Database of Winds and Waves

1. Winds and Waves in the North Pacific Ocean
Ship Research Institute published three long-term statistics of winds and waves on the North Pacific Ocean in these three decades. The former two, Yamanouchi et al. [1] and Takaishi et al. [2], mainly relied on the weather reports from voluntary ships in service because those were the only data source which covers the wide area of the ocean.
Recently there are other sources of winds and waves, buoy measurement, hindcasting and remote sensing from satellites. However, there are advantages and disadvantages among them. For example, the probability of high wave height of ship report tends to be smaller than the others because ships try to avoid stormy seas. The data from buoys is considered to be the most accurate one, however the number of measuring points is very limited. In order to have the reliable information, comparison of these data sources is inevitable.
With this reason, we made a new database of winds and waves in 1992 [3], which consists of weather reports, buoy and hindcast data. In this Homepage these three kinds of database are available.
