The urban heat island (UHI) is a metropolitan area with a relatively higher temperature than other surrounding rural areas. This relatively flat megalopolis is home to more than ten million people, half of whom reside in the national capital area of ​​Seoul. The city's density remains high at 17,288 people per square mile. With the climate bordering between humid subtropical and humid continental, metropolitan infrastructure and human activities make the city more susceptible to climate change and the UHI effect. The city is of specific interest as it is my hometown, and I believe this topic is worthy of investigation since South Korea's urbanization rate ranks sixth among Asian nations, and due to such rapid urbanization , environmental problems have emerged. Since Seoul is an inland city, the intensity of UHI is high, and biodiversity and the population face harmful threats and disruptions due to rising temperatures and the formation of heat waves. Research found that the strongest annual maximum UHI intensity in Seoul is 3.34'C. In this research, the Urban Heat Island effect in Seoul, South Korea will be evaluated at three distinct locations within the city; Chung Gye Chun, an artificial river, already known for improving the air quality and lowering the temperature of nearby areas, Hannam Village The Hill, a residential place with plenty of roadside trees, bushes, artificial waterfalls and grass with buildings 3 to 6 floors surround the area, and Myeong Dong, one of the busiest areas of Seoul, with buildings with a high level of human concentration. Using both raw data and published resources in this field, this paper will evaluate the correlation between inf...... middle of paper ...... and roofs absorb solar energy, thus heating the surface of an urban environment. city, intensifying the UHI. The Berkeley Heat Island Team concluded that lighter asphalts, or "cool pavements," reflect 30 to 50 percent of sunlight, significantly higher than the 5 percent of new asphalt and the 10 to 20 percent of aged asphalt. . cool roofs decrease the temperature inside and outside the building. Such "cool technologies" also seem applicable to Seoul, in the continuous renewal and development of infrastructure. Government programs to reduce energy consumption, initiate plans to increase the efficiency of special areas, limit car circulation, encourage bicycle use, create urban forests and gardens, rooftop vegetation and more. There are also methods of planning wind routes, Blue Way, planning infrastructure, to allow the wind to flow quickly to decrease the heat.
