Typicality analysis for extreme climate events

Recent studies found that the concept of typicality of extreme events is relevant in case of several weather and climate extremes related to atmospheric circulation anomalies, such as heatwaves or cold spells. This concept refers to the property of extreme events of being similar among each other while being at the same time anomalous with respect to usual weather conditions, referring to both spatial patterns and temporal evolutions. The aim of typicality analysis is to clarify whether this property applies to the extreme events of interest and to quantify the strength of typicality. In this presentation, I will discuss different types of typicality and give a practical guidance on how to perform a typicality analysis using climate datasets. I will present the most important steps of the analysis, discussing also several tools we can use to quantify typicality, such as standard statistical measures, Taylor diagrams, dynamical systems-based indicators.
