Abstract

The study investigates 50 years' wave simulation in Northern Pacific using the NCEP/NCAR reanalysis surface wind fields. The reanalysis wind fields are applied to the third generation wave model with the grid spacing of 0.5 degree both in latitude and longitude. The numerical results are compared with observed wind and wave data to verify the model performance. The validation gives good agreement with the means, biases, scatters and probability distributions. A long-term trend of wave climate shows statistically significant increase of wave heights and periods at the Northern Pacific Ocean. The extreme wave statistics gives 50 and 100 years extreme wave heights and may contribute a first guess of extreme wave heights in this area.
