波候の統計学的特性とその応用について

抄録

This study deals with the statistics of wave climates (hourly H_1/3, for example) which are simulated applying the spectrum modeling method (Kimura and Ota. 2012). Especially, their micro statistical properties such as monthly numbers of days of H_1/3 >< H_* and the run of H_1/3 >< H_* are compared with the observed data (NOWPHAS), where H_* is the threshold wave heights. The statistical properties of the simulated data show good agreements with the observed data. The present model is applied to two examples in the last. One is the definition of the starting date of a year which minimizes a number of high wave days during the construction works. Another is a long-term presumption of non-stationary wave climate during the in service period of the structure due to the global warming, for example.
