Simulation of winds in typhoons by a stochastic model

We presented the statistical specifications of the pressure patterns in the typhoons through the analysis by the Schloemer's formula (1954) in the moderate and severe typhoons which had made landfall on the Japanese main islands during the period 1951-1984. Basing on these specifications, we synthesized a stochastic typhoon model, and carried out the simulation of typhoons by the Monte Carlo technique. Further, a series of simulated typhoons was applied to the estimation of the design basic wind speeds at Akashi Channel as an example . A series of simulated annually maximum wind speeds was represented as the double exponential distribution, and the expected wind speeds at this site were estimated as 44, 47, and 50 m/sec for the 50, 100, and 200 year return periods, respectively.
