Most climate change reports predict that the intensity of cyclonic activity is expected to increase with global warming (i.e. rising average temperatures). On the other hand, cyclonic activity and its evolution are, and will be, different according to regions and countries. In order to take into account the various factors defining cyclone intensity, it is important to measure cyclonic activity with an index that goes beyond the simple cyclone wind speed observed on the Saffir-Simpson scale.
The primary data are provided by the National Oceanic and Atmospheric Administration (NOAA), specifically the National Climatic Data Center – International Best Track Archive for Climate Stewardship (IBTrACS): http://www.ncdc.NOAA.gov/ibtracs/.
We use the “polygon” version v03r07, where every storm is registered for every affected territory through which it passes. This database is published by the UNEP/GRID-Geneva (http://preview.grid.unep.ch/), while IBTrACS initially only provides the path line of the eye of the cyclone.
