model a radar-derived rainfall data set. We represent the nodes as …
