【 摘 要 】

Wind Hazard such as a tornado outbreak may lead to a serious threat especially in damaging properties. Tornado is rarely reported in Malaysia which makes the early assumption of 2014 occurrence is due to the cumulonimbus cloud formation process which was further intensified by the wind factors of the monsoons season. This study attempted to determine the spatial correlation between strong winds occurrence in relation to the wind characteristics during the tornado outbreak in Pendang district of Kedah. The GIS process was performed to determine the most likely wind speed and wind direction on that particular date and place which will further enhance the understanding of such phenomena. This study which was carried out based on the data obtained from the Meteorological Department of Malaysia produced a significant discussion that must be considered in future research.
