Kaupunkilämpötila

Kaupunkilämpötila refers to the phenomenon of higher temperatures in urban areas compared to surrounding rural areas. This effect is known as the urban heat island (UHI) effect. It is caused by several factors, including the heat absorbed and re-emitted by buildings, roads, and other urban infrastructure, as well as waste heat generated by human activities such as transportation and industry. Reduced vegetation cover in cities also contributes, as plants help to cool the environment through evapotranspiration. The UHI effect can lead to increased energy consumption for cooling, elevated air pollution levels, and negative impacts on human health, especially during heatwaves. Mitigation strategies include increasing green spaces, using reflective building materials, and implementing efficient urban planning. The intensity of kaupunkilämpötila varies depending on the size of the city, its geographical location, and the prevailing weather conditions.
