The surface climate within a city is obviously different from the climate of its surrounding
suburbs (Oke, 1987). This unique local city climate is called urban climate and is generally
characterized by higher surface air temperature, weaker mean wind speed, and lower relative
humidity compared with the suburbs and countrysides (Landsberg, 1981; Oke, 1987). The
phenomenon in which urban climates exhibit relatively higher temperatures is called the urban
heat island (UHI) effect.
