초록

The urban areas are dramatically expanding in the northern area of Gyeonggi Province. As aresult, there has been a growing interest in identifying effect of the urbanization on temperature changes. The object of this study is to find some areas where temperature changes are strongly inf luenced bythe urbanization in the areas. For this, characteristics of air cooling of 18 sites in the northern area ofGyeonggi Province are compared with those of a rural site (Ganghwa). The nighttime cooling and coolingrate were used as characteristics of air cooling. Ten years of historical weather records from 2003 to 2012were used in this study. In the results, the air temperature at nighttime of Neunggok and Uijeongbu washigher than that of Ganghwa. In addition, the maximum average cooling rate that occurs at sunset in thetwo sites was smaller than that of Ganghwa. It means that anthropogenic heat flux caused by urbanizationaffects characteristics of air cooling in the two sites. Future research on the relationship betweenurbanization and temperature changes in the two sites will be helpful to developing the proactive strategiesto mitigate the effect of temperature changes by urbanization in the northern area of Gyeonggi Province.
