Urban heat island (UHI) is a metropolitan area with relatively higher temperature compared to other surrounding rural areas. This relatively flat megacity is home to more than ten million residents, half of whom reside in the National Capital Region of Seoul. The city's density remains high with 17,288 inhabitants per square kilometer. With a climate on the border between humid subtropical and humid continental, metropolitan infrastructure and human activities make the city more susceptible to climate change as well as the UHI effect. The city is of particular interest because it is my hometown, and I think this topic is worth studying because South Korea's urbanization rate ranks 6th among Asian countries and because of this rapid urbanization, environmental problems appeared. As Seoul is an inland city, the intensity of UHI is great, and both biodiversity and population face threats and adverse disturbances from increasing temperature and to the formation of heat waves. The research found that the annual maximum intensity of UHI is strongest in Seoul, at 3.34°C. In this research, the urban heat island effect in Seoul, South Korea, will be evaluated at three distinct locations in the city; Chung Gye Chun, a man-made river, already known for improving air quality and lowering the temperature of nearby areas, Hannam Village The Hill, a residential neighborhood with an abundance of roadside trees, bushes, artificial waterfalls and grass with 3-6 story buildings. surround the area, and Myeong Dong, one of the most populated areas of Seoul, with buildings with high levels of human concentration. Using both raw data and published resources in this field, this trial will evaluate the correlation between inf...... middle of paper ......ts and roofs absorb energy from the sun, thus warming the surface of an urban environment. city, intensifying the UHI. The Berkeley Heat Island team concluded that lighter asphalts, or "cold pavements," reflected up to 30 to 50 percent of sunlight, which is significantly higher than asphalt's 5 percent new and 10 to 20 percent of aged asphalt, and “Cool roofs lower the temperature inside and outside the building. Such “cool technologies” also seem applicable in Seoul, in the context of infrastructure renewal and development. Government programs to reduce energy consumption, launch plans to increase the efficiency of special zones, limit automobile traffic, encourage the use of bicycles, create urban forests and gardens, green spaces on roofs, etc. There are also methods of planning wind routes, the Blue Way, by planning infrastructure, to let the wind in quickly and reduce the heat..
