Annual and seasonal trends in the number of events exceeding P9915min, P991h, and P991d intensity thresholds using Poisson regression. Regression slopes are normalized over the mean value of each variable and expressed as a percent change per year. Significant trends are underlined and bolded, with asterisks indicating the level of significance: * p ≤ 0.05; ** p ≤ 0.01; *** p ≤ 0.001.
