Examining the records for daytime temperatures above 37oC between 1961 and 2005 around Taiwan, as Figure 2 illustrates, only one region shows an obvious increase. Significantly, this was the capital Taipei, which went from less than five days per year at 37oC to over 12, indicating that Taipei is a clear candidate for HIE.
其三，再看 1961 年至 2005 年，台灣各地「白天氣溫高於 37℃」的天數變化：圖二顯示，大於 37℃的天數只在台北市明顯增加（從每年低於 5 天增為超過 12 天），顯然是受到都市熱島效應的影響。
