Abstract
We numerically simulated wind conditions in a mountainous region during Typhoon 0423 using LAWEPS (Local Area Wind Energy Prediction System), and estimated wind speed at the locations of the AMeDAS and pipe-houses. As a result, the maximum estimated wind speed at the AMeDAS location agreed with the maximum wind speed observed by AMeDAS, and the maximum estimated wind speed at the pipe-house locations corresponded well to the damage rate (ratio of numbers of pipe-houses with damage to numbers of all pipe-houses) calculated for each wind speed scale. We concluded that maximum wind speed at the pipe-house locations could be estimated using LAWEPS. Estimated wind speed can be used to analyze damage factors such as pipe structures, covering films, and site conditions, etc. in investigations of pipe-house damage by strong wind.
