|
We examined urban heat island intensity in Seongseo, Dae gu, South Korea, where a large area of water is located within
the suburb. We found a maximum urban heat island intensity of 4.2℃, which occurred around 7 PM in the summer season.Throughout the remainder of the year, we observed the largest heat island intensity levels during late night hours. In contrast,the winter season displayed the smallest values for heat island intensity. Our results conflicted with heat island intensity values for cities where suburbs did not contain water areas. Generally, cities with suburbs lacking water displayed the largest heat island intensity levels before sunrise in the winter season. We also observed negative urban heat island intensity levels at midday in all seasons except for the summer, which is also in contrast with studies examining suburbs lacking water areas.
The heat island intensity value observed in this study (4.2℃) was relatively large and fell between the averages for, Asia and Europe according to the relationship between urban population and heat island intensity.
