AI Technical Summary

Problems solved by technology

[0006] However, the buoy observation method is limited by the cost and application range of the buoy, and cannot effectively obtain a large amount of data, which makes the ocean wave observation effect extremely limited
[0007] In addition, although the satellite observation method can realize large-area ocean wave observation, its low resolution will lead to low precision of the ocean wave model
[0008] As for the manual observation method, the labor cost and physical cost it consumes are very high, and the data acquisition depends on the experience of the observer, which makes its traceability weak, and it is impossible to achieve long-term stable observation

Description

technical field [0001] The present application relates to the field of ocean wave observation, in particular to a method and system for training an ocean wave level observation model. Background technique [0002] At present, most of the ocean wave observations are concentrated in the coastal and offshore areas, and the constantly updated offshore ocean wave observation methods have been able to better observe the level of offshore ocean waves. However, according to the statistics of sea wave levels along the coast, light waves and below account for about 70%, and medium waves account for about 30%. Except for occasional short-term large waves affected by severe weather processes such as typhoons, there are no high-level waves. [0003] However, waves in the ocean vary depending on the season and sea area, and generally all waves in the wave scale appear. It can be seen that there is a great difference between offshore waves and ocean waves, which makes the offshore wave ob...
