Abstract: | Summary This study presents the results of a preliminary research that was conducted in the city of Eilat, located in an extreme hot
and arid zone on the northern coast of the Red Sea. The purpose was to analyse the characteristics of the local urban heat
island (UHI). Diurnal pre-dawn and early-afternoon measurements were taken in winter and summer weather conditions on three
separate occasions for two consecutive years. The results show the development of a moderate UHI located around the most intensive
area of human activity; the city business centre and dense hotel belt. The UHI is more significant at midday during the summer
period, while early morning inversions in winter have a weakening effect on the UHI intensity. It was found that the topography
and wind regime have a dominant effect on the location and intensity of the UHI, while the sea has a very marginal effect.
Due to the UHI influences on the spatial distribution of the heat stress in the city, it is suggested that further applied
UHI research should be focused on the summer period. |
