Heat Absorption: Urban areas with extensive concrete and asphalt absorb and retain heat, contributing to elevated temperatures.
Reduced Vegetation: The prevalence of buildings and paved surfaces reduces green spaces and vegetation, which play a crucial role in cooling through shade and evapotranspiration.
Albedo Effect: Dark surfaces, such as asphalt and dark roofs, have a low albedo, absorbing more sunlight and contributing to higher temperatures.
Energy Use: Increased energy consumption from air conditioning and other cooling systems in urban areas further contributes to the urban heat island effect.
Building Density: High-density urban development can trap heat, creating pockets of elevated temperatures, especially in areas with tall buildings.
Limited Natural Ventilation: Urban structures can impede natural ventilation, trapping warm air and reducing airflow that could otherwise dissipate heat.
Human Activities: Human activities, such as transportation and industrial processes, release heat into the urban environment, adding to temperature variations.
Impacts on Health: Elevated temperatures in urban heat islands can have health implications, including heat-related illnesses and increased heat stress for residents.
