Abstract:
This thesis develops a task-specific, Gamma-distributed Climate Social Impact Index (CSII) for analyzing the social significance of climatic variations. The CSII is designed to be covarying with human and/or physical environments in both spatial and temporal scales and is best at processing meso-scale climatic variations. Construction of the CSII is based on the Evapotraspiration Heat-Precipitation Index (EHPI) which the current author previously developed. The CSII is validated against climatic and social-demographic records of 15th century France. It was discovered that the CSII processes well the reconstructed temperature and precipitation conditions within 100 years period. But it was also proved that the CSII does demand a large set of imported data in order to function in full capability.
