Title: Features of the heat island in seoul and its surrounding cities
Abstract: This study describes the characteristics of the heat island in Seoul, Korea and its surrounding cities based on automobile observations from June to August in 1982. The highest temperature anomaly region (e.g. urban) had the smallest standard deviation, while the lowest temperature anomaly areas (e.g. suburban, rural) had the largest standard deviations. Wind speed was the main limiting factor of the heat island intensity. The critical wind speed, which destroys the heat island, increased with city size and it was found 10 be 11.1 m s−1 in Seoul. Statistical analyses revealed a close relationship between urban indices, such as surface impermeability and population and the heat island intensity. The maximum heat island intensity increased with urban population, however, and the slope of the regression line increased sharply from 1.46 to 3.43 at the point of around 300,000 inhabitants. There was a similar relationship between population and impermeable surface coverage. A relationship between maximum heat island intensity and ratio (%) of impermeable surface was clearly observed. Therefore, this points to a strong interrelationship between the heat island intensity, population, and impermeable surface coverage.
