Human activity in producing the urban heat island in Beijing
The temperature of urban areas can be significantly higher than that of the surrounding rural areas. This fact is known as the "Urban Heat Island" effect.
"Urban Heat Island" effect
UHI effect- CAUSES
concrete and man made surfaces
Less water in the soil and environment
Excess energy from buildings
UHI effect- effects
extreme weather and climatic events such as storms, hurricanes, and floods
Increased air pollution and greenhouse gas emissions
human health ( heat strokes etc. )
UHI effect- BEIJING
high levels of air pollution mainly due to coal consumption (coal consumption 30% above average during heating season)
soil erosion in in-land areas due to overgrazing and deforestation causes clay particles to loosen and be blown into the city
high levels of carbon monoxide due to slow driving motorized vehicles
air pollution
Due to the UHI effect air pollution is brought into the city
