| Abstract |
The temperatures in city centers have been increasing in recent years. Artificial .areas in cities are increasing as urban development intensifies. This phenomenon is happening in medium-size cities as well as in big cities. To analyze this phenomenon, I carried research activities in Asan City. Field measurement points were selected in downtown areas and residential areas. I carried out both continuous measurements and instantaneous measurements. The continuous measurement points were in the downtown area((1),(2),(3)) and residential area((4),(5)). Temperature and humidity were recorded over days (Autumn season: 2008.10.16∼2008.10.18; Winter season: 2009.02.16∼2009.02.18). The instantaneous measurement points were selected at a crossroad, a small park, and near a water space in the downtown area and were measured during 4 time zones. I analyzed the continuous measurement data and instantaneous measurement data in conjunction with data from the Korea meteorological Administration (K.M.A.) near by Asan City. The results of the study are as follows. The order of temperature at the continuous measurement points in Autumn was (1) > (2) > (3) > (5) > (4) > K.M.A.. The order in Winter was (1) > (3) > (2) > (5) > (4)and K.M.A.. The instantaneous measurement temperature at peak time was recorded in the following order : the crossroad > the small park > around the water space. |
