Study on evaluation time in typhoon simulation based on Monte Carlo method

A computer simulation based on the Monte Carlo Method has been developed for predicting extreme wind speeds in regions dominated by typhoons. These methods have become the most frequently used tools in estimating design wind speeds for structures and the long-term risk levels arising from these winds. aper presents refinements of this method, focusing on improvements to the statistical distribution functions describing typhoon characteristics used in the simulation. Two important points are identified. First, the relation between the radius of the maximum wind speed and the central pressure depth can be approximated by index functions. Second, the mean wind speed predicted from the model tends to correspond with the 3 h moving average value of the mean wind speed.
