Abstract
A long-term wave hindcast system applicable for the wave computations over a 45-year period at an arbitrary location of Tokyo Bay area is reconstructed. Hourly sea wind distributions estimated by making use of an analogy between land-based SDP wind measurement data and coast- and sea-based wind measurement data are given on the coastal sea area and those made by recompiling the NCEP/NCAR reanalysis surface wind product on the open ocean. Wave computation is based on a backward ray tracing model on a nested grid with very high space resolution. Comparison between hindcasts and measurements for wave height over a long period of 10 to 23 years at 5 stations situated inside and outside of Tokyo Bay verified a reasonable performance of the system.
