The Characteristics of Urban Heat Island in Bangkok, Thailand Sigit D. Arifwidodo, Takahiro Tanaka Abstract
2、 The study focuses on the characteristics of urban heat island (UHI) in Bangkok, Thailand. Hourly air temperature data from four weather stations -one in rural site and three in urban sites for the last five year are used to study the characteristics and intensities of UHI in Bangkok area. The resul
3、ts indicate the presence of urban heat island in Bangkok and it is increasing in terms of intensity. The study reveals the maximum intensity of around 6-7C is detected during dry season. The mean annual air temperature in Bangkok city is higher by 0.8C than outside the city. The weather conditions (
4、wind, cloud, and precipitation), and different land cover types are the major factors governing the near surface urban heat island.

A measure to quantify urban heat island usually uses the term Urban Heat Island Intensity (UHII) (Kolokotroni, 2005), which is the maximum temperature difference between urban and rural air. Generally, the largest urban heat island eff
6、ect, or maximum urban-rural area temperature difference occurs most at night, three to five hours after sunset, because the roads and other surfaces absorbing solar radiation in daytime release heat in nighttime. Thus, the rural areas cool off faster than urban areas at night. UHIs can provide both negative and positive impacts for cities. As cities grow, the urbanization causes less tree and vegetation displaced by buildings and roads, more skyscrapers and streets trap the wind path, and m
