STORM climate change tropical cyclone wind speed return periods

Gridded tropical-cyclone wind-hazard datasets giving maximum wind speeds at fixed return periods (and return periods at fixed wind speeds) at ~10 km resolution for each ocean basin, plus companion city/island tables within 100 km; values are derived using Weibull plotting formula from STORM climate-change simulations.

ID of dataset rdls_hzd-nismod_sdk_stormtcwindspeedcc
Publisher of dataset 4TU.ResearchData
Dataset version 4
Data purpose To provide consistent, high-resolution tropical-cyclone wind hazard metrics for present (1979-2014) and near-future (2015-2050) climates that support risk assessment, engineering design, and adaptation planning across basins and selected coastal cities and islands.
Additional details Datasets were generated with the statistical STORM algorithm using IBTrACS as the baseline and adding climate signals from four GCMs (CMCC-CM2-VHR4, CNRM-CM6-1-HR, EC-Earth3P-HR, HadGEM3-GC31-HM); outputs are distributed as netCDF (fixed return periods or fixed wind speeds, by basin) and Excel workbooks (cities/islands) including mean, standard deviation, and 5-95% confidence intervals.
