Detailed explanation-1: -Structures such as buildings, roads, and other infrastructure absorb and re-emit the sun’s heat more than natural landscapes such as forests and water bodies. Urban areas, where these structures are highly concentrated and greenery is limited, become “islands” of higher temperatures relative to outlying areas.
Detailed explanation-2: -(WMC)-In cities, the air, surface and soil temperatures are almost always warmer than in rural areas. This effect is known as the Urban Heat Island (UHI). Urban areas, where these structures are highly concentrated and greenery is limited, become “islands” of higher temperatures relative to outlying areas.
Detailed explanation-3: -Cities often suffer from ‘heat islands’, the phenomenon of temperatures being higher within cities than in neighbouring rural zones. This amplifies the effect of heatwaves in cities and increases the risk to human health.
Detailed explanation-4: -Urban areas can sometimes have temperatures up to 15 degrees warmer than nearby rural spots. In the summertime, this is known as urban heat island effect. Cities are filled with more pavement and buildings, while rural areas have more greenery. The difference in albedo leads to a difference in temperature.
