Abstract

The purpose of this study is to analyze the urban heat island ultimately by analyzing long-wave radiation which is the dominant factor of night minimum temperature formation. We observed during two months with four elements which is long and short wave radiation, temperature, relative humidity. And we analyzed the correlation between the four factors of long-wave radiation, temperature, cloud form, and cloud amount during the summer two months on the night time. Observations were carried out at two sites in Daegu and nearby. The results are as follows. ① Long-wave radiation change per 1°C in summer was larger than winter. ② Long-wave radiation amount is affected by temperature change when the amount of cloud is small. ③ Low cloud was analyzed to have more influence on long-wave radiation than high cloud.
