Abstract

Urban areas consist of different land uses which result in various natural and man-made surfaces. These surfaces modify the materials, structure and the energy-balance of the urban environment and the composition of the urban atmosphere. This article analyses the differences in temperature and relative humidity of various land uses in the humid tropical urban climate of Kuala Lumpur. Data were measured at different source points within Kuala Lumpur area during the day (1100 and 1400 hr) and at night (2200 and 2300 hr). Temperature traverses were then drawn across different types of land uses. The results show that the temperature andrelative humidity varied according to land uses. The minimum (28.1 °C) and maximum (33.1°C) temperatures were recorded within the green and built-up areas respectively. The UHIIs for the daytime and nocturnal were calculated at 9.3°C and 9.7°C, respectively. The calculated average UHII for the study area was 9.5°C. In conclusion, the interplay between vegetation coverage and urban impervious surfaces in the context of different land uses led to the variation in surface temperatures and relative humidity in humid tropical urban areas. It is suggested that more green areas, gardens, water bodies or open spaces are provided for Kuala Lumpur to enhance thermal comfort for the dwellers.
