Abstract

A study on the impacts of sea breeze on temperature distribution was carried out in Kuantan, Pahang, which is a tropical coastal regional urban growth center in Malaysia, for three days i.e. 11 to 13 February 2011 during the end of the north-east monsoon. Two temperature and wind speed traverses of about 10 km long were formed perpendicular to the shoreline of Kuantan. Temperature, relative humidity and wind speed data were measured at about 1.5 m above the ground at several points along these traverses. Hourly measurements were taken contineously for about 15 hours starting from 08:00 until 22:00 Malaysian Locat Time (MLT). The result showed that B3 was the station with the earliest onset time of sea breeze i.e. around 12:00 MLT as well as the longest formation of sea breeze i.e. about six hours. The negative sea breeze-air temperature correlations, r, of between - 0.01 and - 0.33 were calculated for both traverses. The range of temperature reduction due to wind speed of the sea breeze magnitude was between 0.2°C to 5.3°C. Positive correlation was observed between air temperature and relative humidity for all stations with the smallest and highest increment of relative humidity of 2.2 and 16 percent were calculated at stations A3 and B3, respectively. In conclusion, the furthest impact of sea breeze on urban thermal environment towards inland of Kuantan was about 10 - 15 km from the coastline of Teluk Cempedak. These findings are deemed important input for the future urban planning of Kuantan, especially the urban infrastructure to provide a comfortable and a conducive thermal environment for the urban dwellers.
