Assessing urban population vulnerability and environmental risks across an urban area during heatwaves - Implications for health protection.

摘要: Heatwaves can lead to a range of adverse impacts including increased risk illness and mortality; the heatwave in August 2003 has been associated with ~70,000 deaths across Europe. Due climate change, heatwaves are likely become more intense, frequent last longer future. A number factors may influence risks heat exposure, such as population age, housing type, location within Urban Heat Island, not be evenly distributed spatially region. We simulated analysed two major UK, July 2006, assess spatial vulnerability exposure West Midlands, an area containing ~5 million people, how ambient temperature varies relation that heat-related health effects, through weighting temperatures according distributions these urban area. Additionally we present quantification particular centres hospitals exposed UHI, by comparing at locations average region, presenting results for both day night times. find UHI intensity was substantial during heatwaves, reaching maximum +9.6°C Birmingham 2006. Previous work shown some types, flats terraced houses, overheating, our show types generally located warmest parts city. Older age groups susceptible effects heat. Our analysis distribution based on group showed there is only small variation different to. Analysis relative deprivation region indicates deprived populations
