TOPOGRAPHICAL CHARACTERIZATION OF PARAMETER VALUE IN BOX-COX TRANSFORM FOR DAILY MAXIMUM WIND SPEED

Abstract

 The Box-Cox transform is used for the analyses on weather risks having non-normal processes. For the lack of information on the parameter value in the Box-Cox transform, the data on the parameter values for a variety of weather factors need to be collected and compiled . In this study, a dataset of parameter values in the Box-Cox transform for daily maximum wind speeds is presented for the convenience of strong-wind risk estimations, in which the time histories of daily maximum wind speed observed at meteorological stations in 116 regions are used. The relationship between the parameter value and the topography of each region is discussed, and the parameter values are classified into 8 groups in accordance with the topographical features.
