The European Extreme Events Climate Index (E3CI) is an ensemble of indices aimed at providing information about the areas affected by different types of weather-induced hazards and the severity of such events. Currently, based on the corresponding index developed for North America (Actuaries Climate Index), E3CI includes seven components returning information about main hazards. Each component uses an indicator as a proxy for several hazards. The reference value is computed on 1981-2010 time span while, on a monthly basis, E3CI shows a standardised anomaly with respect to the reference values.
The component returns the anomaly, compared to the 1981-2010 baseline, in the monthly cumulative value of the exceedance of the daily maximum temperature above the “climatological” extreme value (95th percentile for 1981-2010).
The component returns the anomaly, compared to the 1981-2010 baseline, in the monthly cumulative absolute value of exceedance of the daily minimum temperature below the “climatological” extreme value (5th percentile for 1981-2010).
The component is assessed by adopting the widely consolidated Standardised Precipitation Index (SPI), returning information about rainfall deficit over three months compared to the “climatological” cumulative value over 1981-2010.
The component returns the anomaly, compared to the 1981-2010 baseline, in the monthly cumulative value of the daily precipitation above the “climatological” extreme value (95th percentile for 1981-2010).
The component returns the anomaly, compared to the 1981-2010 baseline, in the monthly cumulative value of the Significant Hail Parameter (SHIP) daily values above the reference threshold associated with high occurrence probability of hailstorms.
The component returns the anomaly, compared to the 1981-2010 baseline, in the monthly cumulative value of the daily maximum wind speed above the “climatological” extreme value (95th percentile for 1981-2010).
The component returns the anomaly, compared to the 1981-2010 baseline, in the monthly cumulative value of the Fire Weather Index (FWI) daily values above the reference threshold associated with high occurrence probability of fires.
The E3CI returns the mean value of the seven components into a single index
