Climate Hazard Diagnostics - Cyclones

Emmi — version 1.3 (2026-03-27)

Description

This dataset quantifies tropical cyclone intensity, maximum sustained wind speed (m/s), exceedance probability, and asset average annual loss at 0.1° (~11 km) spatial resolution. The dataset has global ocean and coastal coverage for a historical baseline (1980) and the years 2030, 2050, and 2080 under IPCC climate scenarios RCP2.6, RCP4.5, RCP6.0, and RCP8.5.

Usage notes

Spatial coverage is limited to oceans and coastal land surfaces between 40°S and 60°N. The historical baseline represents a modelled pre-acceleration climate state, not actual conditions in 1980. Future years should be interpreted relative to the baseline, not in isolation as absolute hazard levels. Average annual loss is calibrated to present-day conditions (~2025), enabling assessments of current risk to assets alongside change over time. Meaningful differences among climate scenarios typically occur from 2050 onwards. Cyclone probability values are physically correlated with coastal flood probability values from the Climate Hazard Diagnostics - Coastal Floods dataset, so should not be summed when calculating compound risk.

Variables

average_annual_loss_baseline

NoDataNaN

Description

Expected annual damage as a fraction of asset value for the historical baseline (1980). Data is the product of cyclone intensity, cyclone probability, and a damage calibration factor derived from 1990-2024 disaster losses across 27 countries.

Usage notes

Values range from 0 to 1, representing mean annual proportional loss for all building types and materials. Absolute asset-level losses can be calculated by multiplying this variable by an asset's value. Values < 0.001 typically indicate low physical risk exposure and values > 0.05 typically indicate high physical risk exposure. The damage calibration factor is anchored to present-day conditions (~2025), making data suitable for current-day risk screening alongside future scenario comparison. Average annual loss is intended for portfolio-scale analysis rather than precise asset-level loss estimation. This variable is only available for the historical baseline year (1980), with all other years containing null values.
