In this paper, the long-term trends in surface temperature in several large Asian cities (Seoul, Tokyo, Osaka, Taipei, Manila, Bangkok, and Jakarta) have been analyzed for estimating the effects of urban warming. A new index, E-HII, is proposed: it is the value obtained by subtracting the temperature data of the four grids around the city from the observational temperature data in the city. Osaka shows the largest E-HII, increasing from approximately 2.4 degrees C in 1901 to almost 3 degrees C after 1981. The E-HIIs of Seoul, Tokyo, and Taipei, have increased by 1 degrees C to 2 degrees C. Jakarta and Bangkok exhibited a lower E-HII. E-HIIs of Manila and Bangkok have been increasing rapidly after 1961.
本文分析了亚洲几个大城市（首尔、东京、大阪、台北、马尼拉、曼谷和雅加达）地表温度的长期趋势，以评估城市变暖的影响。提出了一个新的指数，即E-HII：它是通过从城市的观测温度数据中减去城市周围四个网格的温度数据而获得的值。大阪的E-HII最大，从1901年的约2.4摄氏度增加到1981年后的近3摄氏度。首尔、东京和台北的E-HII增加了1摄氏度至2摄氏度。雅加达和曼谷的E-HII较低。马尼拉和曼谷的E-HII自1961年后迅速上升。
