Urban Heat Islands(3)
Anyone from a city center will notice that the temperatures there are usually higher than in the surrounding rural areas. The term ‘urban heat islands’ was coined by researchers to describe this phenomenon. Urban heat islands have been attributed to human activity, and it often develops together with urban growth and densely populated areas. Heating and air conditioning systems, power stations, factories, and road and rail transport all generate excess heat that raises the average temperatures in urban areas.[½Å¼ºÂù ±âÀÚ¿Í ÇÔ²² TOEFL READING Áñ±â±â]2018³â 7¿ù 1ÀÏ
Researchers have found that the magnitude of man-made heat in metropolises is comparable to that of the sun‘s radiation. Indeed, during the winter, some cities actually generate more heat than is provided by the sun. Interestingly, the higher summer nighttime temperatures in cities are directly proportional to the heat generated by human activity. In other words, the more energy that is used to cool buildings, the more heat is generated, which heats up the atmosphere even more.[½Å¼ºÂù ±âÀÚ¿Í ÇÔ²² TOEFL READING Áñ±â±â]2018³â 7¿ù 7ÀÏ
Another reason why urban areas are warmer is the materials people employ in the constructions of cities where tall buildings, asphalt roads, and concrete sidewalks are the prevailing surfaces. Especially due to the dark hues of the buildings and roads, these materials absorb and retain more heat from solar radiation than vegetation and soil do. Although both urban and rural areas cool down after sunset, the concrete and asphalt surfaces in urban areas more gradually radiate their stored heat, which makes urban areas remain hotter.
