Abstract: The wave observation data and statistical products are basic and important references to carry out the wave forecast, make ocean climate and hydrological background, and for scientific research and engineering construction. At present, the data used by the wave statistics products in the business are mostly reanalysis data and satellite inversion data, but the actual observation data are less, which cannot reflect the spatial and temporal distribution characteristics of the subtle waves. In recent years, the great growth of wave observation data provides data assurance for making wave statistics products. For this reason, based on the spatial and temporal distribution characteristics of ocean waves in the northwest Pacific Ocean, the main elements of ocean waves were extracted, quality control and statistical analysis were carried out on the ICOADS original data, and wave observation data and wave statistical product data were generated. Among them, the wave statistics products than in the past similar products increased the probability of effective wave height at 2.5 meters, 4.0 meters tall on the probability and effective wave effectively 6.0 meters tall on the probability, waves to distribution, swell to distribution, effective 2.5 meters tall on the days, effective wave 4.0 meters tall on the days, 6.0 meters tall on the number of the effective wave and other more practical statistical factors.
