Heatwave analytics

Make the heatwave data answer a question

Start with a climate question, then switch metric, region, and detail level. The goal is interpretation, not just plotting.

Annual trend Frequency and DFS metrics by year Regional map Hexbin signals by IPCC-style region Event shape HWD, HWMA, and target comparisons Seasonality Monthly top-100 HWMS danger rings

P90 danger threshold

P95 extreme threshold

Between P90 and P95 = very dangerous

Method: for each year and month, events whose detected window overlaps that month are ranked by HWMS. The plotted value is log10 of the top-100 HWMS mean; percentile rings are computed from all non-zero monthly top-100 values.
