Exploring meteorological droughts’ spatial patterns across Europe through complex network theory

Domenico Giaquinto, Warner Marzocchi, and Jürgen Kurths

Abstract. In this paper we investigate the spatial patterns and features of meteorological droughts in Europe using concepts and methods derived from complex network theory. Using Event Synchronization analysis, we uncover robust meteorological drought continental networks based on the co-occurrence of these events at different locations within a season from 1981 to 2020 and compare the results for four accumulation periods of rainfall. Each continental network is then further examined to unveil regional clusters which are characterized in terms of droughts’ geographical propagation and source-sink systems. While introducing new methodologies in general climate networks reconstruction from raw data, our approach brings out key aspects concerning drought spatial dynamics, which could potentially support droughts’ forecast.

Short summary
Despite being among the most severe climate extremes, it is still challenging to assess droughts’ features for specific regions. In this paper we study meteorological droughts in Europe using concepts derived from climate network theory. By exploring the synchronization in droughts occurrences across the continent we unveil regional clusters which are individually examined to identify droughts’ geographical propagation and source-sink systems, which could potentially support droughts’ forecast.
