Country-Level Cyclone Intensity Index for 128 Territories, 1970-2014

128 countries and territories have a non-zero Cyclone Activity Intensity Index (IIC) calculated from 3,915 events recorded between 1970 and 2014. The index, developed by Issakha Thiam, incorporates wind speed, duration, and the proportion of a country's territory affected, moving beyond the Saffir-Simpson scale. Primary data is sourced from NOAA's International Best Track Archive for Climate Stewardship (IBTrACS) v03r07.

Use Cases

• Modeling climate change impacts on cyclone intensity based on the multi-parameter IIC index.
• Assessing country-level vulnerability to cyclones based on wind speed, duration, and territorial exposure.
• Comparing regional cyclone activity evolution using the 44-year historical record.
• Validating climate predictions against observed cyclone intensity trends at a national scale.

Strengths

• Index calculated for 128 countries and territories, providing broad geographic coverage.
• Based on 3,915 cyclone events from a 44-year period (1970-2014).
• Uses a multi-parameter index (wind speed, duration, affected territory) derived from the authoritative NOAA IBTrACS source.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data ends in 2014; freshness should be verified for contemporary analysis.
• Row count is unknown, which may limit suitability assessment.
