The impact of the typhoon to peninsular Malaysia on orographic effects

Remote sensing techniques have been used to study the impacts of the tropical cyclone. In order to figure out the relationship of typhoon with orography effect, precipitation products are acquired from Feng Yun 2D; and Global Digital Elevation Model (GDEM) from ASTER satellite was applied as well. After combining both the precipitation and elevation products of Peninsular Malaysia (PM), rainfall distribution patterns are distinctly affected by the mountains range. Titiwangsa Mountain range is the major mountain range which is able to influence the movement and distribution of the raining clouds. Normally, Titiwangsa Mountains can separate the raining distribution into 2 parts which is east and west side of the PM. Sometimes, rains can happen at both sides simultaneously when allowable weather conditions exist such as during typhoon activity. The other mountains which are higher than two thousands meters in PM are also able to change the rainfall distribution patterns since some raining clouds are lower than this elevation. 2 types of typhoon tail effects are defined by high low pressure system and centrifugal force reaction.
