Storm and flood data (Deliverable D6.1)

This deliverable describes the datasets of areas affected by strong tropical cyclone winds and flooded areas made accessible through the ISIMIP data repository. These datasets are derived from state-of-the-art climate, tropical cyclone, hydrological, and hydrodynamic model simulations, respectively, prepared in the context of CMIP6 and ISIMIP3. They describe the annual maximum storm intensity (in terms of wind speed) and flooded area fraction, respectively, in each grid cell globally, under historical and future climatic conditions according to different scenarios of greenhouse gas concentrations. The data can be used for assessing the risks associated with these two hazards, such as risks to life, livelihoods, health, or economic assets. In the context of TipESM, they support the assessment of potential tipping dynamics in household recovery from climate-induced shocks and related poverty risks, as well as flood-induced human displacement risk.
