Physical geography and urban characteristics influence the urban climate
conditions. Built-up areas, green urban parks, forest reserves, streets and terrain constitute
the climatic interactions within urban areas. These have led to the variation of the urban
climate condition throughout the world. Thus, in studying urban climate, the impacts of
these factors are crucial to be examined. This study aims to examine the effects of six
important factors, namely built-up areas, green covers, terrain elevation, building volume,
surface roughness and land use type, which contribute to the variation of the urban climate
condition within the Kuala Lumpur City. In this study, the effects of the six factors (urban
parameters) towards the air surface temperature variation were statistically tested. Using
the Weather Research and Forecasting (WRF) model and the remote sensing technique,
the data needed for the analyses were extracted. The Geographical Information System
(GIS) was employed as the analysis platform during the study. Based on the Spearman’s
rho and Mann-Whitney U tests, it was identified that the six urban parameters and the air
surface temperature variation are correlated. The further investigation conducted using the
Kruskall-Wallis test has identified that only five of the urban parameters showed significant
effects toward the air surface temperature variation, which are built-up areas, green
covers, terrain elevation, building volume and surface roughness while the land use type
was excluded. The findings of this study are very crucial as a pioneer research to integrate
the urban climatic information in the urban planning decision making in tropical cities like
Kuala Lumpur.... weniger
