Résumé

We propose an indicator of the intensity of cyclone activity calculated at country level by year. This simple metric uses historical geolocalized data on cyclones, particularly their power and position from which we deduct the affected share of the country area, and their duration. This indicator is calculated (and is nonzero) for 128 countries and territories over 1970–2014. It can be used for cross-country comparison of vulnerability to cyclone activity, which is considered as one of the important consequences of climate change.
