기온변화 번역(영어 번역본)Introduction With the emergence of global warming and climate change as worldwide issues of concern, urban climate change also has become the subject of increasing attention. Urban climate refers to the microclimatic conditions created by the changes in water balance due to changes in land usage, changes in radiation and energy balance, and changes in the wind field, all of which urbanization entails. In particular, there has been a growing interest in developing methods to respond to the urban heat island (UHI) effect, or the rise in temperature near the center of cities. The majority of the methods so far proposed for reducing the urban heat island effect involve reducing energy consumption and heat production. But there is also a need for more scientific research to propose effective solutions reduce the UHI effect by regulating radiation and energy balance through changing the covering material of urban structures. In addition, since Steven Chu’s claim that painting all roofs white and roads in pale colors would have an effect equivalent to taking all cars in the world off the road for 11 years, there has been much interest in scientifically investigating the applicability of white roof systems in Korean climate. Changing the color of roofs to white or other lighter colors would raise the albedo and decrease the amount of radiant energy absorbed by roof surface, which in turn would lead to reduction of the UHI effect. In addition, changing the roof color in certain areas would influence ventilation by altering the amounts of absorbed and reflected solar energy, which would ultimately have an impact on outside air temperature. In this context, the present study aims to estimate the effect that white roof has on urban climate under Korean climatic conditions. Toward this end, the increase in albedo caused by the whitening of roofs will first be predicted. Then, the net radiation and the sensible heat influx of a sample area will be quantified, which will be used together with the albedo to estimate the change in urban temperature. Scope of study This study used the following data, models, and methods. First, a survey of the buildings in the sample area was conducted using GIS building database and aerial photographs. The roofs in this area were categorized according to their colors, and a database for roof surface area by color was created. Second, previous studies were referred to in order to analyze the increase in albedo that the change in roof color would produce. Third, the KICT Surface Model , which is a heat energy distribution model, was used to calculate the optimum parameter, based on the solar irradition measurements made by the Korea Meteorological Administration. Fourth, models were used to assess the reduction in the seasonal and the hourly heat absorption rate and produce statistical averages. Fifth, the reduction in heat energy was quantified using the distribution model, and the resulting change in urban temperature was estimated. Among the 25 districts of Seoul, the Gangseo District was selected for area under study, as it includes roads, open space, parks, residential areas, commercial areas, industrial areas, and forests, in addition to having an appropriate balance in land usage, dwelling types, and building types. |
