    Relations of urban heat island and air pollution are analyzed by using SO₂ concentration data (winter season in 1985) from 10 sites of Seoul area and differences of wind speed and air temperature in urban and rural area. Urban heat island is developed when daily mean wind speed at urban site is lower than 1.5 m/sec or in the interval of 3.0~3.5 m/sec. When differences between urban and rural air temperature is greater than the overall average of those differences, SO₂ concentrations of those above-average differences are 1.3~1.8 times higher than those of below-average differences. The trends are shown obviously at north-eastern area of Seoul (Gilum Dong, Ssangmun Dong, Myeonmog Dong).When intensity of Urban Heat Island is weak, SO₂ concentration was reduced in proportion to a rise of wind speed. But SO₂ concentration is on the partial increase in spite of a rise of wind speed when intensity of urban heat island is strong.
