HKDSE Geography/M7/Heat Island Effect
< HKDSE Geography | M7
Urban heat island refers to a higher mean air temperature in urban areas than rural areas. Urban heat effect is intensified in following ways
- Blanket effect from pollutants and water vapour
- Man-made heat from air-conditioners and transportations
- Tall and dense buildings block airflow
- Less vegetation leads to little evapotranspiration
