Distribution of extreme climatic events
Across the 18 years we identified a total of 2,724 monthly SPEI-03 values, which were classified as normal periods or anomalous climatic events. Outside normal periods, 36% were wet events, among which 20% were extreme and 16% were moderate wet events. The dry events represented 24%, among which 11% were extreme and 13% were moderate dry events (Figure S1).
