Abstract Wildfires are part of a complex system formed by climate, vegetation, and human factors. The fire changes the vegetation and soil, destroys buildings, affects the biodiversity, and influences human activities. Recent studies project that we will face more severe wildfires in the next years and that the traditional fire forecasting methods might be ineffective. Given this pessimist scenario and the high complexity involving fire dynamics, we need better models to study global and regional fire activity. In the last decade, complex networks have emerged as a powerful model for the analysis of complex systems. This model permits the quantification of the features and dynamics of the system in different scales. In the context of climate sciences, complex networks have been used to study many climatological phenomena, but not wildfires. Given the potential of this tool and the complexity of global fire dynamics, the goal of this project is to develop network-based methods to quantify the influence of the climate on fire activity. We will focus on temporal climate networks constructed using two approaches: statistical association measures (correlation networks) and causal inference (causal effect networks). In both cases, we will divide the underlying region into grid cells and use nodes to represent them. The major difference is the way how the links between nodes are established. First, we want to quantify the impacts of climatological phenomena, like El-Niño and extreme events, in the network topologies. Then we will search for temporal patterns in the network topologies using graph mining tools. We expect to better understand the relationship between climate and fire. | |
