Urban climate

Urban climate refers to climatic conditions in an urban area that differ from neighboring rural areas and are attributable to urban development. Urbanization tremendously changes the form of the landscape and also produces changes in an area's air.

Rainfall

Cities absorb much less water per square metre than rural areas, as much of them is paved or built on. In some areas this creates a need for specific measures to reduce the risk of localised flooding during periods of heavy rainfall. Measures include the use of rainwater storage and drainage systems. In some areas this may involve storm sewers to collect rainwater separately from household blackwater, to reduce the risk of polluted water overflowing during periods of rainfall heavy enough to overwhelm sewers.
