Seasonal Windstorm Pattern and Damages in Peninsular Malaysia 2018

Abstract

Natural disasters cause damages, losses and social problems. Windstorm has been a major contributor to the losses and damages to the sustainability of human lives and built environment. The formation of seasonality in Southeast Asian countries are affected by the monsoon which brings large scale seasonal interchange of wind pattern. The trend of windstrom events is not properly recorded in any recent or previous studies.This paper analyses the windstorm pattern in Peninsular Malaysia. NCEP FNL Operational Model Global Tropospheric Analyses and Meteorological Operational (MeTOP) datasets were used to retrieve the wind speed and the direction during the study period. Both datasets show approximate value of wind pattern based on reported events. Southeast-monsoon (SM), Northeast-monsoon (NM) and Inter-monsoon (IM) impacts are considered in this study. The result exhibited the highest windstorm event was Southeast-monsoon, and the highest wind speed is from NS that is 5.96 m/s to 6.23 m/s. While the highest wind speed outside of peninsular that blows and impacts the land is from SM and the value calibrates in between 9.20 m/s to 10.96 m/s.
