Urban heat island (UHI) : The phenomenon in which temperatures in a city are significantly higher than those in the outer suburbs as cities rapidly expand in size. On meteorological near-surface isotherms, large areas of the countryside show little change in temperature, like a calm sea, while urban areas show a distinct zone of high temperature, like an island juting out of the sea. Because these islands represent hot urban areas, they are figuratively called urban heat islands .
