(a) Temporal variability in drought and storm activity in relation to forest disturbance activity across temperate forests of Europe. Storm years are years with mean daily maximum wind speed >0.5 standard deviations above the long-term average. Low SPEI values indicate drought periods. (b) Relationship between annual drought (lag of 3 years and smoothing of 3 years) and changes in forest disturbance area as estimated from the GLS model. (c) Relationship between annual peak wind speeds (lag of 3 years and smoothing of 3 years) and changes in forest disturbance area as estimated from the GLS model
