Discipline: Geography

Hazard of Interest: Heat

Methods: Principal component analysis, Mapping, Poisson regression analysis, Independent samples test, Skill scores

Key Research Issues: Performance Assessment of a multivariate heat wave vulnerability index (HVI) developed for London, United Kingdom. The HVI is assessed in terms of its ability to predict whether mortality and ambulance callout attain above average levels during heat wave events.

Key Findings: The assessment results reveal that the HVI as well as a simple single variable index that represents age as a heat risk factor (the elderly index) offer potential as a priori indicators of the level of ambulance callout and mortality for all summer days and heat wave events, respectively.
