| Abstract |
This study is concerned with the estimation of extreme wind distribution and of wind speeds for return period in the major cities reflecting the recent meteorological data(uncorrelated samples obtained from largest daily data records(1990-2010), largest yearly data samples(1971-2010)). They were standardized homogeneously to the surface roughness category C, and to 10m above ground surface. This study seeks to ascertain whether the any extreme distribution is an appropriate extreme wind speed model by performing statistical analyses based on the 'peaks over threshold' approach. This study uses the de Haan method, which was found in previous studies to perform about as well or better than the other methods, and has the advantage of providing estimates of confidence bounds. The analyses provide persuasive evidences that extreme wind speeds are described predominantly by reverse Weibull distribution, which unlike the Gumbel distribution has finite upper tails. |
