Indicating the Disaster Area from the maximum wind speed of the Tropical Cyclone in Thailand Using Asymmetric Wind Model

Abstract

The purpose of this research is to approximate the maximum wind speed and simulate a tropical cyclone using asymmetric wind model. The direction of rotation and motion are investigated together in this model.  The observed data of typhoon GAY is selected as a case study in this research because it is the only tropical cyclone with typhoon intensity that moved across Thailand in 1989. Results from the experiment show that the wind speed of part of storm which has rotation identical direction with the movement of the storm is greater than the others. The maximum wind speed can cause the most severe damage to life and properties. In addition, the MATLAB programming is also used to indicate the wind speed contour for observing the disaster area from the maximum wind speed of the storm.
