Project Summary

Manchester has an extensive network of 55 fixed air temperature monitoring stations which have been recording hourly temperatures since 2010. Analysis of the measured data has revealed that the Urban Heat Island Intensity (UHII, the actual temperature difference between urban and rural areas) in Manchester is significant, and is comparable to the UHI in London (Levermore & Parkinson, 2015). The nocturnal UHI is particularly pronounced, and on warm summer nights, Manchester city centre temperatures may be up to 8K higher than those in outer rural areas (Levermore & Parkinson, 2015). Future climate change projections (UKCP, 2009) indicate that Manchester will experience warmer day and night-time temperatures year-round, especially in summer, as well as increases in the frequency and intensity of heat waves. These changes in climate will enhance the UHI effect, which in summer will have a negative impact upon the health and well-being of vulnerable populations (e.g. the very young and old), as well as increasing energy use for cooling using air conditioning – resulting in increased anthropogenic heating and carbon dioxide emissions; further enhancing climate warming. Funded by the Manchester Geographical Society, this project will analyse the spatial patterns of UHI development across Greater Manchester.
